WeberDev.com -> PHP Manual -> Gets all configuration options

Description

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

Returns all the registered configuration options.

Parameters

extension: An optional extension name. If set, the function return only options specific for that extension.
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() or .htaccess), 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() 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
?>
