I am generating an XML document in Python using an [`ElementTree`][1], but the `tostring` function doesn&#39;t include an [XML declaration][2] when converting to plaintext.

&lt;!-- language: lang-python --&gt;

    from xml.etree.ElementTree import Element, tostring

    document = Element(&#39;outer&#39;)
    node = SubElement(document, &#39;inner&#39;)
    node.NewValue = 1
    print tostring(document)  # Outputs &quot;&lt;outer&gt;&lt;inner /&gt;&lt;/outer&gt;&quot;

I need my string to include the following XML declaration:

&lt;!-- language: lang-xml--&gt;

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot; standalone=&quot;yes&quot; ?&gt;

However, there does not seem to be any documented way of doing this.

Is there a proper method for rendering the XML declaration in an `ElementTree`?

I have a set of Controllers in the application and a class annotated as `@ControllerAdvice` which sets up certain data elements that are used in each of these controllers. I&#39;m using `Spring MVC 3.2` and have Junits for these controllers. When I run the Junit the control is not going to the `ControllerAdvice` class wheres it works fine if I deploy the app in `Tomcat` and submit a request through browser. 

Any thoughts please?.

I want to be able to let a PHP program wait for user&#39;s input. For example:

1. Script requests authorization code from server (this code will be sent via e-mail)
2. Script waits for user to enter authorization code
3. Script continues

How should I do step 2? (Is it possible?)

Is there a way to make sure a received file is an image in `PHP`?

Testing for the extension doesn&#39;t sound very secure to me as you could upload a `script` and change its extension to whatever you want.

I&#39;ve tried to use `getimagesize` too, but there might be something more suited for that particular problem.

PHP check if file is an image

I am using a loop to get values from my database and my result is like:

    &#39;name&#39;, &#39;name2&#39;, &#39;name3&#39;,

And I want it like this:

    &#39;name&#39;, &#39;name2&#39;, &#39;name3&#39;

I want to remove the comma after the last value of the loop.

I&#39;m struggling to write readable and easy to understand documentation that describes the multi-tree structure for Array options that are passed to a function.

Here is an example array structure.

    $arr = [
       &#39;fields&#39; =&gt; [
           &#39;title&#39; =&gt; [
               &#39;name&#39;     =&gt; &#39;Document.title&#39;,
               &#39;format&#39;   =&gt; &#39;string&#39;,
               &#39;readonly&#39; =&gt; true
           ]
       ]
    ];

There are many possible options for the above array, but this is used as a parameter to a function that understands that structure.

    function doSomething(array $arr) { ... }

I&#39;d like to document how the array should be structured in PHPDoc, but I&#39;m not sure what the correct approach is.

Here is what I have now.

	/**
	 * Holds configuration settings for each field in a model.
	 * Defining the field options
	 *
	 * array[&#39;fields&#39;] array Defines the feilds to be shown by scaffolding.
	 * array[&#39;fields&#39;][fieldName] array Defines the options for a field, or just enables the field if array is not applied.
	 * array[&#39;fields&#39;][fieldName][&#39;name&#39;] string Overrides the field name (default is the array key)
	 * array[&#39;fields&#39;][fieldName][&#39;model&#39;] string (optional) Overrides the model if the field is a belongsTo assoicated value.
	 * array[&#39;fields&#39;][fieldName][&#39;width&#39;] string Defines the width of the field for paginate views. Examples are &quot;100px&quot; or &quot;auto&quot;
	 * array[&#39;fields&#39;][fieldName][&#39;align&#39;] string Alignment types for paginate views (left, right, center)
	 * array[&#39;fields&#39;][fieldName][&#39;format&#39;] string Formatting options for paginate fields. Options include (&#39;currency&#39;,&#39;nice&#39;,&#39;niceShort&#39;,&#39;timeAgoInWords&#39; or a valid Date() format)
	 * array[&#39;fields&#39;][fieldName][&#39;title&#39;] string Changes the field name shown in views.
	 * array[&#39;fields&#39;][fieldName][&#39;desc&#39;] string The description shown in edit/create views.
	 * array[&#39;fields&#39;][fieldName][&#39;readonly&#39;] boolean True prevents users from changing the value in edit/create forms.
	 * array[&#39;fields&#39;][fieldName][&#39;type&#39;] string Defines the input type used by the Form helper (example &#39;password&#39;)
	 * array[&#39;fields&#39;][fieldName][&#39;options&#39;] array Defines a list of string options for drop down lists.
	 * array[&#39;fields&#39;][fieldName][&#39;editor&#39;] boolean If set to True will show a WYSIWYG editor for this field.
	 * array[&#39;fields&#39;][fieldName][&#39;default&#39;] string The default value for create forms.
	 *
	 * @param array $arr (See above)
	 * @return Object A new editor object.
	 **/

My problem is that when the HTML document is generated, it&#39;s not formatted very nicely. Additionally, I&#39;m not sure the above is clearly explains the array structure.

