How do I set the foreach loop to start at the last array?

Question

How do I set my foreach loop to start looking at the last entry of the array then each loop will go backwards instead of forward?

Thank you.

Answer 1

You could just reverse the array:

$reverse = array_reverse($array, true); // true to preserve keys
foreach($reverse as $key => $value) { /* etc. */ }

Or if you're sure that the array contains only numeric keys, this is probably faster:

for($i = count($array) - 1; $i >= 0; $i--) {
  /* etc. */
}

Answer 2

foreach(array_reverse($array, true) as $key=>$value)

The array_reverse function will reverse an array.

Answer 3

You could do this:

$values = array();
$max = count($values);

foreach($i = $max; $i > 0; $i--) {
    $key = $values[$i];
    // do something with the key
}
