Using the $strict parameter worked well. Thank you very much.

Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php array_search() checks for loose equality by default, and 0 == null. Use the $strict parameter. ------------------------------------------------------------------------ [2020-05-11 06:14:45] yattyan83 at gmail dot com Description: ------------ --- From manual page: https://php.net/function.array-search --- I used array_search() to look at the beginning of the array and find the location of the first null.（In order to fill the array's nulls per request） But array_search() tests 0 as null. Try the example below. Test script: --------------- $array = [ 'a' => 1, 'b' => 0, 'c' => null, 'd' => null ]; echo array_search(null, $array);//expect c > b Expected result: ---------------- I would have liked to have gotten a C back if I could. You can also use foreach as an alternative, so please let me know if this is a spec or a bug. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79583&edit=1
