Use this to replace `|` with `-` and replace `,` width `.`:

    {{age|replace({&#39;|&#39;: &quot;-&quot;, &quot;,&quot; : &quot;.&quot;})}}

Example input `31|60,` comes out as `31-60.`

To replace a string which is stored in twig variables: 

    {% set twig_content_variable= &#39;Testing to replace content&#39;%}
    {% set replace_value_var= &#39;Testing&#39; %}
    {% set replace_with_value_var = &#39;Testing complete&#39; %} 

    {{ twig_content_variable|replace({ (replace_value_var): replace_with_value_var }) }}

Also, this could be useful for getting rid of (utf-8) language chars...

    {{some_string|replace({&#39;ć&#39;:&#39;c&#39;,&#39;č&#39;:&#39;c&#39;,&#39;š&#39;:&#39;s&#39;,&#39;ž&#39;:&#39;z&#39;,&#39;đ&#39;:&#39;d&#39;,&#39;Ć&#39;:&#39;C&#39;,&#39;Č&#39;:&#39;C&#39;,&#39;Š&#39;:&#39;S&#39;,&#39;Ž&#39;:&#39;Z&#39;,&#39;Đ&#39;:&#39;D&#39;})}}



When we add a single quote inside a single quote then we face the error.

solution for that:-

    {{description|replace({&quot;\&#39;&quot;: &quot;&amp;#039&quot;})|raw }}


I want to globally replace the string foo with the string bar, using sed. This should only be done for lines which do NOT start with the string ##Input.

I can&#39;t get it to work. I tried things like this but reached a point where I&#39;m not sure if I know what I&#39;m doing:

    sed -i &#39;/^##Input/ s/foo/bar/g&#39; myfile

According to doc, calendar set() is:

http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Calendar.html#set%28int,%20int,%20int%29

    set(int year, int month, int date) 
    Sets the values for the calendar fields YEAR, MONTH, and DAY_OF_MONTH.

**code:**      

    Calendar c1 = GregorianCalendar.getInstance();
    c1.set(2000, 1, 30);  //January 30th 2000
    Date sDate = c1.getTime();

    System.out.println(sDate);

**output:**

    Wed Mar 01 19:32:21 JST 2000

The following code doesn&#39;t print out anything:

    $bool_val = (bool)false;
    echo $bool_val;

But the following code prints `1`:

    $bool_val = (bool)true;
    echo $bool_val;

Is there a better way to print `0` or `false` when `$bool_val` is `false` than adding an `if` statement?

If I have the following values:

     $var1 = AR3,373.31
    
     $var2 = 12.322,11T

How can I create a new variable and set it to a copy of the data that has any non-numeric characters removed, with the exception of commas and periods? The values above would return the following results:

     $var1_copy = 3,373.31
    
     $var2_copy = 12.322,11



Remove non-numeric characters (excluding periods and commas) from a string (i.e. remove all characters except numbers, commas, and periods)

I have a problem, I have a string array, and I want to explode in different delimiter. For Example

    $example = &#39;Appel @ Ratte&#39;;
    $example2 = &#39;apple vs ratte&#39;

and I need an array which is explode in @ or vs.

I already wrote a solution, but If everybody have a better solution please post here.

* When should `implement` or `extend` be used?
* What are some real-world examples?

Is this correct?
----------
**Implementing** appears to be a way to enforce that certain methods exists in a class, and that these methods function calls are properly formatted. Implementing is **not** a way of passing variables or &quot;settings&quot; to the class though?

*Expected real-life scenario:* I have an e-commerce platform featuring multiple payment classes that all follow the same design. When a new payment class should be added, it&#39;s really easy to follow the defined design of the `interface` to ensure that all bits and pieces are there, from the beginning.


**Extending** classes makes the extended (child?) class inherit everything from its parent class except methods &amp; variables declared as `private`?


*Expected real-life scenario:* I have one class called `sessions` with two child classes named `sessioncookies` and `databasesessions`. `sessioncookies` and `databasesessions`, together  inherit a number of mutual config options from their parent sessions, making it easy to change a config option to affect all sorts of  eventual visitor data storage.

      foreach ($a as &amp;$v) { }
      foreach ($a as $v) { }
    
      print_r($a);
    ?&gt;

I think it&#39;s a normal program but this is the output I am getting:

    )

Can someone please explain this to me?

Strange behavior Of foreach

I want to use an `AutoCompleteTextView` in my activity and populate the data as the user types by querying a web API.  How do I go about doing this?  

Do I create a new class and override `AutoCompleteTextView.performFiltering`, or do I use a custom list adapter and provide a custom `android.widget.Filter` that overrides performFiltering?  

Or is there a better way to obtain my end goal?  

