I have a PHP page that will be sent (via GET) a variable number of variables with the same name.

i.e.

&color=Blue&color=Green&color=Black etc.

Is there an easy way to iterate through these?

I dont think without using array you cant retrieve data of same name. Example 

<input type="text" name="color[]" value="blue"> <input type="text" name="color[]" value="green"> <input type="text" name="color[]" value="black">

now datas will pass like this 

?color[]=Blue&color[]=Green&color[]=Black $color=$_GET['color']; print_r($color); Array ( [color] => Array ( [0] => Blue [1] => Green [2] => Black ) )

For a variable number of "grouped" values, you can use a query string like this:

?color[]=Blue&color[]=Green&color[]=Black

and you'll get an array in your $_GET:

print_r($_GET); Array ( [color] => Array ( [0] => Blue [1] => Green [2] => Black ) )
