Question

我正试图制作一个文字,从卢尔(url/?green&red&blue)获得所有钥匙。我知道我可以为此使用“GET”阵列,但我并不完全理解如何使用。

我要说的是,它使所有价值观都趋于一致,然后与它做一些事情,例如印刷。

I m stuck here right now so if anyone can help me further it will be much appreciated!

Answer 1

你们可以使用这样的东西:

foreach($_GET as $key => $value){
    echo "$key: $value<br />";
}

各位记得,你们应当使用户投入更加灵敏,因此在生产环境中不使用该守则。

Answer 2

foreach ($_GET as $key => $value){
  echo $key.  :  .$value. <br /> ;
}

Answer 3

Just to point out. if your url is (url/?green&red&blue)

你将获得这样的阵列。

   Array
   (
        [green] => 
        [red] => 
        [blue] => 
    )

Your url will need to look like this ( url/?colora=green&colorb=red&colorc=blue ) So you get:

   Array
   (
       [colora] => green
       [colorb] => red
       [colorc] => blue
   )

Answer 4

If you want to get them in javascript, here is the code snippet.

function getUrlVars()
{
    var vars = [], hash;
    var hashes = window.location.href.slice(window.location.href.indexOf( ? ) + 1).split( & );
    for(var i = 0; i < hashes.length; i++)
    {
        hash = hashes[i].split( = );
        vars.push(hash[0]);
        vars[hash[0]] = hash[1];
    }
    return vars;
}

The function returns an array/object with your URL parameters and their values.
