ini_get_all - Gets all configuration options

SYNOPSIS

       array ini_get_all ([string  $extension], [bool  $details = true])

DESCRIPTION

	Returns all the registered configuration options.

PARAMETERS

	      o $extension
		- An optional extension name. If set, the function return only options specific for that extension.

	      o $details
		- Retrieve details settings or only the current value for each setting. Default is TRUE (retrieve details).

RETURN VALUES

	Returns an associative array with directive name as the array key.

	When  $details	is TRUE (default) the array will contain global_value (set in php.ini), local_value (perhaps set with ini_set(3) or .htac-
       cess), and access (the access level).

	When $details is FALSE the value will be the current value of the option.

	See the manual section for information on what access levels mean.

       Note

	       It's possible for a directive to have multiple access levels, which is why access shows the appropriate bitmask values.

EXAMPLES

	      <?php

	      print_r(ini_get_all());
	      ?>

	      The above example will output something similar to:

	      (
		  [pcre.backtrack_limit] => Array
		      (
			  [global_value] => 100000

			  [local_value] => 100000
			  [access] => 7

		      (

       Example #2

	      Disabling $details

	      <?php
	      print_r(ini_get_all("pcre", false)); // Added in PHP 5.3.0
	      print_r(ini_get_all(null, false)); // Added in PHP 5.3.0
	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [pcre.backtrack_limit] => 100000
		  [pcre.recursion_limit] => 100000
	      )

natsort - Sort an array using a ";natural order" algorithm

SYNOPSIS

       bool natsort (array  &$array)

DESCRIPTION

	This  function	implements  a  sort  algorithm that orders alphanumeric strings in the way a human being would while maintaining key/value
       associations. This is described as a "natural ordering". An example of the difference between  this  algorithm  and  the  regular  computer
       string sorting algorithms (used in sort(3)) can be seen in the example below.

PARAMETERS

	      o $array
		- The input array.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

	      asort($array1);

	      The above example will output:

	      Array
	      (
		  [3] => img1.png
