To remove a globally installed package run:

&lt;!-- language: bash --&gt;

    composer global remove phpunit/phpunit

`global` command lets you to run many commands like `install`, `require` or `update` as if you were running them from the `COMPOSER_HOME` directory. 

Read the related documentation here: http://getcomposer.org/doc/03-cli.md#global

`COMPOSER_HOME` depends on your system (on Linux it&#39;s `~/.composer`), see http://getcomposer.org/doc/03-cli.md#composer-home for more details.

Also you can use another way

    cd $HOME/.config/composer

And in `composer.json` file remove some require positions

After all execute `composer update`
This is a long way, but more clear

I have a simple php structure with 3 nested arrays. 

I do not use particular objects and I build myself the arrays with 2 nested loops. 

Here is a sample of the var_dump of the array I want to convert to Json. 

    array (size=2)
      &#39;tram B&#39; =&gt; 
        array (size=2)
          0 =&gt; 
            array (size=3)
              &#39;name&#39; =&gt; string &#39;Ile Verte&#39; (length=9)
              &#39;distance&#39; =&gt; int 298
              &#39;stationID&#39; =&gt; int 762
          1 =&gt; 
            array (size=3)
              &#39;name&#39; =&gt; string &#39;La Tronche H&#244;pital&#39; (length=18)
              &#39;distance&#39; =&gt; int 425
              &#39;stationID&#39; =&gt; int 771
      16 =&gt; 
        array (size=4)
          0 =&gt; 
            array (size=3)
              &#39;name&#39; =&gt; string &#39;Bastille&#39; (length=8)
              &#39;distance&#39; =&gt; int 531
              &#39;stationID&#39; =&gt; int 397
          1 =&gt; 
            array (size=3)
              &#39;name&#39; =&gt; string &#39;Xavier Jouvin&#39; (length=13)
              &#39;distance&#39; =&gt; int 589
              &#39;stationID&#39; =&gt; int 438

In another script I have a similar structure and `json_encode` works fine. 
So I don&#39;t understand why `json_encode` won&#39;t work here.

Edit : there seems to be a problem with the encoding. When `mb_detect_encoding` returns ASCII, the `json_encode` works but when it returns UTF8, it doesn&#39;t work anymore.  

Edit2 : `json_last_error()` returns `JSON_ERROR_UTF8` which means : [Malformed UTF-8 characters, possibly incorrectly encoded][1].

Why would json_encode return an empty string

I was trying to count words in a text in this way:


    function WordCount(str) {
      var totalSoFar = 0;
      for (var i = 0; i &lt; WordCount.length; i++)
        if (str(i) === &quot; &quot;) { // if a space is found in str
          totalSoFar = +1; // add 1 to total so far
      }
      totalsoFar += 1; // add 1 to totalsoFar to account for extra space since 1 space = 2 words
    }

    console.log(WordCount(&quot;Random String&quot;));

I think I have got this down pretty well, except I think that the `if` statement is wrong. The part that checks if `str(i)` contains a space and adds 1.

**Edit:**

I found out (thanks to Blender) that I can do this with a lot less code:
   
    function WordCount(str) { 
      return str.split(&quot; &quot;).length;
    }

    console.log(WordCount(&quot;hello world&quot;));

What would be the most elegant way to get a random boolean true/false in PHP?

I can think of:

    $value = (bool)rand(0,1);

But does casting an integer to boolean bring any disadvantages?

Or is this an &quot;official&quot; way to do this?



Get random boolean true/false in PHP

I&#39;ve been struggling with this question for quite some months now, but I haven&#39;t been in a situation that I needed to explore all possible options before. Right now, I feel like it&#39;s time to get to know the possibilities and create my own personal preference to use in my upcoming projects.

**Let me first sketch the situation I&#39;m looking for**

I&#39;m about to upgrade/redevelop a content management system which I&#39;ve been using for quite a while now. However, I&#39;m feeling multi language is a great improvement to this system. Before I did not use any frameworks but I&#39;m going to use Laraval4 for the upcoming project. Laravel seems the best choice of a cleaner way to code PHP. `Sidenote: Laraval4 should be no factor in your answer`. I&#39;m looking for general ways of translation that are platform/framework independent.

**What should be translated**

As the system I am looking for needs to be as user friendly as possible the method of managing the translation should be inside the CMS. There should be no need to start up an FTP connection to modify translation files or any html/php parsed templates.

Furthermore, I&#39;m looking for the easiest way to translate multiple database tables perhaps without the need of making additional tables.

**What did I come up with myself**

As I&#39;ve been searching, reading and trying things myself already. There are a couple of options I have. But I still don&#39;t feel like I&#39;ve reached a best practice method for what I am really seeking. Right now, this is what I&#39;ve come up with, but this method also has it side effects.

