(PHP 4 >= 4.2.0, PHP 5)
ini_get_all — Gets all configuration options
Returns all the registered configuration options.
An optional extension name. If set, the function return only options specific for that extension.
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.
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.
| 版本 | 说明 |
|---|---|
| 5.3.0 | Added details . |
