How to determine the first and last iteration in a foreach loop?

What is the best way to establish that the foreach loop is in it in the final loop and performs various functions accordingly?

Answer 1

The way I would like to approach this is to increase the increment of the variable and check this variable for the size of the array ( count()):

$i = 0;
$c = count($array);

foreach($array as $key => $value) {
    $i++;
    if ($i == $c) {
        // last iteration
    }
    else {
        // do stuff
    }
}

This may, obviously, not be the most effective method.

Answer 2

There are two ways to do this:

• , , .
• for foreach if(count($someArr) - 1 == $currentIteration). , .

Answer 3

IMHO the best way is to use a loop forfor such cases.

Answer 4

um ... use this:

 $i =0;
 $c = count($employeeAges);
    foreach( $employeeAges as $key => $value){
    if($c-$i<=1){
          //DO SOMETHING
        }else{
          //default for other loops
        }
        i++;
     }
