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

As Mike pointed out (the easiest possible way):

$arr = array( 4 => 'apple', 7 => 'orange', 13 => 'plum' )
echo reset($arr); // Echoes "apple"

If you want to get the key: (execute it after reset)

echo key($arr); // Echoes "4"

From PHP's documentation:

mixed reset ( array &$array );

Description:

reset() rewinds array's internal pointer to the first element and returns the value of the first array element, or FALSE if the array is empty.
