Count Similar Array Keys

Question

I have a POST request coming to one of my pages, here is a small segment:

[shipCountry] => United States
[status] => Accepted
[sku1] => test
[produc

As mentioned by gumbo you could group all parameters describing one item in its own array which usually makes it easier to iterate them. You may not have control over the POST parameters but you can restructure them like e.g. with

 'United States',
  'status' => 'Accepted',
  'sku1' => 'test1',
  'product1' => 'Test Product1',
  'quantity1' => '1',
  'price1' => '0.01',
  'sku2' => 'test2',
  'product2' => 'Test Product2',
  'quantity2' => '2',
  'price2' => '0.02'
);

$pattern = '/^(.*\D)(\d+)$/';
$foo = array('items'=>array());
foreach($testdata as $k=>$v) {
  if ( preg_match($pattern, $k, $m) ) {
    $foo['items'][$m[2]][$m[1]] = $v;
  }
  else {
    $foo[$k] = $v;
  }
}
print_r($foo);
