#22141 [NEW]: str_replace hangs with extra argument

From: arlo@typea.net Operating system: Mac OS 10.2 PHP version: 4.2.3 PHP Bug Type: Scripting Engine problem Bug description: str_replace hangs with extra argument I was inadvertently including a fourth argument of "-1" with some instances of str_replace() -- since I got into the habit of the limit arg using preg_replace() -- and I noticed an odd behavior: str_replace("-embed-a-", "hey", "-embed-a-", -1) returns "hey," as expected. str_replace("-embed-a-", "hey", "-embed-b-", -1) returns "embed-b-," as expected. But str_replace("-embed-a-", "hey", "-embed-aa-", -1) hangs the script until the max execution time. Removing the extraneous argument made my script work properly, but I would expect PHP to either ignore the extra argument, or return an error, rather than hanging up completely. -Arlo -- Edit bug report at http://bugs.php.net/?id=22141&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=22141&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=22141&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=22141&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=22141&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=22141&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=22141&r=support Expected behavior: http://bugs.php.net/fix.php?id=22141&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=22141&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=22141&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=22141&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=22141&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=22141&r=dst IIS Stability: http://bugs.php.net/fix.php?id=22141&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=22141&r=gnused
