Reverse order of foreach list items

Question

I would like to reverse the order of this code\'s list items. Basically it\'s a set of years going from oldest to recent and I am trying to reverse that output.

Answer 1

Walking Backwards

If you're looking for a purely PHP solution, you can also simply count backwards through the list, access it front-to-back:

$accounts = Array(
  '@jonathansampson',
  '@f12devtools',
  '@ieanswers'
);

$index = count($accounts);

while($index) {
  echo sprintf("<li>%s</li>", $accounts[--$index]);
}

The above sets $index to the total number of elements, and then begins accessing them back-to-front, reducing the index value for the next iteration.

Reversing the Array

You could also leverage the array_reverse function to invert the values of your array, allowing you to access them in reverse order:

$accounts = Array(
  '@jonathansampson',
  '@f12devtools',
  '@ieanswers'
);

foreach ( array_reverse($accounts) as $account ) {
  echo sprintf("<li>%s</li>", $account);
}

Answer 2

If your array is populated through an SQL Query consider reversing the result in MySQL, ie :

SELECT * FROM model_input order by creation_date desc
