Bug description:Implement array_first() and array_last()
Description:
------------
Retrieving the first or the last element of an array (without modifying the
array) is a very common task.
It is really annoying that PHP wouldn't come with built-in functions to do
that.
Can you please implement the following 2 array functions:
array_first(array $array) - returns the first element of $array
array_last(array $array) - returns the last element of $array
Also consider implementing another pair of function to retrieve the keys:
array_first_key and array_last_key.
Test script:
---------------
$test = array(
100 => "a",
200 => "b",
300 => "c",
400 => "d");
echo array_first($test)."\n";
echo array_last($test)."\n";
echo key($test)."\n";
echo implode(",", $test);
Expected result:
----------------
a
d
100
a,b,c,d
Actual result:
--------------
Fatal error: Call to undefined function array_first() on line 3
