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
		  ...

scandir - List files and directories inside the specified path

SYNOPSIS

       array scandir (string  $directory, [int	$sorting_order = SCANDIR_SORT_ASCENDING], [resource  $context])

DESCRIPTION

	Returns an array of files and directories from the $directory.

PARAMETERS

	      o $directory
		- The directory that will be scanned.

	      o $sorting_order
		-  By default, the sorted order is alphabetical in ascending order. If the optional $sorting_order is set to SCANDIR_SORT_DESCEND-
		ING, then the sort order is alphabetical in descending order. If it is set to SCANDIR_SORT_NONE then the result is unsorted.

	      o $context
		- For a description of the $context parameter, refer to the streams section of the manual.

RETURN VALUES

	Returns an array of filenames on success, or FALSE on failure. If $directory is not a directory, then boolean FALSE is	returned,  and	an
       error of level E_WARNING is generated.

EXAMPLES

       Example #1

	      A simple scandir(3) example

	      <?php
	      $dir    = '/tmp';
	      $files1 = scandir($dir);
	      $files2 = scandir($dir, 1);

	      print_r($files1);
	      print_r($files2);
	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [0] => .
		  [1] => ..
		  [2] => bar.php
		  [3] => foo.txt
		  [4] => somedir
	      )
	      Array
	      (
		  [0] => somedir
		  [1] => foo.txt
		  [2] => bar.php
		  [3] => ..
		  [4] => .
	      )

       Example #2

	      PHP 4 alternatives to scandir(3)

	      <?php
	      $dir = "/tmp";
	      $dh  = opendir($dir);
	      while (false !== ($filename = readdir($dh))) {
		  $files[] = $filename;
	      }

	      sort($files);

	      print_r($files);

	      rsort($files);

	      print_r($files);

	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [0] => .
		  [1] => ..
		  [2] => bar.php
		  [3] => foo.txt
		  [4] => somedir
	      )
	      Array
	      (
		  [0] => somedir
		  [1] => foo.txt
		  [2] => bar.php
		  [3] => ..
		  [4] => .
	      )

NOTES

       Tip

	      A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen(3) for more details on how	to
	      specify  the filename. See the "Supported Protocols and Wrappers" for links to information about what abilities the various wrappers
	      have, notes on their usage, and information on any predefined variables they may provide.
