#25725 [NEW]: highlight_string doesn't parse strings containing \ properly

From: kjartan at zind dot net Operating system: Linux + Windows PHP version: 4.3.3 PHP Bug Type: Unknown/Other Function Bug description: highlight_string doesn't parse strings containing \ properly Description: ------------ Given a string that contains this PHP code: <?php $a = 2; \; $b = 3; ?> Then highlight_string() generates this: <?php $a = 2; Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /home/kjartan/scripts/highlight_string on line 9 ; $b = 3; ?> Granted its not valid PHP, but should hightlight_string() function as a PHP validation system? Not that it does a good job at it as this gets colored just fine: <?php $a = 2 $b = 3 $c = 5 ?> What gives? Reproduce code: --------------- <?php $string = '<?php $a = 2; \ $c = 5; ?>'; highlight_string($string); Expected result: ---------------- I expect it to just leave the \ alone and not cause warnings. -- Edit bug report at http://bugs.php.net/?id=25725&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25725&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25725&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25725&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25725&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25725&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25725&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25725&r=support Expected behavior: http://bugs.php.net/fix.php?id=25725&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25725&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25725&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25725&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25725&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25725&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25725&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25725&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=25725&r=float
