Description
array 
ini_get_all ( [string extension] )
     Returns all the registered configuration options as an
     associative array.  If the optional extension
     parameter is set, returns only options specific for that
     extension.
    
     The returned array uses the directive name as the array key, with
     elements of that array being global_value (set in
     php.ini), local_value (perhaps set with
     ini_set() or .htaccess), and
     access (the access level).  See the manual section
     on configuration changes
     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.
     
     
Example 1. A ini_get_all() example 
<?php $inis = ini_get_all();
  print_r($inis);
  ?>

       Partial output may look like:
       Array
(
    [allow_call_time_pass_reference] => Array
    (
        [global_value] => 1
        [local_value] => 1
        [access] => 6
    )
    [allow_url_fopen] => Array
    (
        [global_value] => 1
        [local_value] => 1
        [access] => 7
    )
    ...