Is there an alternative approach?

    // Difference from a date in the future:
    $a = new DateTime(&#39;2000-01-01&#39;);
    $b = new DateTime(&#39;2000-01-05&#39;);
    $interval = $b-&gt;diff($a);
    return $interval-&gt;days;             // Returns 4


    // Difference from a date in the past:
    $a = new DateTime(&#39;2000-01-01&#39;);
    $b = new DateTime(&#39;1999-12-28&#39;);
    $interval = $a-&gt;diff($b);           // Arguments swapped
    return $interval-&gt;days;             // Returns 4

Why do both of these functions return positive 4?
How do I return a negative number if a date is in the past?

I have setup an nginx server with php5-fpm.  When I try to load the site I get a blank page with no errors.  Html pages are served fine but not php.  I tried turning on display_errors  in php.ini but no luck.  php5-fpm.log is not producing any errors and neither is nginx.

**nginx.conf**

When I download GCC, it also has a `.sig` file, and I think it is provided to verify downloaded file.
(I downloaded GCC from [here](http://ftp.kaist.ac.kr/gnu/gnu/gcc/gcc-4.7.2/)).
    

But I can&#39;t figure out how should I use it. I tried `gpg`, but it complains about public key.

    [root@localhost src]# gpg --verify gcc-4.7.2.tar.gz.sig gcc-4.7.2.tar.gz
    gpg: Signature made Thu 20 Sep 2012 07:30:44 PM KST using DSA key ID C3C45C06
    gpg: Can&#39;t check signature: No public key

I&#39;m new to php and wanted to run php from command line. I have installed WAMP and set the &quot;System Variables&quot; to my php folder ( which is `C:\wamp\bin\php\php5.4.3`).

When i go to `Run` -&gt; `CMD` -&gt; Type `php -a` and hit enter, it says `interactive mode enabled`. But when I write `echo &#39;Hi&#39;;` it shows nothing.

I even don&#39;t see anything like &#39;php &gt;&quot; when i type `php -a` and hit enter.

The [Rust tutorial][1] does not explain how to take parameters from the command line. `fn main()` is only shown with an empty parameter list in all examples.

What is the correct way of accessing command line parameters from `main`?

I want to get headerless CSV data from the output of a query to MySQL on the command line. I&#39;m running this query on a different machine from the MySQL server, so all those Google answers with &quot;INTO OUTFILE&quot; are no good. 

So I run `mysql -e &quot;select people, places from things&quot;`. That outputs stuff that looks kinda like this:

    +--------+-------------+
    | people | places      |
    +--------+-------------+
    |   Bill | Raleigh, NC |
    +--------+-------------+

Well, that&#39;s no good. But hey, look! If I just pipe it to _anything_, it turns it into a tab-separated list: 

    people  places
    Bill    Raleigh, NC

That&#39;s better- at least it&#39;s programmatically parseable. But I don&#39;t want TSV, I want CSV, and I don&#39;t want that header. I can get rid of the header with `mysql &lt;stuff&gt; | tail -n +2`, but that&#39;s a bother I&#39;d like to avoid if MySQL just has a flag to omit it. And I can&#39;t just replace all tabs with commas, because that doesn&#39;t handle content with commas in it.

So, how can I get MySQL to omit the header and give me data in CSV format?

I have a backup script for my MySQL database, using `mysqldump` with the `--tab` option so it produces a `.sql` file for the structure and a `.txt` file (pipe-separated) for the content.

Some tables have foreign keys, so when I import it I&#39;m getting the error:

&gt; ERROR 1217 (23000) at line 8: Cannot delete or update a parent row: a foreign key constraint fails

I know about using `SET FOREIGN_KEY_CHECKS=0` (and `SET FOREIGN_KEY_CHECKS=1` afterward). If I add those to each `.sql` file then the import works. But then obviously on the next `mysqldump` those get overwritten.

I also tried running it as a separate command, like below but the error comes back:

    echo &quot;SET FOREIGN_KEY_CHECKS=0&quot; | mysql [user/pass/database] 
    [all the imports]
    echo &quot;SET FOREIGN_KEY_CHECKS=1&quot; | mysql [user/pass/database] 

Is there some other way to disable FK checks on the command line?
