URL to Array in PHP

Question

I don't know how to make this working. I want to make arrays from URL:

index.php?address=someaddress&telephone=12345&customer=Customer Name&p_name[0]=ProductOne&p_name[1]=ProductTwo&p_price[0]=1&p_price[1]=10&p_name[2]...

There is an api, which is working like this:

$api‐>addItem(array(
        'name' => 'ProductOne',
        'price' => '123',
    ));

$api‐>addItem(array(
        'name' => 'ProductTwo',
        'price' => '32',
    ));

Is there any way to make arrays like this (=api request $api->addItem(array) from the URL? $api‐>addItem(array can be used multiple times.

Are there really $ in the URL? Are those supposed to be &? — gen_Eric

EDIT: Thanks dqhendricks and Rocket for pointing out that you can use parse_str() to do the same thing.

$q = parse_str(parse_url($url, PHP_URL_QUERY));

Or you could use this (the long way):

function parse_query($var) {
   $var = parse_url($var, PHP_URL_QUERY);
   $var = html_entity_decode($var);
   $var = explode('&', $var);
   $arr = array();

   foreach($var as $val) {
     $x = explode('=', $val);
     $arr[$x[0]] = $x[1];
   }
   unset($val, $x, $var);
   return $arr;
}

Use like this:

$url = "http://someurl.com/click?z=26&a=761";
print_r(parse_query($url));

Do you have control over the URL? If so, I'd change how you send your values.

Instead of:

name1=ProductOne&price1=123&name2=ProductTwo&price2=32

I'd use:

name[]=ProductOne&price[]=123&name[]=ProductTwo&price[]=32

The [] turn them into arrays, meaning $_GET['name'] is now an array. then you can foreach over it.

foreach($_GET['name'] as $k=>$v){
    $api->addItem(array(
        'name' => $v,
        'price' => $_GET['price'][$k]
    ));
}

Yes, I have full control over the URL. I think your code is what I exactly need, I am going to try it.

hmm, I can't make it working bit.ly/KuQ4H8. So the only way is parse_str&parse_url? The problem with that, there will be additional elements in the URL, which will be not in this array. I update the question.

@Adrian: What's the problem you're having?

Adrian Over a year ago

The array in the URL must be p_name[0], p_name[1]... I can't make array like this p_name[]. index.php?address=someaddress&telephone=12345&customer=Customer Name&p_name[0]=ProductOne&p_name[1]=ProductTwo&p_quantity[0]=1&p_quantity[1]=1

@Adrian: ...What's the problem? You can put values inside the [], but you don't have to. It'll work either way.

// extract the query from the url string
$url = parse_url('sample.php?name1=ProductOne&price1=123&name2=ProductTwo&price2=32', PHP_URL_QUERY);
// process into array so that first element is a key, and second element is a value
parse_str($url, $output_array);
// now $output_array contains the query's variables.

The bigger question is why would you want to do this when these variables are already contained in $_GET?

sample.php?name[]=Product1&name[]=Product2

Then in your PHP, you can see:

print_r($_GET['name']);

I'm not sure if I understood you right, but if what you're looking for is converting a querystring to an array you can user the pares_str function. in order to get only the querystring from a url you can use the parse_url function

$url = "sample.php?some_var=someval&s=4&bla=bla";
$url_parts = parse_url($url);
$qs = $url_parts["query"];
$params = array();
parse_str($qs,$params);
var_dump($params);

Like dqhendricks suggested, would it not pay to just use the raw gets and then append them to an array. I am assuming that you will always know what will be in the URL

$array_of_gets = array("address" => $_GET['address'],"telephone" => $_GET['telephone']);

and so on...
