I have a Multidimensional array that I am trying feverishly to properly sort by the date.
So far I've got:
usort($respArr, function($a, $b){
$t1 = strtotime($a['PublishDate']);
$t2 = strtotime($b['PublishDate']);
return $t1 - $t2;
});
array_reverse($respArr);
echo '<pre>';
print_r($respArr);
echo '</pre>';
echo '<hr />';
Here's some of the output from the above:

However, the array is not reversed, as you can tell above. Can anyone help me with this?
It's showing me that the array is indeed sorted by the 'PublishDate', however, in the reverse order that I need it in.

The array_multisort() function returns a sorted array. You can assign one or more arrays. The function sorts the first array, and the other arrays follow, then, if two or more values are the same, it sorts the next array, and so on.
Sorting a multidimensional array by element containing date. Use the usort() function to sort the array. The usort() function is PHP builtin function that sorts a given array using user-defined comparison function. This function assigns new integral keys starting from zero to array elements.
The arsort() function sorts an associative array in descending order, according to the value. Tip: Use the asort() function to sort an associative array in ascending order, according to the value. Tip: Use the krsort() function to sort an associative array in descending order, according to the key.
To PHP sort array by key, you should use ksort() (for ascending order) or krsort() (for descending order). To PHP sort array by value, you will need functions asort() and arsort() (for ascending and descending orders).
The actual problem is you're not assigning the result of array_reverse to anything
// change this
array_reverse($respArr);
// to this
$respArr = array_reverse($respArr);