 1. **PHP Parsed Templates**: the template system should be parsed by PHP. This way I&#39;m able to insert the translated parameters into the HTML without having to open the templates and modify them. Besides that, PHP parsed templates gives me the ability to have 1 template for the complete website instead of having a subfolder for each language (which I&#39;ve had before). The method to reach this target can be either Smarty, TemplatePower, Laravel&#39;s Blade or any other template parser. As I said this should be independent to the written solution.
 2. **Database Driven**: perhaps I don&#39;t need to mention this again. But the solution should be database driven. The CMS is aimed to be object oriented and MVC, so I would need to think of a logical data structure for the strings. As my templates would be structured: templates/Controller/View.php perhaps this structure would make the most sense: `Controller.View.parameter`. The database table would have these fields a long with a `value` field. Inside the templates we could use some sort method like `echo __(&#39;Controller.View.welcome&#39;, array(&#39;name&#39;, &#39;Joshua&#39;))` and the parameter contains `Welcome, :name`. Thus the result being `Welcome, Joshua`. This seems a good way to do this, because the parameters such as :name are easy to understand by the editor.
 3. **Low Database Load**: Of course the above system would cause loads of database load if these strings are being loaded on the go. Therefore I would need a caching system that re-renders the language files as soon as they are edited/saved in the administration environment. Because files are generated, also a good file system layout is needed. I guess we can go with `languages/en_EN/Controller/View.php` or .ini, whatever suits you best. Perhaps an .ini is even parsed quicker in the end. This fould should contain the data in the `format parameter=value;`
. I guess this is the best way of doing this, since each View that is rendered can include it&#39;s own language file if it exists. Language parameters then should be loaded to a specific view and not in a global scope to prevent parameters from overwriting each other.
 4. **Database Table translation**: this in fact is the thing I&#39;m most worried about. I&#39;m looking for a way to create translations of News/Pages/etc. as quickly as possible. Having two tables for each module (for example `News` and `News_translations`) is an option but it feels like to much work to get a good system. One of the things I came up with is based on a `data versioning` system I wrote: there is one database table name `Translations`, this table has a unique combination of `language`, `tablename` and `primarykey`. For instance: en_En / News / 1 (Referring to the English version of the News item with ID=1). But there are 2 huge disadvantages to this method: first of all this table tends to get pretty long with a lot of data in the database and secondly it would be a hell of a job to use this setup to search the table. E.g. searching for the SEO slug of the item would be a full text search, which is pretty dumb. But on the other hand: it&#39;s a quick way to create translatable content in every table very fast, but I don&#39;t believe this pro overweights the con&#39;s.
 5. **Front-end Work**: Also the front-end would need some thinking. Of course we would store the available languages in a database and (de)active the ones we need. This way the script can generate a dropdown to select a language and the back-end can decide automatically what translations can be made using the CMS. The chosen language (e.g. en_EN) would then be used when getting the language file for a view or to get the right translation for a content item on the website.

So, there they are. My ideas so far. They don&#39;t even include localization options for dates etc yet, but as my server supports PHP5.3.2+ the best option is to use the intl extension as explained here: http://devzone.zend.com/1500/internationalization-in-php-53/ - but this would be of use in any later stadium of development. For now the main issue is how to have the best practics of translation of the content in a website.

Besides everything I explained here, I still have another thing which I haven&#39;t decided yet, it looks like a simple question, but in fact it&#39;s been giving me headaches:

**URL Translation? Should we do this or not? and in what way?**

So.. if I have this url: `http://www.domain.com/about-us` and English is my default language. Should this URL be translated into `http://www.domain.com/over-ons` when I choose Dutch as my language? Or should we go the easy road and simply change the content of the page visible at `/about`. The last thing doesn&#39;t seem a valid option because that would generate multiple versions of the same URL, this indexing the content will fail the right way.

Another option is using `http://www.domain.com/nl/about-us` instead. This generates at least a unique URL for each content. Also this would be easier to go to another language, for example `http://www.domain.com/en/about-us` and the URL provided is easier to understand for both Google and Human visitors. Using this option, what do we do with the default languages? Should the default language remove the language selected by default? So redirecting `http://www.domain.com/en/about-us` to `http://www.domain.com/about-us` ... In my eyes this is the best solution, because when the CMS is setup for only one language there is no need to have this language identification in the URL.
 
And a third option is a combination from both options: using the &quot;language-identification-less&quot;-URL (`http://www.domain.com/about-us`) for the main language. And use an URL with a translated SEO slug for sublanguages: `http://www.domain.com/nl/over-ons` &amp; `http://www.domain.com/de/uber-uns`

I hope my question gets your heads cracking, they cracked mine for sure! It did help me already to work things out as a question here. Gave me a possibility to review the methods I&#39;ve used before and the idea&#39;s I&#39;m having for my upcoming CMS.

