Why is Refresh happening?

Question

PHP

I make a conclusion of all groups from the database, when you click on the name of the group, it goes to the group, and then Refresh happens, to the main one.

$q = mysql_query("SELECT `id`,`groups_name` FROM `groups`");
while($r = mysql_fetch_array($q)){
$id_q = <<<TXT
$r[id]
TXT;
$name = <<<TXT
$r[groups_name]
TXT;
echo<<<TXT
    <table border=1>
        <tr><td><a href="index?p=$id_q">$name </a> <br> <img width="120" src="$small_ava"><br></td></tr>
        </table>		
TXT;

Answer 1

Replace
with
"?p=$id_q"
