My functions.php includes other function files located within a 'functions' directory.

Currently they're individually added, in the format of this example:


How can I modify this to include all files within the 'functions' directory, without listing them individually?

You can include/require all *.php files recursively using following function.

foreach(glob(get_template_directory() . "/*.php") as $file){
    require $file;

Alternatively You can use following function as-well.

$Directory = new RecursiveDirectoryIterator(get_template_directory().'functions/');
$Iterator = new RecursiveIteratorIterator($Directory);
$Regex = new RegexIterator($Iterator, '/^.+\.php$/i', RecursiveRegexIterator::GET_MATCH);

foreach($Regex as $yourfiles) {
    include $yourfiles->getPathname();

P.S Got the solution From Here.

  • @ JItendra Rana ... Thanks. I'm getting various errors with the updated code, so will instead use your previous suggestion, which I think was: foreach(glob('/add_path_to_theme/wp-content/themes/theme-name/functions/*.php') as $file) {include $file;} If that is your code, it might be worth re-adding it to your update so others can access it.

Here's how I did it from my functions.php file in WordPress:

 * Functions
 * Require all PHP files in the /functions/ directory
foreach (glob(get_template_directory() . "/functions/*.php") as $function) {
    $function= basename($function);
    require get_template_directory() . '/functions/' . $function;
