PHP: how to move an array pointer inside a foreach loop?

$animals = array('cat', 'dog', 'horse', 'elephant');
foreach($animals as $animal)
{
   var_dump($animal);
   next($animals);
}

The above code: cat, dog, horse, elephant. I thought that the function nextshould move the internal pointer $animalsand so I should get this output instead of: cat, horse.

How to make $ animals internal pointer move forward (and back) so that it is affected in foreach?

EDIT 1:

From the manual:

Since foreach relies on a pointer to an internal array, changing it within a loop can lead to unexpected behavior.

However, I think this is what I need to do.

EDIT 2:

In the section "Your common sense" I will provide a more detailed explanation of my problem. Here is some psuedo code:

array $foos;

start loop of $foos
 - do thing #1
 - do thing #2
 - do thing #3
 - keep doing thing #3 while the current value of $foos in the loop meets a certain criteria
loop

  print "$index:";
  var_dump($animal);
  next($animals);

$animals = array('cat', 'dog', 'horse', 'elephant');
foreach($animals as $animal)

You do not need to increment the pointer manually at the end of the foreach loop - this is done automatically. You do not need anything else:

foreach($animals as $animal) {
    var_dump($animal)
}
