Mike,

Thats easy enough, just explode it twice; once to break it up into the
grouplets, then to seperate the name / value pairs.

<?php

$incoming =
"prodCode=306045520&desc=10ft%20Fast-Set%20Pool&price=39.99&prodCode=3060940
10&desc=8ft%20x%208ft%20Jumbo%20Bouncy%20Castle&price=79.99&prodCode=3200106
70&desc=Cutting%20Edge%2018v%20Cordless%20Hedge%20Trimmer&price=23.99";

$wibble = explode("&",urldecode($incoming));
$i=0;
foreach($wibble as $value){$subwibble[$i] = explode("=",$value); $i++;}
print_r($subwibble);

?>

which will give you;

Array
(
    [0] => Array
        (
            [0] => prodCode
            [1] => 306045520
        )

    [1] => Array
        (
            [0] => desc
            [1] => 10ft Fast-Set Pool
        )

    [2] => Array
        (
            [0] => price
            [1] => 39.99
        )

    [3] => Array
        (
            [0] => prodCode
            [1] => 306094010
        )

    [4] => Array
        (
            [0] => desc
            [1] => 8ft x 8ft Jumbo Bouncy Castle
        )

    [5] => Array
        (
            [0] => price
            [1] => 79.99
        )

    [6] => Array
        (
            [0] => prodCode
            [1] => 320010670
        )

    [7] => Array
        (
            [0] => desc
            [1] => Cutting Edge 18v Cordless Hedge Trimmer
        )

    [8] => Array
        (
            [0] => price
            [1] => 23.99
        )

)

The [0] cells are pretty superflous but act as a mnemonic as to whats in [1]
I'd personally introduce a filter incase there might be an = or & embedded
anywhere in the incoming data - but these _should_ be coming through as html
entities.

If you cut and paste that into a test page watch that you dont get some
sneaky \n returns ending up in the data! :-)
