php_ini_scanned_files

Return a list of .ini files parsed from the additional ini dir

&reftitle.description; ``string``false```php_ini_scanned_files`

`php_ini_scanned_files` returns a comma-separated list of configuration files parsed after &php.ini;. The directories searched are set by a compile time option and, optionally, by an environment variable at run time: more information can be found in the installation guide.

The returned configuration files include the full path.

&reftitle.parameters; &no.function.parameters;
&reftitle.returnvalues;

Returns a comma-separated string of .ini files on success. Each comma is followed by a newline. If the configure directive `--with-config-file-scan-dir` wasn't set and the `PHP_INI_SCAN_DIR` environment variable isn't set, &false; is returned. If it was set and the directory was empty, an empty string is returned. If a file is unrecognizable, the file will still make it into the returned string but a PHP error will also result. This PHP error will be seen both at compile time and while using `php_ini_scanned_files`.

### A simple example to list the returned ini files

    <?php
    if ($filelist = php_ini_scanned_files()) {
        if (strlen($filelist) > 0) {
            $files = explode(',', $filelist);

            foreach ($files as $file) {
                echo "<li>" . trim($file) . "</li>\n";
            }
        }
    }
    ?>
