$_SERVER Problem

[tomwerner]

One simple question why does:

<?php

//This writes the data to the textfile
$filename = "weblog.txt";

//Opens the file
$open_file = fopen($filename, "a+");

$date = date(l);
$serveruser = "$_SERVER['HTTP_USER_AGENT']";
$serverrefer = "$_SERVER['HTTP_REFERER']";
$string = "$date : $serveruser : $serverrefer\n";
print($string);


fwrite($open_file, "$string");

//Closes the file
fclose($open_file);

?>

Print out Sunday : : ?

I am guessing that it isn't getting the $_SERVER variables, but why would it do this?

You should be getting a syntax error. You need to take the $_SERVER variables out of the double quotes.

Thanks, i'll take the double quotes out. I didn't get a syntax error because I have not turned errors on yet because I have only just reinstalled PHP.
