note 76302 added to function.ctype-alnum

When checking strings with multiple words for non alphanumeric characters ctype_alnum would consider space as non alphanumeric character as well. So to check a string with multiple words for non alphanumeric characters use str_replace foreach ($imported_queries as $check_aplhanum) { $check_aplhanum = str_replace (" ", "", $check_aplhanum); if (!(ctype_alnum($check_aplhanum))) { echo "Query string contains alphanumeric characters"; } } ---- Server IP: 203.16.234.19 Probable Submitter: 58.175.60.158 ---- Manual Page -- http://www.php.net/manual/en/function.ctype-alnum.php Edit -- https://master.php.net/note/edit/76302 Del: integrated -- https://master.php.net/note/delete/76302/integrated Del: useless -- https://master.php.net/note/delete/76302/useless Del: bad code -- https://master.php.net/note/delete/76302/bad+code Del: spam -- https://master.php.net/note/delete/76302/spam Del: non-english -- https://master.php.net/note/delete/76302/non-english Del: in docs -- https://master.php.net/note/delete/76302/in+docs Del: other reasons-- https://master.php.net/note/delete/76302 Reject -- https://master.php.net/note/reject/76302 Search -- https://master.php.net/manage/user-notes.php
