ID: 55373 Updated by: [email protected] Reported by: computerboy0 at gmail dot com Summary: Unexpected behavior involving conditions. -Status: Open +Status: Bogus Type: Bug Package: Scripting Engine problem Operating System: OS X 10.5.8 (Irrelevant) PHP Version: Irrelevant Block user comment: N Private report: N New Comment: 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 Please see http://www.php.net/manual/en/language.operators.precedence.php && has a higher precedence than = so the result of that expression is correctly false. Previous Comments: ------------------------------------------------------------------------ [2011-08-06 01:44:24] computerboy0 at gmail dot com Description: ------------ Using IF or WHILE statements (possibly others?), the code below produces unexpected results. Test script: --------------- //Set a variable with an initial value. $TEST="Initial"; //Set the variable to a different value, then test for it. if($TEST="Secondary" && $TEST==="Secondary") echo "Expected result occurred."; else echo "Expectation FAIL"; //During the ($TEST==="Secondary") condition, $TEST should match "Secondary", having just been set to "Secondary". Instead, there $TEST is actually still "Initial". echo "\n".$TEST; Expected result: ---------------- $TEST should be set to "Secondary" within the IF statement and then reflect that within said IF statement. It does not seem to. Script result: Expected result occurred. Secondary Actual result: -------------- What actually happens is that $TEST only becomes "Secondart" *after* the entire IF statement has processed. So any following comparison with $TEST still yields its initial value. Script result: Expectation FAIL Secondary ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55373&edit=1
