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

ID: 42007 Updated by: jani@php.net Reported By: adrian dot gheorghe at gmail dot com Status: Open -Bug Type: Unknown/Other Function +Bug Type: Documentation problem Operating System: Windows XP Sp2 PHP Version: 5.2.3 New Comment: Documentation shouldn't say it's equivalent to regex matching when it really isn't..docs need update, the function is fine as is. Previous Comments: ------------------------------------------------------------------------ [2007-07-16 10:54:07] adrian dot gheorghe at gmail dot com 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 this bug report at http://bugs.php.net/?id=42007&edit=1
