Thanks for you steps, i had a go at doing it..is this what you meant
by any chance?

<?php

$line = file ("./member.txt", "w");
unset($line);

$line = fopen("./member-new.txt");

unlink("./member.txt")

rename("member-new.txt","member.txt");

fclose($line);


?>

I am getting a parse error, and i am not sure if i am doing this
right??

Parse error: syntax error, unexpected T_STRING in /volumes/data1/home/
pioannou/public_html/php/Assignment11/admin/delete_member.php on line
