array_pop() removes it from the array.
end() changes the internal pointer.
Is the only way really some cludge like:
$my_array[array_pop(array_keys($my_array))];
?

To be fair, what's at the end is arbitrary based on your keys.Jason McCreary– Jason McCreary2011-09-20 19:44:18 +00:00Commented Sep 20, 2011 at 19:44

This works:
list($end) = array_slice($array, -1);
array_slice($array, -1) returns an array with just the last element and list() assigns the first element of slice's result to $end.
@Alin Purcaru suggested this one in comments:
$end = current(array_slice($array, -1));
Since PHP 5.4, this works too:
array_slice($array, -1)[0]

What about
$end = current(array_slice($array, -1)); instead of the list approach for getting the only element of an array?

Cool thanks. I was hoping there was some function or approach I wasn't finding.

Unfortunately list($end) = array_slice($array, -1); doesn't work with associative arrays. So I use function pop_array_nondestructive( $array ) { return end($array); }

because it changes the internal pointer and OP seems to not want to change the internal pointer ? :)

@arnaud I'm aware that it resets the pointer, but at least it puts it at the beginning which is the default. Your solution would be more appropriate for not resetting it at all.
Unfortunately
list($end) = array_slice($array, -1);

function pop_array_nondestructive( $array )
{
return end($array);

- Get last key:
$last_key = array_key_last($my_array); //Get the last key of the given array without affecting the internal array pointer.
- Get last element:
echo $my_array[$last_key];
Comments
end($my_array);
I see nothing bad in changing internal pointer. Nobody is using it these days anyway

Again with a sarcastic answer without reading the question. You should really stop this.
Your Common Sense
you know that's fastest gun problem, lol. still i see no point in the question even after reading it through
Jason McCreary
@Alin, what's the issue here. Although late to the game, it's a valid answer and point that's it's an underused function.
Alin P.
@Both of you. Read the question again. You'll see it eventually.
Jason McCreary
@Alin, I have. Maybe you should as your answer suggests using
end() as well. |
