Disabled code in strings?

[Sniffy]

I'm not sure if I should have put this in the PHP forum or not, but how do I process code but not execute it on my document?e.g

<?php$fN = "sFile.txt";$fH = fopen($fN, 'a');$fC = "if(my == 0){ //exec }";fwrite($fH, $fC);fclose($fH);?>

What do you mean by that? You want to write PHP code to a file? That's what your example shows.
