Can this be done?

[Ken]

How do I save the values (not variables) for the variables in a file?

Example:
$_SESSION['category'] = "TEST";
$url_read = readfile.php;
$url_write = writefile.php;

$sort = "var ".$_SESSION['category'];

// read file
$f_r = file($url_read) ;
$read_file = fopen($url_read , "r");

// write to file
$f_w = file($url_write );
$write_file = fopen($url_writ e, "wb");

$key="sort";
foreach($f_r as $line) {
$sorte = strstr($line, $key); //look for $key in each line
fwrite($write_f ile,$sorte);
}
fclose($write_f ile);
fclose($read_fi le);

The results of the above in writefile.txt is sort = "var
".$_SESSION['category'];
In the writefile.txt, I am looking for: var TEST

I have tried several approaches with no results.

Thanks for the help.

Why are you setting this? You're not using it later.

Don't need the above line, you've already read the file.[color=blue]

Don't need the above line. Why are you reading in the file you're going
to be writing?

What does the variable $sorte contain here?

The above writes the value of $sorte to the file.

If you remove the fopen for $read_file, remove the above also.

What have you tried?

Tell us or show us what's in your input file. What do you expect to get
out as a result?
