php array remove value if exists
Just in case you want to use any of mentioned codes, be aware that array_search returns FALSE when the "needle" is not found in "haystack" and therefore these samples would unset the first (zero-indexed) item. Use this instead: <?ph, if (($key = array_search($del_val, $messages)) !== false) unset($messages[$key]); }. array_search() returns the key of the element it finds, which can be used to remove that element from the original array using unset() . It will return FALSE on failure
