How do you get the first and last element of an array in PHP?

If you want to get the first element of an array in PHP, you can use the reset function. This function sets the internal pointer of the array to the first element, and returns the value of the first element.

For example:

$array = array('a', 'b', 'c');
$first = reset($array);
echo $first; // Outputs "a"

To get the last element of an array in PHP, you can use the end function. This function sets the internal pointer of the array to the last element, and returns the value of the last element.

For example:

$array = array('a', 'b', 'c');
$last = end($array);
echo $last; // Outputs "c"

You can also use the reset and end functions in combination with the prev and next functions to move the internal pointer of the array to the desired element.

For example:

$array = array('a', 'b', 'c');
reset($array); // Set pointer to first element
$second = next($array); // Get second element
end($array); // Set pointer to last element
$second_to_last = prev($array); // Get second to last element
echo $second; // Outputs "b"
echo $second_to_last; // Outputs "b"

You can also use array indices to access specific elements in an array. For example:

$array = array('a', 'b', 'c');
$first = $array[0];
$last = $array[2];
echo $first; // Outputs "a"
echo $last; // Outputs "c"
