run code in 300+ PHP versions simultaneously
<?php $show = array( 'mon' => false, 'tue' => false, 'wed' => false, 'thu' => false, 'fri' => false, 'sat' => false, 'sun' => false ); $keys = array_keys($show); foreach (range(0,6) as $index) { $key = $keys[$index]; $show[$key] |= true; // in your case |= isset($post[$key]); } var_dump($show);
Output for git.master, git.master_jit, rfc.property-hooks
