PHP Tricks & Tips: PHP Script to variable

The following I found on a Usenet post on how to EASILY parse a PHP script’s output to a variable using output buffering:

Sounds like you could use buffering.
< ?php ob_start(); // Start output buffering. // Instead of outputting anything, the output is now stored in a buffer. include('yourfile.php'); // There, now the file has been included and php parsed. // It isn't output, it goes into the buffer. $yourfile = ob_get_clean(); // Now we read everything that has been buffered... And stops buffering. ?>
Result: the file you included has been parsed by the php engine and stored
inside $yourfil, and nothing was output. Sounds like goal achieved.
