Question

In php I have the following array:

$car[] = array ("id"=>"1", "brand"=>"Audi", "price"=>"7000"); 
$car[] = array ("id"=>"9", "brand"=>"Merc", "price"=>"9000");

With this array I would like to build the following query string:

&brand0=Audi&brand1=Merc&id0=1&id1=9&price0=7000&price0=9000

How can I go about doing this?

Please note that the array may have more results than just the 2 rows, and so that the built querystring should be able to cope with it (also the results being used in this example may vary).

Thanks

Answer 1

$params = array();
for($i=0;$i<count($car);$i++) {
    $params[] = 'id' . $i . '=' . $car[$i]['id'];
    $params[] = 'brand' . $i . '=' . $car[$i]['brand'];
    $params[] = 'price' . $i . '=' . $car[$i]['price'];
}
$string = implode('&', $params);

This will go through, and create the keys with the number on them, and then glue it all together at the end to give you the $string that you were wanting. It will also, just for cleanliness, not have an extra & at the start or end that you might get if you simply append.
