(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
ini_get_all — Gets all configuration options
Returns all the registered configuration options.
Returns an associative array with directive name as the array key. Returns false
and raises an E_WARNING
level error if the extension
doesn't exist.
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.
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
?>
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 ... )
Note:
ini_get_all() ignores "array" ini options such as pdo.dsn.*.
