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

       Example #1

	      ini_get_all(3) examples

	      <?php
	      print_r(ini_get_all("pcre"));
	      print_r(ini_get_all());
	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [pcre.backtrack_limit] => Array
		      (
			  [global_value] => 100000
			  [local_value] => 100000
			  [access] => 7
		      )

		  [pcre.recursion_limit] => Array
		      (
			  [global_value] => 100000
			  [local_value] => 100000
			  [access] => 7
		      )

	      )
	      Array
	      (
		  [allow_call_time_pass_reference] => Array
		      (
			  [global_value] => 0
			  [local_value] => 0
			  [access] => 6
		      )

		  [allow_url_fopen] => Array
		      (
			  [global_value] => 1
			  [local_value] => 1
			  [access] => 4
		      )

		  ...

	      )

       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
	      )
	      Array
	      (
		  [allow_call_time_pass_reference] => 0
		  [allow_url_fopen] => 1
		  ...
	      )
