PHP Array Length: Get Count with Examples

In PHP, you can use the count() function to get the length of an array (i.e. the number of elements). Here is a simple example demonstrating how to use the count() function to get the length of an array:

<?php
// 创建一个数组
$array = array('apple', 'banana', 'orange', 'grape');

// 获取数组的长度
$length = count($array);

echo "数组的长度为：".$length;
?>

In this example, the count($array) function will return the length of the array $array, which is 4. You can integrate the above code into your PHP script to obtain the length of the array based on your specific circumstances.
