Writing Variables to File

Helios

I have a system in which visitors submit their reviews to my website. Using a form, their ratings on a scale of one to ten are inserted into a PHP file, which might look like this:

<?PHP
$sound="10";
$graphics="8";
$overall="8";
?>

I then use a different page to require() the file containing their review. However, I wish to automate this by making the form script write the coding above into a file and CHMOD to 0755. I know how to CHMOD existing files and create files and everything, but how do I get $sound or any other variable into a document without the server parsing it? For instance, it parses the $sound, $graphics, and $overall variables so that the file to be required looks like this:

<?PHP
="10";
="8";
="8";

I know this is possible because a message board script called PBLang does it many times. (For the record, the problem is not with CHMOD. A lot of people seem to think it is...)

You must backslash the $ like \$sound="10";

Actually, I found a solution before I read your reply. Here's what I did:

Instead of having $content="$sound=\"10\";\n"; and so on, I used $content="$"."sound=\"10\";\n"; which then prevented $sound from being parsed as it was written to the file, but it still wrote $sound as it was supposed to be. Thanks for the tip, though. I appreciate the help.

You could also have used single quotes:

$content='$sound="10";';

'xcept you wouldn't have the newline character on the end (but do you need it?)
