small help with mysql php

Project Title: Optimize MySQL Query Performance I am looking for a freelancer who can assist me with my MySQL query performance. Specifically, I need add a extra sql line. I think mysqli is needed but i am not sure. Specific Task: - let the script workin as is now does but i need select "spelnummer" where spelersnaam is the one that is "Get" from the previous page. Queries 1 (that works already, expect the $spelnummer part for the location) <?php require_once("[login to view URL]"); $spelersnaam = $_GET['spelersnaam']; if((isset($_GET['spelersnaam']) !='')) { $spelersnaam = $conn->real_escape_string($_GET['spelersnaam']); $sql = "UPDATE spelers SET actief='1' WHERE spelersnaam = '".$spelersnaam."'"; if(!$result = $conn->query($sql)){ die('There was an error running the query [' . $conn->error . ']'); } else { $website = "[login to view URL]$spelnummer"; header("Location: $website"); } } else { echo "Please fill Name and Email"; } ?> Query 2: As said Query2 that needs to be combined should select spelnummer from spelers where spelersnaam = $spelersnaam (so that it can be used in this part $website = "[login to view URL]$spelnummer";) Ideal Skills and Experience: - Expertise in MySQL and PHP - Experience with query optimization If fixed quick and good then i have more small website / html / css / php/msql things.
