how use php mkdir function recursively skip existing directory , create new 1 string $pathname

// works fine if directories don't exist mkdir($root_dir . '/demo/test/one', 0775, true);  // throw error - message: mkdir(): file exists mkdir($root_dir . '/demo/test/two', 0775, true);

what solution?

your code should work is, problem happens when/if run second time per @chris85's suggestion can check if exists beforehand.

<?php // given $root_dir = __dir__;  // , want have these $dirs = [     $root_dir . '/demo/test/one',     $root_dir . '/demo/test/tow',     $root_dir . '/demo/test/three',     $root_dir . '/demo/test/four',     $root_dir . '/demo/test/and/so/on', ];  // check if they're not exists , create them foreach ($dirs $dir) {     if (!is_dir($dir)) {         mkdir($dir, 0775, true);     } }
