(PHP 4 >= 4.2.0, PHP 5)
ini_get_all — Gets all configuration options
$extension
[, bool $details = true
]] )Returns all the registered configuration options.
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).
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.

Example #1 ini_get_all() examples
<?php
print_r(ini_get_all("pcre"));
print_r(ini_get_all());
?>
以上例程的输出类似于：
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

Array
(
[pcre.backtrack_limit] => 100000
[pcre.recursion_limit] => 100000
)
