PHP Manual: php_ini_scanned

php_ini_scanned_files

(PHP 4 >= 4.3.0, PHP 5)

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

Description

string php_ini_scanned_files ( void )

php_ini_scanned_files() returns a comma-separated list of configuration files parsed after php.ini. These files are found in a directory defined by the --with-config-file-scan-dir option which is set during compilation.

Returns a comma-separated string of .ini files on success. If the directive --with-config-files-scan-dir wasn'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().

The returned configuration files also include the path as declared in the --with-config-file-scan-dir option. Also, each comma is followed by a newline.

Example 1. 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";
        }
    }
}
?>
