Array to String Conversion not working

Recommended Posts


Hello everyone,


A simple function is giving me a headache. Maybe someone can clarify what the problem is:


function count_all_stores_by_local_city($loc,$cit){
        global $connection;
        $query = "SELECT COUNT(*) FROM tbl_stores WHERE id_local = {$loc} AND id_city = {$cit}";
        $count = mysqli_query($connection,$query);
        return $count;





            $local = $_POST["local"];
            $city = $_POST["city"];
            $result_set = find_all_stores_by_local_city($local, $cit);
            $count = mysqli_fetch_assoc(count_all_stores_by_local_city($local, $city));
    <h2>Stores Found: <?php echo $count; ?> </h2>

I understand the $count is an object, a print_r gives me the result, but not in the desired format. What to do? It seems something so simple but I think I'm not seeing the point.


Thanks in advance!

Are $loc and $cit numeric or string values?


If strings, they need to be in single quotes within the query.


You also need to check if the query failed or not. ($count will be 'false' if it failed. If so, check the error message value.


Avoid embedding function calls within function calls - it prevents you from error checking.


After calling the function, $count is an array. The value you want will be in the first element. Use a column alias in the query when using sql functions eg

SELECT COUNT(*) as total FROM ...
then it's easy to reference the required array element as $count['total']. Edited by Barand
