#42007 [NEW]: ctype_alnum( int ) will return false

From: adrian dot gheorghe at gmail dot com Operating system: Windows XP Sp2 PHP version: 5.2.3 PHP Bug Type: Unknown/Other Function Bug description: ctype_alnum( int ) will return false Description: ------------ ctype_alnum returns false if you pass it an integer (ie 7). I know the docs say that it should receive a string, as all ctype_* functions should, but I believe it's pointless to have to do a ctype_alnum( '' . $var ) at every call just to be sure. Also, the docs say that the function is equivalent to preg_match('/^[a-z0-9]+$/iD', $text) and matching 7 against that expression will work. Reproduce code: --------------- var_dump( ctype_alnum( 7 ) ); Expected result: ---------------- bool(true) Actual result: -------------- bool(false) -- Edit bug report at http://bugs.php.net/?id=42007&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42007&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42007&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42007&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42007&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42007&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42007&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42007&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42007&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42007&r=support Expected behavior: http://bugs.php.net/fix.php?id=42007&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42007&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42007&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42007&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42007&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42007&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42007&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42007&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42007&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42007&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42007&r=mysqlcfg
