You’d be better off using a database because these operations can step on each other.. but:

Add:

$fp = fopen("list.txt","a");   //a is for append
fputs($fp,"[e-mail]" . "\n");
fclose($fp);

Remove:

$file = file_get_contents("list.txt");
unlink("list.txt");  //delete existing file
$fp = fopen("list.txt","w");   //w is for write/new
$lines = split("\n",$file);
while (list(,$email) = each($lines)) {
    if ($email != "[e-mail]") fputs($fp,$email . "\n");
}

Again… highly recommended to use a database… this is not optimal.
