PHP: Determine Number of Elements in an Array / Length of Array

Today, I would like to show you how to get the number of elements that are stored in an array in PHP - or, in other words, how to determine the length of an array.

For this, let us look at a small example:

$arr = array(1, 2, 3);
echo count($arr);  // 3

First, we are creating a new array with three elements (1/2/3). You can just use the function array() for creating a new array and parsing the desired elements. We are saving the new array in the variable $arr.

After that, we already want to specify the length of the array. For this, we can use the function count() to which we simply can pass the array variable. As expected, the result is 3.
