http_build_query给我获取相同名称的参数

Question

I'm sending multiple parameters to another page, and I am using http_build_query() to do this. The following code:

$array = array();

if(!empty($_POST['modelcheck'])){
    foreach($_POST['modelcheck'] as $selected){
        $array[] = $selected;
    }
}

$args = array
(
    'pricefrom' => $fromval,
    'priceto' => $toval,
    'model' => $array
);
    $params = http_build_query($args);
    $cleanedParams = preg_replace('/%5B(\d+?)%5D/', '', $params);


header("Location: ../page2.php?" . $cleanedParams);

gives me a url:

page2.php?pricefrom=10000&priceto=60000&model=1&model=2

As you can see model is repeated multiple times, I would like the parameters following the first model to be model2, model3.......etc.

I've tried putting it in a for loop:

for ($i=0; $i <count($array) ; $i++) { 
    $args = array
    (
        'pricefrom' => $fromval,
        'priceto' => $toval,
        'model'.$i => $array
    );
}

but this just gives me :

page2.php?pricefrom=10000&priceto=60000&model1=1&model1=2

Your $args variable should look like:

$args = array (
    'pricefrom' => $fromval,
    'priceto' => $toval,
    'model' => $array
);

UPD

Use preg_replace for replace html special chars if you want to use http_build_query with multiple params.

$query = preg_replace('/%5B(?:[0-9]|[1-9][0-9]+)%5D=/', '[]=', http_build_query($args));

You will receive an array by accessing to $_GET['model']
