I guess the third entry is the required access level (to change this variable at runtime):
Constant Value Meaning
PHP_INI_USER 1 Entry can be set in user scripts
PHP_INI_PERDIR 2 Entry can be set in php.ini, .htaccess or httpd.conf
PHP_INI_SYSTEM 4 Entry can be set in php.ini or httpd.conf
PHP_INI_ALL 7 Entry can be set anywhere
See also the docs for ini_set()
Hugo.
ini_get_all
(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
ini_get_all — Gets all configuration options
Beschreibung
Returns all the registered configuration options.
Parameter-Liste
-
extension -
An optional extension name. If not
nullor the Stringcore, 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).
Rückgabewerte
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.
Hinweis:
It's possible for a directive to have multiple access levels, which is why
accessshows the appropriate bitmask values.
Beispiele
Beispiel #1 ini_get_all() examples
<?php
print_r(ini_get_all("pcre"));
print_r(ini_get_all());
?>Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
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
)
...
)
Beispiel #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
?>Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
Array
(
[pcre.backtrack_limit] => 100000
[pcre.recursion_limit] => 100000
)
Array
(
[allow_call_time_pass_reference] => 0
[allow_url_fopen] => 1
...
)

ini_get_all() ignores "array" ini options such as pdo.dsn.*.

If you want to load and parse your own ini file, have a look at parse_ini_file() function. Example:
<?php
// ...
$my_data = parse_ini_file($my_file, true);

You can use the following snippet on servers to grab the live/staging configs in order to be able to replicate those in your development environment. (I use `php -a` for this)
<?php
foreach (ini_get_all(null, false) as $key => $value) echo "$key=$value;\n";
?>

Since a certain PHP version (I think it's 5.2.5) it is no longer possible to override INI entrys set with php_admin_* in httpd.conf. The access level will be set to 4 (PHP_INI_SYSTEM), which is also returned by this function.
The constants mentioned below are available in PHP, but without the prefix (e.g. INI_USER, INI_PERDIR).
