如何在PHP中计算未知数组的值

Question

I have this form but would like to get the total. Please how can I calculate this array?

...While(ticket table row)
{
  <input type="text" name="ticket[][price]" id="ticket[][price]" value="12">
  <input type="text" name="ticket[][fee]" id="ticket[][fee]" value="3462">
  <select name="ticket[][qty]">
     <option value="1">1
     <option value="2">2
     <option value="3">3
     <option value="4">4
     <option value="5">5
     <option value="6">6
  </select>
}

Eg. $total = ticket[][price] + ticket[][fee] * ticket[][qty];

Answer 1

Maybe something like this?

$total = 0;
foreach ($_POST['ticket'] as $ticket) {
  $total += $ticket['price'] + $ticket['fee'] * $ticket['qty'];
}

print $total;
