Read a file, extract and echo some information

Hi all, I have a little dilemma on my hands that I can't seem to solve. Iv'e looked through the PHP Manual at the fread(), fgets(), fopen(), file() etc functions which I beleive are capabile of what I want to do, but I just can't seem to peice it all together. Anyway, the following code is inside of home.php: <?php $title = "Home page of the website"; ?> <p>Welcome to the home page of our website.</p> <p>Blah, blah and more blah!</p> And the following code is inside of index.php: <html> <head> <title><?php echo $title; ?></title> </head> <body> <?php require("home.php"); ?> </body> </html> As you can see, the above code will not work as the $title variable has not been set yet. So, I need a way of opening up the home.php file, extracting the line containing the $title variable and putting that information inbetween the <title></title> tags. Any ideas greatly appreciated, Thanks!
