Writing to a file.

[Nasimov]

It's possible to ammend data within a file vs. just adding data to the beginning or the end of the file? Mean to change something in the "middle" of the file.

Thanks.

Yes, you can, I'd do something like this:
$s_fdat = file_get_contents('thefile');

$s_fdat = str_replace("search","replace",$s_fdat);

$fp = fopen('thefile','w');
flock($fp,2);
fwrite($fp,$s_fdat);
fclose($fp);
