(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
ini_get_all — Gets all configuration options
$extension
= null
, bool $details
= true
): array|falseReturns all the registered configuration options.
extension
An optional extension name. If not null
or the string core
, the function returns only options
specific for that extension.
details
Retrieve details settings or only the current value for each setting.
Default is true
(retrieve details).
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.*.
