note 42242 added to language.variables

I'm having the following problem: In a database, I have the string "Welcome [username]". In another file, I have the following: "[username],$_SESSION["username"]". I use the following code (after reading the file as an array into $searchreplace): foreach ($searchreplace as $line) { list($search[], $replace[]) = explode(",", $line); } How can I have $replace = the value of $_SESSION["username"]?? If I echo both $search and $replace, the following is outputed: [username] $_SESSION["username"] I need to have $_SESSION["username"] replaced with the actual value of the variable. ---- Manual Page -- http://www.php.net/manual/en/language.variables.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+42242 Delete -- http://master.php.net/manage/user-notes.php?action=delete+42242&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+42242&report=yes Search -- http://master.php.net/manage/user-notes.php
