如何使用PHP / HTML在循环中创建不同的提交操作

<table>
<?php   
    $ft = fopen("b.txt", "r");
    if (!$ft) {
        print "No accounts";
    } else {
        $data=file("b.txt");

        foreach ( $data as $line ) {
            $line=rtrim($line);
            list($a, $b, $c, $d, $e, $f, $g, $h, $i, $j, $k)=explode("\t",$line);

            echo "<tr><th>$a</th><th>$g</th><th>$b</th><th>$h</th>";
            echo '<form action="check1.php" method="post">
                  <th><input type="submit" value="Decline" name="Edit"></th>
                  </form></tr>';
        } /*END foreach*/

    } /*END if else*/ ?>
</table>

The b.txt contains:

 a     lbc     LA   0942455214     0942455214     2@email.com   23    412      09521266      w@emil.com    4444-02-13   
 ako   fedex   LA   092746421415   092746421415   A@email.com   ala   fornia   09865432478   a@email.com   2004-04-23

This will display a two-row table in a form of HTML, and in the end of the row there is a decline button (see image below).

The question is, where should I put this:

   if (isset($_POST['Edit'])) {
       $delete = $a;
       echo $delete;
   }

so that if I click the first decline button, it will display "a", and if I click the second one it will display "ako"?

Use <button> instead of submit, then try something like this:

 echo '<button type="submit" value="' . $a .'" name="btnDecline">DECLINE</button>'

if(isset($_POST['btnDecline']))
{
   $delete = $_POST['btnDecline'];
   echo $delete;
}
