#35841 [NEW]: PHP Does not like underscores?

From: maarten at kleeszone dot be Operating system: Linux2.6.12-1-amd64 Debian PHP version: 5.1.1 PHP Bug Type: Compile Failure Bug description: PHP Does not like underscores? Description: ------------ Recently I installed a new server with apache2, PHP5.1 and mysql 5.0.16 Now I noticed that sometimes (0.5% of all requests) I get fatal errors: Fatal error: Unknown function: strtomower() in /var/www/global/init.global.php on line 235 Fatal error: Unknown function: strtlower() in /var/www/global/init.global.php on line 235 Fatal error: Unknown function: arrayslice() in /var/www/global/init.global.php on line 105 Fatal error: Unknown function: classexists() in /var/www/global/init.global.php on line 259 Typo I tought, but there are no typo's at these lines and after refreshing the page, there is no error! (these lines are executed each time the script runs!). I get these errors sooner or later on every page. But everytime the error is gone after a refresh. Maybe some encoding problems? I save my pages as UTF-8. But in that case I would expect to see the error every request and not just 'sometimes'. -- Edit bug report at http://bugs.php.net/?id=35841&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=35841&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=35841&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=35841&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=35841&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35841&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35841&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35841&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35841&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35841&r=support Expected behavior: http://bugs.php.net/fix.php?id=35841&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35841&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35841&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35841&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35841&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35841&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35841&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35841&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35841&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35841&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35841&r=mysqlcfg
