ID: 25566 Comment by: shadowfaxx at cc dot com Reported By: Jared dot Williams1 at ntlworld dot com Status: Open Bug Type: Scripting Engine problem PHP Version: 4.3.3 New Comment:
To add to the above, it seems that the '0' case is the culprit. If you use the code below where '10' replaces '0', the weird behavior does not occur: $t = array(10,1,2,3,'*','+','a', 'b'); foreach($t as $v) switch ($v) { case 10: echo('0'); break; case 1: echo('1'); break; case 2: echo('2'); break; case 3: echo('3'); break; case '*': echo('*'); break; default: echo($v); break; } OutPut: 0123*+ab So it seems that Case 0: grabs all the cases which are of a different data type if the case expressions are not of the same type i.e. numeric and string.

If all case expressions are of the same type, either numeric, or string, this problem does not arise. It is not clear why, or really what type the switched expression is cast to before comparision. Reproduce code: --------------- $t = array(0,1,2,3,'*','+','a', 'b') foreach($t as $v) switch ($v) { case 0: echo('0'); break; case 1: echo('1'); break; case 2: echo('2'); break; case 3: echo('3'); break; case '*': echo('*'); break; default: echo($v); break; } Expected result: ---------------- 0123*+ab The first 5 array elements are output their respective case statements, and the latter 3 are handled by the default case. Actual result: -------------- 01230000 The first 5 array elements are output their respective case statements, and the latter 3 are handled the 0 case. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25566&edit=1
