(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
ini_get_all — Gets all configuration options
ini_get_all(?string $extension = null, bool $details = true): array|false
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
accessshows 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.*.
