Last position of an Array

You can use the end () .

$ultimo = end($minhaArray);

Another alternative is array_pop() but this method also removes the last element, I do not know if that's what you need.

If it is an associative array, you need to put the array in the last item and then fetch key()

end($minhaArray);         
$ultimaChave= key($minhaArray);

If you want to create a new array with the last element, you can use the array_slice ( ) , this method allows you to create a new array with several elements of the original array, through the second parameter that indicates how many end elements should be passed.

$ultimo = array_slice($minhaArray, -1)

To leave the array in the last element, use the end ()

$arr = array ('maça', 'banana', 'melancia', 'morango', 'uva');
echo end($arr);

output is: uva

The end () function makes the pointer point to the last element of the array, soon if you do:

$array = array('primeiro','segundo','último');

var_dump(current($array));
var_dump(end($array));
var_dump(current($array));

The output will be:

string 'primeiro' (length=8)
string 'último' (length=6)
string 'último' (length=6)

The function current () , returns the current position of the array
