Echo data retrieved from query to a table PHP based on same value

Question

So I have this array that consists of

array (size=3)

  0 => 

   array (size=2)

    'id' => string '46' (length=2)

    'ship_product_code' => string '122' (length=6)

    'purchase_order_number' => string 'PO-1' (length=4)

  1 => 

   array (size=2)

    'id' => string '47' (length=2)

    'ship_product_code' => string '123' (length=6)

    'purchase_order_number' => string 'PO-2' (length=4)

  2 => 

   array (size=2)

    'id' => string '50' (length=2)

    'ship_product_code' => string '124' (length=6)

    'purchase_order_number' => string 'PO-2' (length=4)

I wanted to echo a table that is based on the Purchase Order Number. So by given above array, how can I create a table that is like following:

  PO-1 //PO Number

  122 // Product Code



  <tr> <td> </td> </tr>//another td for space 



  PO-2 //PO Number

  123 // Product Code

  124 // Product Code

How can I "group" the result based on the Purchase Order Number??
Have been dealing with it quite a while, keep searching, but can't really find any resource to achieve so.

I have following code that work but not perfectly

  if(count($products)>0){

            $i=0;

            foreach($products as $v){

                $PDFCONTENT .= '<tr> 

                    <td align="center" width="7%"> </td>

                    <td align="center" width="50%">'.$v['purchase_order_number'].'</td>

                </tr>';

                $i++;

                $PDFCONTENT .= '

                    <tr>

                        <td align="center" width="7%">'.$i.'</td>

                        <td align="center" width="50%">'.$v['ship_product_code].'</td>

                        <td align="center" width="7%">'.number_format($v['qty']).'</td>

                        <td width="7%"> </td>

                    </tr>

                    <tr>

                        <td></td>

                    </tr>

                ';

            }

        }

above code will produce following table

 PO-1 

 122



 PO-2

 123



 PO-2

 124

Please note that I edited the array data here, so I can be more straightforward. There is no problem in outputting the data. Only how can I group the based on the PO Number.

Thank you so much for the help :)

Use following code snippet. With same PO Number we have now only one record.

$fianlProducts = [];
if(count($products)>0){
        foreach($products as $row){
                $fianlProducts[$row['purchase_order_number']]['purchase_order_number'] = $row['purchase_order_number'];
                $fianlProducts[$row['purchase_order_number']]['ship_product_code'][] = $row;
        }
        $i=0;
        foreach($fianlProducts as $v){
                $PDFCONTENT .= '<tr> 
                    <td align="center" width="7%"> </td>
                    <td align="center" width="50%">'.$v['purchase_order_number'].'</td>
                </tr>';
                foreach($v['ship_product_code'] as $w){
                        $i++;
                        $PDFCONTENT .= '
                            <tr>
                                <td align="center" width="7%">'.$i.'</td>
                                <td align="center" width="50%">'.$w['ship_product_code'].'</td>
                                <td align="center" width="7%">'.number_format($w['qty']).'</td>
                                <td width="7%"> </td>
                            </tr>
                            <tr>
                                <td></td>
                            </tr>
                        ';
                }                
        }
}
