(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)

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


php_ini_scanned_files(): string|false

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.


This function has no parameters.

Return Values

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().


Example #1 A simple example to list the returned ini files

if ($filelist php_ini_scanned_files()) {
    if (
strlen($filelist) > 0) {
$files explode(','$filelist);

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