Bug #52650 [NEW]: Different result when using a number than a variable.

From: Operating system: Xp sp3 PHP version: 5.3.3 Package: Scripting Engine problem Bug Type: Bug Bug description:Different result when using a number than a variable. Description: ------------ When i put a direct number or variable in a for block, it works fine, but if i do an equation it fails. Even if it is very simple. Test script: --------------- <?php error_reporting(0); $index = "0"; $a = "0"; $b = "0"; //As you can see variable returns 1. echo ">" . ($a==$b) . "<" . "<br>"; // So... this should go from 1 to 10. // replace "($a==$b)" with 1 and everything works as it should. for ($index=($a==$b); $index<=10; $index++) { // this always prints 1. An endless loop. echo $index . "<br>"; } ?> Expected result: ---------------- >1< 1 2 3 4 5 6 7 8 9 10 Actual result: -------------- >1< 1 1 1 1 1 1 1 1 1 1 1 1 (infinite) -- Edit bug report at http://bugs.php.net/bug.php?id=52650&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52650&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52650&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52650&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52650&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52650&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52650&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52650&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52650&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52650&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52650&r=support Expected behavior: http://bugs.php.net/fix.php?id=52650&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52650&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52650&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52650&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52650&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52650&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52650&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52650&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52650&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52650&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52650&r=mysqlcfg
