(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
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.*.
