如何在我的php页面中插入函数而不是锚标记

Question

如何在我的php页面中插入一个函数而不是一个锚标记？

我的问题在于这一行：

echo 'Click <a href="add-calendar.php?fname='.$fname.'&lname='.$lname.'&sdate='.$startdate.'&edate='.$enddate.'&description='.$description.'&title='.$title.'">HERE</a> to add it on the calendar';

这是我的代码

$id = $_GET["id"];
$query = mysql_query("SELECT * FROM booking_members WHERE id='$id'");
while($row = mysql_fetch_assoc($query))

{


$id = $_GET["id"];
$querychange = mysql_query("UPDATE booking_members SET status='Paid',payment_status ='Paid' WHERE id = '$id'");

    $fname = $row['firstname'];
    $lname = $row['lastname'];
    $startdate = $row['start_date'];
    $enddate = $row['end_date'];
    $description = $row['description'];
    $title = $row['title'];

echo 'The Request has been approved. You may now go <a href="admin-panel.php?$id">Back to the previous page</a><br>';
echo 'Click <a href="add-calendar.php?fname='.$fname.'&lname='.$lname.'&sdate='.$startdate.'&edate='.$enddate.'&description='.$description.'&title='.$title.'">HERE</a> to add it on the calendar';
