This will cause $current to contain the number of bytes read from the
file, not the contents of the file.
http://www.php.net/readfile
Instead, use fopen()/fread(); or file()/implode(); or if you have PHP
4.3.x or newer, use file_get_contents().
http://www.php.net/file_get_contents
http://www.php.net/fopen
http://www.php.net/fread
http://www.php.net/file
http://www.php.net/implode

This will do two things you probably don't want: first, it will
repeatedly assign values to $index, overwriting it on each iteration;
and, it will always use the same value to do so, since
$HTTP_POST_VARS['$index'] has the single-quotes, which prevents PHP
from interpreting the contents of $index--so it's literally using the
string value '$index' instead of the value of the $index variable. You
probably want variable variables:
$$index = $HTTP_POST_VARS[$index];
...although even easier would be:
$$index = $value;
