ini_alter
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).
ini_get_all
(PHP 4 >= 4.2.0, PHP 5)
ini_get_all — Gets all configuration options
说明
array ini_get_all
([ string $extension
[, bool $details = true
]] )
Returns all the registered configuration options.
参数
- extension
-
An optional extension name. If set, the function return only options specific for that extension.
- details
-
Retrieve details settings or only the current value for each setting. Default is TRUE (retrieve details).
返回值
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.

范例
Example #1 ini_get_all() examples
<?php
print_r(ini_get_all("pcre"));
print_r(ini_get_all());
?>
上例的输出类似于：
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
?>
上例的输出类似于：
Array
(
[pcre.backtrack_limit] => 100000
[pcre.recursion_limit] => 100000
)
Array
(
[allow_call_time_pass_reference] => 0
[allow_url_fopen] => 1
...
)

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
