ini_get

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.

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

例子 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 ) ... )

I guess the third entry is the required access level (to change this variable at runtime):



Constant           Value      Meaning 

PHP_INI_USER      1          Entry can be set in user scripts 

PHP_INI_PERDIR    2          Entry can be set in php.ini, .htaccess or httpd.conf  

PHP_INI_SYSTEM    4          Entry can be set in php.ini or httpd.conf  

PHP_INI_ALL       7          Entry can be set anywhere
