From: dragos at codersnest dot com Operating system: fedora 6 PHP version: 5.2.6 PHP Bug Type: Unknown/Other Function Bug description: ctype_digit not validating int values Description: ------------ When passing an integer to ctype_digit, it will fail validating it. I tested several times, looks like this behaviour is consistent, I also tried using ctype_digit(65) which will also return "false". The PHP version is actually 5.1.6, running on Fedora 6 x86_64 with Apache 2.2.6 , all installed from the Fedora Repository. Same behaviour successfully reproduced with PHP 5.2.5 + Apache 2.0.54 on Suse9 x86_64. Possibly somewhere when the parameter passed is cast to a string, the value is somehow corrupted. Reproduce code: --------------- function getm($width, $height) { $errors = array(); if (!ctype_digit($width) || (int)$width <=0 ) { $errors[] = 'Width must be a positive integer value, ' . gettype($width) . ' passed'; } if (!ctype_digit($height) || (int)$height<=0 ) { $errors[] = 'Height must be a positive integer value, ' . gettype($height) . ' passed'; } return $errors; } $a = getm(48, 65); var_dump($a); Expected result: ---------------- array (0) {} Actual result: -------------- array(1) { [0]=> string(55) "Height must be a positive integer value, integer passed" } -- Edit bug report at http://bugs.php.net/?id=45710&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45710&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45710&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45710&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45710&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45710&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45710&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45710&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45710&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45710&r=support Expected behavior: http://bugs.php.net/fix.php?id=45710&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45710&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45710&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45710&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45710&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45710&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45710&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45710&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45710&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45710&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45710&r=mysqlcfg
