[STphp]

To delete a line, just make a form with a text field in where users submit their email address or something and call the field 'email' and use this to remove the line from the file:

PHP Code:

<?php



$Lines = file("users.txt");

$cLines = count($Lines);

$dlete = $_POST['email'];



  foreach($Lines as $Key => $Val) { 



   $Data[$Key] = explode("|", $Val);



    if ( trim($Data[$Key][1]) == $dlete ) {



     unset($Lines[$Key]);

     $fp = fopen("users.txt", "w");

     $fw = fwrite($fp, implode('', $Lines));

     fclose($fp);



    }



  }



print "Deleted";



?>
