    ini_get_all

    (PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)

    ini_get_all — Gets all configuration options

    Descrição

    ini_get_all(?string $extension = null, bool $details = true): array|false

    Returns all the registered configuration options.

    Parâmetros

    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).

    Valor Retornado

    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.

    Nota:

    It's possible for a directive to have multiple access levels, which is why access shows the appropriate bitmask values.

    Exemplos

    Exemplo #1 ini_get_all() examples

    <?php
    print_r    (ini_get_all("pcre"));
    print_r(ini_get_all());
    ?>

    O exemplo acima produzirá algo semelhante a:

    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
        )

    ...

)

    Exemplo #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
    ?>

    O exemplo acima produzirá algo semelhante a:

    Array
(
    [pcre.backtrack_limit] => 100000
    [pcre.recursion_limit] => 100000
)
Array
(
    [allow_call_time_pass_reference] => 0
    [allow_url_fopen] => 1
    ...
)

    Nota:

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

    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()

    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).
