How to determine the first and last iteration in a foreach loop?
If you prefer a solution that does not require the initialization of the counter outside the loop, then you can compare the current iteration key against the function that tells you the last / first key of the array.
PHP 7.3 and newer:
foreach ($array as $key => $element) { if ($key === array_key_first($array)) { echo 'FIRST ELEMENT!'; } if ($key === array_key_last($array)) { echo 'LAST ELEMENT!'; }}PHP 7.2 and older:
foreach ($array as $key => $element) { reset($array); if ($key === key($array)) { echo 'FIRST ELEMENT!'; } end($array); if ($key === key($array)) { echo 'LAST ELEMENT!'; }}
