note 126433 deleted from function.array-key-exists by crell

Note Submitter: johannes dot kingma at gmail dot com ---- I often need a value from an array and if missing, some default. So this became a staple in every utils.php file I include in my projects: <?php /** * get array value if key exist otherwise default * @param string $key needle * @param mixed[] $array haystack * @param mixed $default value if needle not found */ function array_value($key, $array, $default = '') { if (array_key_exists($key, $array)) return $array[$key]; return $default; } ?> Works great for $_POST and $_GET or for some $option array that I send to function of class constructor.
