<?php
$fileArray = file ("yourfilehere");
$fileLineCount = count ($fileArray);
$fileString = "";
for (i = 3 ; $i < $fileLineCount ; $i++)
$fileString .= $fileArray["$i"];
or
for (i = 3 ; $i < fileLineCount ; $i++)
$fileArray2["$i-3"] = $fileArray["$i"];
?>
Not the best method, but i didn't came up with a better one :}
