Get the first element of an array

Question

I have an array:

array( 4 => \'apple\', 7 => \'orange\', 13 => \'plum\' )

I would like to get the first element of this array. Expect

Answer 1

Keep this simple! There are lots of correct answers here, but to minimize all the confusion, these two work and reduce a lot of overhead:

key($array) gets the first key of an array
current($array) gets the first value of an array

EDIT:
Regarding the comments below. The following example will output: string(13) "PHP code test"

$array = array
(
   '1'           => 'PHP code test',  
   'foo'         => 'bar', 5 , 5 => 89009, 
   'case'        => 'Random Stuff: '.rand(100,999),
   'PHP Version' => phpversion(),
   0             => 'ending text here'
);

var_dump(current($array));
