From manual page:
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.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at and the instructions on how to report
a bug at

array_search() checks for loose equality by default, and 0 == null.

Use the $strict parameter.

I see, it was a lack of confirmation on my part.
Using the $strict parameter worked well.
Thank you very much.

what about use the third param and set it to TRUE to avoid type juggling
