PHP array keys

Those look like the same thing in a different display to me.  What is the actual problem?

I agree wid DaveBaldwin, you may not understanding the way the "array" And "SUB-arrays" are shown as relationshilps as child-parent arrays, , to me this -
[products[0][product_id]] => 1
    [products[0][price]] => 12.00
    [products[0][name]] => Product Name
    [products[0][product_qty]] => 1

is the same as your desired -
[product] => Array
      (
            [0] => Array
            (
                  [product_id] => 1
                  [price] => 12.00
                  [name] => Product Name
                  [product_qty] => 1
            )

you show the "Code work" version to get that array,and in seems to be the same as the analysis print out for the same thing.

in your jason decode array output try this
if ($jArray['product'][0]['product_id'] == 1) echo "First Product element for product_id is ONE";
and see if  the array is as you want it.

The top the key name is: [products[0][product_id]] and is not a multidimensional array.

OK, looks like I'm the one not understanding this?
to be certain , since I do not have this to test, you access it like
if ($jArray["products[0][product_id]"] == 1) echo "First Product is equal ONE";

if that's the case then you will likely need to loop through the whole json array and then build a new second separate array, by separating out the "product" and [systemNotes[1]] keys and then creating sub arrays in the new array and adding the values from the old array. You may could use the [ ] in the key name for a separator, but if there are more than a couple of Keys other than product and systemNotes it could take some time to get it all correct.

Hello ScotTFO,

If you can give your json part, it will help more to give you some proper solution.

Thank you.

+1 for what @amar_bardoliwala asks.  This is a data-dependent problem, and the easiest way to get help is for you to post the test data so we can replicate the issue and give you tested-and-working solutions.

OK, I remembered some string parse I did years ago to chop out user format in a bulletin board post using the [   as they use here in this EE post thing. Amazingly I found that code, and sloped together this, which to me does what you require, All I had to work wid was your JSON Array definition, which may be a shortened exert of the JSON thing?

This works for me on my server -

$jArray = array('name' => 'Name1', 'address' => '123 Street Rd', 'products[0][product_id]' => 11, 
    'products[0][price]' => 12.01, 'products[0][name]' => 'Product Name1', 'products[0][product_qty]' => 1, 
    'products[1][product_id]' => 22, 'products[1][price]' => 3.00, 'products[1][name]' => 'Product Name2', 'products[1][product_qty]' => 2,
    'systemNotes[0]' => 'Note 1', 'systemNotes[1]' => 'Note 2');
$modArray = array();
$newA = '';
$aNum = 0;
foreach ( $jArray as $key => $value ) {
$pos1 = strpos($key, '[');
    if (($pos1 === false) || ($pos1 < 2)) $modArray[$key] = $value;
      else {$pos2 = strpos($key, ']');
       if ($pos2 > $pos1) {
       $sb = substr($key, 0, $pos1);
      ++$pos1;
      if ($sb != $newA) {
        $newA = $sb;
        $sb = substr($key, $pos2+2,-1);
        $aNum = (int) substr($key, $pos1, $pos2-$pos1);
        if ($sb) $modArray[$newA][$aNum][$sb] = $value;
          else $modArray[$newA][$aNum] = $value;
       } else {
        $ne = substr($key, $pos2+2,-1);
        $sb = (int) substr($key, $pos1, $pos2-$pos1);
        if ($sb == $aNum) {
          $modArray[$newA][$aNum][$ne] = $value;
          } else {
          $aNum=$sb;
          if ($ne) $modArray[$newA][$aNum][$ne] = $value;
          else $modArray[$newA][$aNum] = $value;
           }
       }
     } else $modArray[$key] = $value;
  }
}

echo '<pre>';
print_r($jArray);
echo "\n= = = = = = = = = = =\n";
print_r($modArray);
echo '</pre>';

But this is a short on time effort for me, It is made specifically and only for the  KEY Strings of type format shown in your example, the first part of key -
products[0][product_id]
systemNotes[1]
as products and  systemNotes can be ANY string at least 2 characters long
the ARRAY brackets as  [2] MUST have only numbers, this will FAIL if there are non-number strings for the 2 part
any string characters past the first ] MUST be in brackets as  [product_qty], the brackets are removed and the string as "product_qty" is used as a KEY in a new sub array.
This is not so easy to do if the return JSON are not of a consistent KEY format and arrangement.
Ask questions if you need more info. I hope you are still responding here, post if you can.

@ScotTFO: Any progress on getting us that JSON string?  Thanks, ~Ray

The answer at https:#a39339897 produces this, which is exactly what the author asked for.

Array
(
    [name] => Name1
    [address] => 123 Street Rd
    [products[0][product_id]] => 11
    [products[0][price]] => 12.01
    [products[0][name]] => Product Name1
    [products[0][product_qty]] => 1
    [products[1][product_id]] => 22
    [products[1][price]] => 3
    [products[1][name]] => Product Name2
    [products[1][product_qty]] => 2
    [systemNotes[0]] => Note 1
    [systemNotes[1]] => Note 2
)