I would like to thank you already for taking the time to read this bunch of text!

`// Edit #1`: 

I forgot to mention: the __() function is an alias to translate a given string. Within this method there obviously should be some sort of fallback method where the default text is loaded when there are not translations available yet. If the translation is missing it should either be inserted or the translation file should be regenerated.

Best practice multi language website

I have the need to concatenate a string with a field value in a MySQL query in order to LEFT JOIN two tables.

Table one has a column called &quot;category_id&quot; with numeric values, such as 61, 78, 94 and such.

Table two has a column called &quot;query&quot; which refers to a request route mechanism, and it has values such as &quot;product_id=68&quot;, &quot;category_id=74&quot;, &quot;manufacturer_id=99&quot; and so on.

So in my query I require to join the tables when ever a concatenated string derived from a set string and the value of the &quot;category_id&quot; column matches the query field.

My SQL statement is currently:

    SELECT * FROM tableOne 
    LEFT JOIN tableTwo
    ON tableTwo.query = &#39;category_id=&#39; + tableOne.category_id

I have tried using the || operator instead of the + operator, but still no luck. Is it possible to do this in MySQL, or have I jumped the gun here?

Concatenate string with field value in MySQL

I found some websites that claim to verify if email addresses are valid. Is it possible to check if an email address is valid using just PHP? 

    &lt;?php
        if($_POST[&#39;email&#39;] != &#39;&#39;){
            // The email to validate
            $email = $_POST[&#39;email&#39;];

            // An optional sender
            function domain_exists($email, $record = &#39;MX&#39;){
                list($user, $domain) = explode(&#39;@&#39;, $email);
                return checkdnsrr($domain, $record);
            }
            if(domain_exists($email)) {
                echo(&#39;This MX records exists; I will accept this email as valid.&#39;);
            }
            else {
                echo(&#39;No MX record exists;  Invalid email.&#39;);
            }
        }
    ?&gt;
    &lt;form method=&quot;POST&quot;&gt;
        &lt;input type=&quot;text&quot; name=&quot;email&quot;&gt;
        &lt;input type=&quot;submit&quot; value=&quot;submit&quot;&gt;
    &lt;/form&gt;

This is what I have right now. **It checks if the domain exist**, *but it cannot check if the
user&#39;s email exist on that domain*. Is it possible to do that using PHP?


How to check if an email address is real or valid using PHP

I&#39;m receiving a date string from an API, and it is formatted as `yyyy-mm-dd`.

I am currently using a regex to validate the string format, which works ok, but I can see some cases where it could be a correct format according to the string but actually an invalid date. i.e. `2013-13-01`, for example.

Is there a better way in PHP to take a string such as `2013-13-01` and tell if it is a valid date or not for the format `yyyy-mm-dd`?



Correctly determine if date string is a valid date in that format

Why does it take up to two minutes for my composer dependencies to update, even when there have been no changes?

A [popular suggestion][1] is to append the `--prefer-dist` flag:

    php composer.phar update --prefer-dist

But this makes no difference in my case. Below is my composer.json file – am I missing something obvious?

I&#39;m using the ZF2 skeleton app and it has a .gitignore that prevents external libraries from being commited to git. While debugging I like to go and change stuff here and there in the libraries&#39; source to learn how things work. If these were version controlled it would be very easy to revert them back to their original state.

How can I force Composer to reinstall a particular framework so that I can get a fresh -unmodified- copy again?

PS: Please don&#39;t suggest removing the .gitignore file since it&#39;s there for a reason; it prevents my third party libraries from getting into my app&#39;s repository. I can always install them during an automated deployment.

I am trying to get Composer do download the latest commit for the Behat/MinkSelenium2Driver package. That particular repo only has a master branch. I have tried every method I can think of, including deleting the files and letting it pull them back in, to get it to work but it doesn&#39;t.

How would I get it to pull in latest committed files or at least those from the commit I list below?

Specifically I want to get this commit:

I have looked for the problem in the Internet and saw that the memory is the problem, I think I don&#39;t have enough RAM available, I&#39;ve checked this I have about 411mb free.
Does composer really need more RAM?

I am trying to change the working directory of my Node.js script when it is run from a bin script. I have something like the following:

    #!/usr/bin/env node
    process.chdir(&#39;/Users&#39;)

When I then run this file with `./bin/nodefile`, it exits, but the working directory of the current shell context has not changed. I have also tried [shelljs][1], but that does not work either.

What is the best way to do this? I understand it&#39;s working but it&#39;s just in a separate process.
