Question

I have a php page as below:

$sql = "select code as ref, size from product";

$result = mysql_query($sql);

    while($rs=mysql_fetch_assoc($result)){

        $test[] = $rs;
    }

$output['data'][] = $test;

echo json_encode( $output );

This ouputs the following:

{"data":[[{"ref":"ABC","size":"Large"},{"ref":"123","size":"Medium"}]]}

I need to modify the php, so that I can prefix some characters before the ref value so eg:

ref: ABC should be M-ABC

and

ref: 123 should be M-123

Finally I would also like to add an additional item to the array such as description and this will have a fixed description such as “This product is available in Large” (The value is based on the size).

Thanks

Answer 1

while ($rs = mysql_fetch_assoc($result)) {
    $rs['ref'] = "M-$rs[ref]";
    $rs['description'] = "This product is available in $rs[size]";
    $test[] = $rs;
}
