Re: I want to remove the last comma

What I would do is change var tinyMCEImageList = new Array(\n"; to have a space and then the newline character at the end like so var tinyMCEImageList = new Array( \n"; then change your last $out line $out .= ");\n"; to strip the last 2 characters (which always gets called) and closes the Array opening parenthesis. $out = substr($out, 0, -2) . ");\n"; And your Javascript will always be able to be parsed even if there are no elements in the array. http://php.he.net/manual/en/function.substr.php BTW, this is more of a general list question though, not a php-db question.
