PHP appending to file from specific position

Question

In php i am opening a text file and appending to it. However I need to append 3 chars before the end of file. In other words i need to append/write from a specific place in the file.

Can any one help?

You need to open the file for edit, seek to the desired position and then write to the file, eg.:

<?php
  $file = fopen($filename, "c");
  fseek($file, -3, SEEK_END);
  fwrite($file, "whatever you want to write");
  fclose($file);
?>

Further reference at php.net - fseek doc

Hope that helps.
