ini_get_all
Description
The ini_get_all of Options / Information for PHP gets all configuration options.
Syntax
ini_get_all(
?string $extension = null,
bool $details = true
): array|falseParameters
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).
Return
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.
NOTE: It's possible for a directive to have multiple access levels, which is why access shows the appropriate bitmask values.
