数组不总和高于7的数字

Question

Problem: This is all about ranking. This rank should contain numbers from zero up to ten. However, I notice that the sum of my array that stores the values are not entering numbers higher than 07. So, it can only sums the number from 00 up to 07! I couldn't find the mistake.

Code:

<tbody>
<?php
  $scores = array(
  "Kyle"   => array("-", 04, 04, 06, 04, 05, 04, 04),
  "Bill"   => array("-", 04, 09, 04, 07, 08, 04, 10),
  "Adam"   => array("-", 04, 04, 04, 01, 04, 04, 04),
  "Johnny" => array("-", 08, 04, 10, 04, 08, 08, 04),
?>

###function to return the sum
function cmp($a, $b) {
  return array_sum($b) - array_sum($a);
}

####sort the ranking into the td
uasort($scores, "cmp");
foreach($scores as $key=>$value) {
  echo "<tr>";
  echo "<th>$key</th>";
  echo "<td class='total' align='center' valign='middle'>" . array_sum($value) . "</td>";
  for($x=0; $x<count($value); $x++) {
    echo "<td class='games tip' align='center' valign='middle'>".sprintf('%02d', $value[$x])."</td>";
  }
  echo "</tr>";
}
?>
</tbody>

Thank you!

Numbers beginning with 0 are treated as octal numbers, and may only contain digits from 0 to 7. Any other digit is treated as a delimiter, not part of the number. So 08 and 09 are interpreted as 0.

Get rid of all you leading digits:

  $scores = array(
  "Kyle"   => array("-", 4, 4, 6, 4, 5, 4, 4),
  "Bill"   => array("-", 4, 9, 4, 7, 8, 4, 10),
  "Adam"   => array("-", 4, 4, 4, 1, 4, 4, 4),
  "Johnny" => array("-", 8, 4, 10, 4, 8, 8, 4),
  );
