#15515 [Com]: Constructions involving "... or ..." don't work properly.

ID: 15515 Comment by: michaelaskew at mac dot com Reported By: jyoung187 at hotmail dot com Status: Bogus Bug Type: Compile Failure Operating System: RH Linux 7.2 (kernel 2.4.9-21) PHP Version: 4.0.6 New Comment: I'd like to second the motion to make this usage valid. I don't see anything in the manual that explains why this is invalid, but I'll conjecture that it has something to do with the keywords not returning a value, and I suppose the 'or' operator requires a value on its right hand side. I should think it would be easy enough to have the keywords return something so this becomes valid; after all, the expression 'or die ...' is valid and 'die' doesn't really have a return value.

In particular, I would very much enjoy the ability to do the following: isset($x) or return false; ($x > 0) or echo "failure"; empty($x) or break; ereg($x, $y) or continue; The ability to perform the four lines of code above would add greatly to the readability and clarity of PHP code. In the case of the "echo" statement, I am aware that print() function works instead, but would still enjoy the use of the echo construct in that fashion. ------------------------------------------------------------------------ [2002-06-18 19:24:43] sniper@php.net Thank you for taking the time to write to us, but this is not a bug. 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 ------------------------------------------------------------------------ [2002-02-15 13:01:35] sander@php.net This is a dupe... I'm sure I read a bug about this before, but I can't find it... Anyway, 'or return' doesn't. ------------------------------------------------------------------------ [2002-02-11 21:44:24] jyoung187 at hotmail dot com Script: <?php function foo() { $result = mysql_query("SELECT 1") or return false; //fails print("foo") or return false; // fails print("foo") or return 0; // fails print("foo") or return(false); // fails $result = mysql_query("SELECT 1") or die(); // works } ?> This bug seems to be present in PHP versions 4.0.6, and 4.2.0 - it's been tried on more than one machine (including two that I haven't installed myself). Essentially, constructions involving <expr1> or <expr2>, where expr2 is a keyword (return, continue, break, etc) fail with a parse error, whereas constructions where expr2 is a function (such as die() etc) succeed. This bug is not specific to the "or" keyword, either. It also occurs with the "and" keyword. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15515&edit=1
