The count Function

The count function counts the number of array elements.

Syntax

count(Countable|array $value, int $mode = COUNT_NORMAL): int

Let's count the number of array elements:

<?php
	$arr = ['a', 'b', 'c', 'd', 'e'];
	echo count($arr);
?>

Code execution result:

Get the last element of the array using the count function:

<?php
	$arr = ['a', 'b', 'c', 'd', 'e'];
	echo $arr[count($arr) - 1];
?>

Code execution result:
