refresh another item shows up replacing the other. plz help and thanks

function get_list() {
 $id = mysql_real_escape_string(@$_GET['id']); 
$get_list = array();
$bar = mysql_query(" SELECT  bar.* FROM bar WHERE bar.b_id = '$id' ORDER BY rand()");
 while($kpl = mysql_fetch_assoc($bar)){
 $get_list[] = array( 'videoid' => $kpl['videoid'],
                'name' => $kpl['name'],
                'description' => $kpl['description'],
                'type' => $kpl['type'],
                'bev' => $kpl['bev'],           
);
}
foreach ($get_list as $get_list);
return $get_list;
}
?>
<?php
$gkp_list = gkp_list();
foreach ($gkp_list as $gkp_list);
if (empty($gkp_list)){ echo 'no video'; }
else { 
echo '<p>$gkp_list['name']. '<br/></p>';}
?>

There are some major syntax problems there.

function get_list() {
    $id = mysql_real_escape_string(@$_GET['id']); 
    $get_list = array();
    $bar = mysql_query(" SELECT  bar.* FROM bar WHERE bar.b_id = '$id' ORDER BY rand()");
    while($kpl = mysql_fetch_assoc($bar)){
        $get_list[] = $kpl;         
    }
    return $get_list;
}

$gkp_list = get_list();
if (empty($gkp_list)) {
    echo 'no video';
} else {
    foreach ($gkp_list as $gkp_item) {
        echo '<p>' . $gkp_item['name']. '<br/></p>';
    }
}
?>

1. The purpose of foreach is to loop over an array and do something with each value. Don’t use foreach if you’re working with the array as a whole (in this case, returning it)
2. Foreach doesn’t have a semicolon at the end, it typically has an opening curly brace ({).
3. You don’t need to manually copy all of the array indexes in the while loop, because all of the indexes are the same.
4. The string for the output was formatted wrong, you have to be careful. Use a syntax-highlighting editor.
5. The two variable names in foreach must be different. One refers to the array, and one refers to the value of that key.
