How to find the array length in PHP

Question

I want to find the number of elements in an array i.e. the length of the array. What function should I use?

Answer 1

You can use the PHP function count(). It returns the number of elements in an array.

Here is an example:

<?php
$arr=array("apple", "banana", "cat", "dog");
echo count($arr);
?>

The above code will return 4.
