JSON Parsing with PHP

I’m hoping for a little assistance on this. I trying to take what’s in my $data variable:

[{"Product":"Internal",
  "Rank":"1",
  "Number":"1234"},
 {"Product":"External",
 "Rank":"1",
 "Number":"5678"}]

and turn it into an associative array that is something like this:

Product[0] => Internal,
Rank[0] => 1,
Number[0] => 1234,
Product[1] => External,
Rank[1]  => 1,
Number[1] => 5678

The closest I’ve been able to get is using the following code:

$del='/[{: ,}]/';
$data = preg_split($del,$data);
print_r($data);

Which gives me something like this:

Array ( [0] => [ [1] => “Product” [2] => “1 [3] => 1” [4] => “Rank”
[5] => “1”

Any suggestions would be greatly appreciated. Thanks for your time!

If you know that $data is in JSON format, you could just do this:

$data = json_decode($data);

Then you want to iterate through the array of objects and transmogrify them:

$output = array();
foreach($data as $index=>$object) {
    foreach($object as $name=>$value) {
        $output[$name][$index] = $value;
    }
}
