php - in foreach, isLastItem() exists?

Question

Using a regular for loop, it's possible to comapred the current index with the last to tell if I'm in the last iteration of the loop. Is there a similar thing when using foreach? I mean something like this.

foreach($array as $item){
  //do stuff
  //then check if we're in the last iteration of the loop
  $last_iteration = islast(); //boolean true/false
}

If not, is there at least a way to know the current index of the current iteration like $iteration = 5, so I can manually compare it to the length of the $array?

Answer 1

The counter method is probably the easiest.

$i = count($array);
foreach($array as $item){
  //do stuff
  //then check if we're in the last iteration of the loop
  $last_iteration = !(--$i); //boolean true/false
}
