Question: How to get the first element of an array using PHP?

If you have the array

$array = array('a','b','c','d');

Answer:

Use the array_shift function available in PHP 4 and 5 which shifts an element off the beginning of an array. See example below

$array = array('a','b','c','d');
$first_element = array_shift($array);
echo $first_element;