I&#39;ve done something somewhat similar, but it was for the Quick Search box and it involved implementing a service, but I believe that&#39;s not what I want to do here.

I have a question regarding WordPress, specifically version 3.0 and newer. 

Does anyone know how to get an array or list of all the functions that will be applied or are &#39;registered&#39; to the_content filter? 

The idea is to generate a checkbox list of possible functions to remove from the filter, such as wpautop. I know how to remove functions from the filter with hard coded labels, but I am hoping to create a more dynamic solution.

If anyone has any ideas if this is possible and how it could be done I would be very interested. Thanks.

        });

I remember doing this before, but can&#39;t find the code. I use str_replace to replace one character like this: `str_replace(&#39;:&#39;, &#39; &#39;, $string);` but I want to replace all the following characters `\/:*?&quot;&lt;&gt;|`, without doing a str_replace for each.


Str_replace for multiple items

I&#39;m having a hard time understanding when `strtr` would be preferable to `str_replace` or vice versa. It seems that it&#39;s possible to achieve the exact same results using either function, although the order in which substrings are replaced is reversed. For example:

    echo strtr(&#39;test string&#39;, &#39;st&#39;, &#39;XY&#39;).&quot;\n&quot;;
    echo strtr(&#39;test string&#39;, array( &#39;s&#39; =&gt; &#39;X&#39;, &#39;t&#39; =&gt; &#39;Y&#39;, &#39;st&#39; =&gt; &#39;Z&#39; )).&quot;\n&quot;;
    echo str_replace(array(&#39;s&#39;, &#39;t&#39;, &#39;st&#39;), array(&#39;X&#39;, &#39;Y&#39;, &#39;Z&#39;), &#39;test string&#39;).&quot;\n&quot;;
    echo str_replace(array(&#39;st&#39;, &#39;t&#39;, &#39;s&#39;), array(&#39;Z&#39;, &#39;Y&#39;, &#39;X&#39;), &#39;test string&#39;);

This outputs

    YeXY XYring
    YeZ Zring
    YeXY XYring
    YeZ Zring

Aside from syntax, is there any benefit to using one over the other? Any cases where one would not be sufficient to achieve a desired result?

I have a Symfony2 Twig template. I want to output the value of a config parameter in this twig template (a version number). Therefore I defined the config parameter like this:

    parameters:
        app.version: 0.1.0

I&#39;m able to use this config parameter in Controllers but I have no clue how to get it in my Twig template.

I have a multidimensional array where some objects exist and others don&#39;t. I keep getting a

**Method &quot;code&quot; for object &quot;stdClass&quot; does not exist in...**?

The code I am using in my template is:

    {% for item in items %}
        &lt;p&gt;{% if item.product.code %}{{ item.product.code }}{% endif %}&lt;/p&gt;
    {% endfor %}

Some products do not have this code and unfortunately this data structure is provided via a feed, so I cannot change it.

When I looked at the Twig documentation I interpreted that if an object or method was not there it would just return null?

How do you check if an object exists in the Twig templating engine in Symfony2?

View layer pattern where you only present what you have been given is fine and all, but how do you know what is available? Is there a &quot;list all defined variables&quot; functionality in TWIG? *Is there a way to dump a variable?*

The solution I found by searching for it was to define a function where I can use my [existing php debug tools][1] by [injecting a function][2], but all references I have found to that includes these nice two lines of code, but nowhere is it specified where to place them. Going by the fact that they need a **$loader** variable defined, I tried /app/config/autoload.php but the $loader there was the wrong kind. *Where do I place the php code for adding a twig function?*

How to var_dump variables in twig templates?

I am using [Twig][1] as templating engine and I am really loving it. However, now I have run in a situation which definitely mustbe accomplishable in a simpler way than I have found.

What I have right now is this:

    {% for myVar in someArray %}    
        {% set found = 0 %}
	    {% for id, data in someOtherArray %}
		    {% if id == myVar %}
			    {{ myVar }} exists within someOtherArray.
			    {% set found = 1 %} 
		    {% endif %}
	    {% endfor %}

	    {% if found == 0 %}
			{{ myVar }} doesn&#39;t exist within someOtherArray.
	    {% endif %}
    {% endfor %}


What I am looking for is something more like this:

    {% for myVar in someArray %}    
	    {% if myVar is in_array(array_keys(someOtherArray)) %}
           {{ myVar }} exists within someOtherArray.
        {% else %}
           {{ myVar }} doesn&#39;t exist within someOtherArray.
        {% endif %}
    {% endfor %}

Is there a way to accomplish this which I haven&#39;t seen yet?

If I need to create my own extension, how can I access myVar within the test function?

Thanks for your help!
