回声多个阵列？

Question

I have a form that gives me multiple arrays when submit. My question is if there is a smart way to echo out (to show the user) all the arrays instead of doing a foreach for each array?

Could a solution be to do a function with a foreach loop?

HTML from the TASKS input:

<td><input type="checkbox" name="tasks[<?php echo($value[0]);?>]"value=<?php echo($key[0]);?>></td>

My PHP script:

if(isset($_POST['submit'])) {
     $tasks = $_POST['tasks'];
     $user = $_POST['user'];
     $pickup_at = $_POST['pickup_at'];
     $message = $_POST['message'];
     $price = $_POST['price'];
     $part_missing = $_POST['part_missing'];

Foreach ex. on the TASKS array

foreach($tasks as $key => $keys)
{
   echo $key ."<br>";
}

All the arrays should have indexes in parallel. You only need to use the indexes from one of them, and can then use that as indexes into all the rest:

foreach ($tasks as $i => $task) {
    echo "Task $i: $task<br>";
    echo "  User: {$user[$i]}<br>";
    echo "  Pickup at: {$pickup_at[$i]}<br>";
    ...
}
