You're using the file_get_contents function incorrectly.
The following line:
$contents = file_get_contents($filename);
Is equivalent to the following lines:
$handle = fopen($filename,"r");
$contents = fread($handle,filesize($filename));
fclose($handle);
The "Cannot modify header information" errors are just errors that
follow due to the fact that the first error already has sent headers
back to the client in order to be displayed.
