note 79260 added to ref.mysql

David: In this line: $query = "SELECT username FROM users WHERE username REGEXP '$username[0-9*]'"; PHP may read $username[, *including* the open square bracket, and may think you are trying to get into an array. You should use this instead: $query = "SELECT username FROM users WHERE username REGEXP '${username}[0-9*]'"; Or maybe this: $query = "SELECT username FROM users WHERE username REGEXP '$username" . "[0-9*]'"; ---- Server IP: 190.2.55.3 Probable Submitter: 200.112.140.207 ---- Manual Page -- http://www.php.net/manual/en/ref.mysql.php Edit -- https://master.php.net/note/edit/79260 Del: integrated -- https://master.php.net/note/delete/79260/integrated Del: useless -- https://master.php.net/note/delete/79260/useless Del: bad code -- https://master.php.net/note/delete/79260/bad+code Del: spam -- https://master.php.net/note/delete/79260/spam Del: non-english -- https://master.php.net/note/delete/79260/non-english Del: in docs -- https://master.php.net/note/delete/79260/in+docs Del: other reasons-- https://master.php.net/note/delete/79260 Reject -- https://master.php.net/note/reject/79260 Search -- https://master.php.net/manage/user-notes.php
