Bug #77845 [Com]: Error in the comparaison

Edit report at https://bugs.php.net/bug.php?id=77845&edit=1 ID: 77845 Comment by: a at b dot c dot de Reported by: baklouti dot med at gmail dot com Summary: Error in the comparaison Status: Not a bug Type: Bug Package: *Compile Issues Operating System: ubuntu 18.04 PHP Version: 7.2.16 Block user comment: N Private report: N New Comment: I didn't understand that last part. More useful for use would be a complete example that we could run that demonstrates your issue. The bug reporting form offers space for you to enter such a "test script". The code you have provided does not demonstrate your problem because if $id===0 then the second line of your code will cause "return 1;" to be evaluated and the switch will never even be reached. Previous Comments: ------------------------------------------------------------------------ [2019-04-04 14:50:44] baklouti dot med at gmail dot com ok switch works so fine, you can test it if you are so sure and tell us the result, because when id in the array test contains 0, the $is =0, and even test it with var_dump, and gettype to be sure before post this, thank you. ------------------------------------------------------------------------ [2019-04-04 14:37:14] spam2 at rhsoft dot net hell post the code you are actually using instead f**g decriptions ike " am not using the two cases in the same time" - switch works, full stop, echo what $id contains really at that moment ------------------------------------------------------------------------ [2019-04-04 14:34:18] baklouti dot med at gmail dot com Yes, I try it with "case 0:" , and the same issue is happening. ------------------------------------------------------------------------ [2019-04-04 11:21:37] kalle@php.net Because ($id === 0) is evaluated as an expression before, meaning that essentially the case statement now looks like case 1:. The correct way to do that which you are trying to would be to make your case statement simply look like case 0:. Please refer to the documentation int the future: https://www.php.net/manual/en/control-structures.switch.php ------------------------------------------------------------------------ [2019-04-04 11:10:25] baklouti dot med at gmail dot com Description: ------------ I am testing the value of $id to do some processing. I retrieve the variable $id from an array ($test) and converted to integer, for the case that $id = 0 when using "switch" it can't be detected and if I used the "if" it is working fine. I tried with the "==" and the "===" and also not working with "switch". I am not using the two cases in the same time, i tested the "if" and "switch" separately. $id = (integer)$test['id']; if ($id === 0 ) {return 1;} switch ($id) { case ($id === 0): return 2; .... Expected result: ---------------- The expected result is the bloc inside the case ($id ===0) is processed. Actual result: -------------- The actual result that it is passed for another case. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77845&edit=1
