Foreach循环遍历多维数组

Question

I have this set of data that I get from html form. It is basically a multidimensional array.

Data

array(3) {
  ["r1"]=>
  array(2) {
    [0]=>
    string(1) "2"
    [1]=>
    string(1) "4"
  }
  ["r2"]=>
  array(2) {
    [0]=>
    string(1) "5"
    [1]=>
    string(2) "96"
  }
  ["tekma_id"]=>
  array(2) {
    [0]=>
    string(1) "7"
    [1]=>
    string(1) "8"
  }
}

Problem: What i want to do, is to go over this array and for each iteration create a data variable(array).

So for example:

First iteration:

$data = array(
   'r1' => '2'
   'r2' => '5'
   'tekma_id' => '7'
)

Second iteration:

$data = array(
   'r1' => '4'
   'r2' => '96'
   'tekma_id' => '8'
)

I've tried with this:

foreach ($data as $key => $value) {
    foreach ($value as $index => $v) {
        echo "<br>";
        echo "r1: $v";
        echo "<br>";
        echo "r2: $v";
        echo "<br>";
        echo "tekma_id: $v";
    }
}

But it didn't work. Sorry for my bad english and thanks for any help. Cheers!

How about this?

$array = array(
    'r1' => array(2, 4),
    'r2' => array(5, 96),
    'tekma_id' => array(7, 8));

$keys = array_keys($data);
$iterations = count($array[$keys[0]]);

for($i = 0; $i < $iterations; $i++) {
    $data = array();
    foreach($array as $key => $value) {
        $data[$key] = $value[$i];
    }
    print_r($data);
}

Output:

Array
(
    [r1] => 2
    [r2] => 5
    [tekma_id] => 7
)
Array
(
    [r1] => 4
    [r2] => 96
    [tekma_id] => 8
)
