将php变量插入我的html网址

Question

Hi I am trying to add my php variable $remove into the query string so that when the submit button is pushed the action that happens is a request made to remove_friend_db.php?user= where user = contained the value of $remove.

while ($row = $result->fetch_row())
{
    echo "<img src='images/$row[0]_thumb.jpg' atl='userThumbnail'>";
    echo "$row[1] $row[2] $row[3]";
    $remove= $row[0];
    ?>
    <form method="GET" action="remove_friend_db.php?remove="<?php "$remove">"">
    <input type="submit" value="Remove Friend">
    </form>
    <?php
}

<?php echo $remove ?>... You're not outputting anything. you're just basically saying "here's a variable" and php's going "ok, whatever".
