#32522 [NEW]: String offsets REALLY weird

From: php at alterego dot dp dot ua Operating system: FreeBSD 4.10 PHP version: 5.0.3 PHP Bug Type: Strings related Bug description: String offsets REALLY weird Description: ------------ Strings offsets in PHP5 are broken strangely. Seems like repeated offsets are not allowed at all, even at the times where they make good sense. I see nothing fatal in $a[0][0] or even $a{0}{0} or even $a[0]{0}[0] if $a is a non-empty string. And PHP5 just crashes at any one of them. Why $a{0} can't be a string without extra intermediate assignment? Please, look at the code before marking bogus. Reproduce code: --------------- <? $a = '0'; $b = $a[0]; echo $b[0]; $a = '0'; // leave any one line of the next few echo $a[0][0]; echo $a[0]{0}; echo $a{0}{0}; echo $a[0]{0}[0]; ?> Expected result: ---------------- 00 Actual result: -------------- 0 Fatal error: Cannot use string offset as an array in /www/test.php on line 8 -- Edit bug report at http://bugs.php.net/?id=32522&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32522&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32522&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32522&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32522&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32522&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32522&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32522&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32522&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32522&r=support Expected behavior: http://bugs.php.net/fix.php?id=32522&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32522&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32522&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32522&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32522&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32522&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32522&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32522&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32522&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32522&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32522&r=mysqlcfg
