ID: 28503 Updated by: [EMAIL PROTECTED] Reported By: tomas dot matousek at matfyz dot cz -Status: Verified +Status: Wont fix Bug Type: Scripting Engine problem Operating System: * PHP Version: 5CVS, 4CVS (2005-06-19) New Comment:
In general, I suggest you initialize arrays with $arr = array();. This behavior is for backwards compatibility which comes from the early PHP 3 and PHP 4 days (before we had NULL and false). The old empty_string mapped to this and we had to keep behavior so as not to break large amounts of applications. However, you shouldn't be bumping into it especially as you are now aware that you should initialize your array()'s explicitly (or use undefined variables). Previous Comments: ------------------------------------------------------------------------ [2004-05-24 19:34:43] [EMAIL PROTECTED] I agree it's inconsistent, as it happens though it's being discussed already because of a related (but not identical) bug report: http://bugs.php.net/28476 ------------------------------------------------------------------------ [2004-05-24 11:21:26] tomas dot matousek at matfyz dot cz Sorry te "Actual result" should be reversed: Warning: Cannot use a scalar value as an array ... array(1) { [10]=> int(1) } ------------------------------------------------------------------------ [2004-05-24 11:18:46] tomas dot matousek at matfyz dot cz Description: ------------ Why does operator [] create a new array when applied on boolean FALSE and doesn't do so when applied on integer 0? One of that is IMHO wrong. Either this operator should create a new array on everything that is empty() or it should fail on all scalar types and make a new array only from empty string "" or NULL or uninitialized variable. Reproduce code: --------------- $a = 0; $a[10] = 1; var_dump($a); $b = false; $b[10] = 1; var_dump($b); Expected result: ---------------- Warning: Cannot use a scalar value as an array ... Warning: Cannot use a scalar value as an array ... Actual result: -------------- array(1) { [10]=> int(1) } Warning: Cannot use a scalar value as an array ... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28503&edit=1
