$_GET key == value?

[Hailwood]

Hi guys,

 

 

If i have a url such as

www.example.com?41

how do i get the 41?

 

 

I ak as this is what i am passed from another site, so i do not know the actual value.

 

 

I came up with:

 

 

foreach($_GET as $k => $v)
    $id = $k;
echo $id;

 

 

but it is rather inefficient.

 

 

any ideas?

the 41 should have a variable assigned to it like

 

?page=41 or whatever name you want

 

the you would use $_GET['page'];

[Hailwood]

yeah,

I have no control over how they pass it to me,

and this is the method they have chosen to use.

With no actual named variable

Thanks though.

 

 

Any more ideas?

Could you post a link to the method you have used because this sounds unusual?

Method I have used for what exactly?

The 41 is coming from another site (not controlled by me)

 

My job is to simply fetch it.

well if your going for efficiency:

 

If this is the definite format, with a single argument, no assignment, then this is your code:

$_SERVER['QUERY_STRING'];

 

-cb-

 

On a side note, if you know its to be a number, but the length of digits and number of arguments may vary then something like this should be pretty efficient:

preg_match("/^[0-9]+/",$_SERVER['QUERY_STRING'],$match);
$number = $match[0];

Of Course, only if you know it will be the first argument .

 

-cb-
