Count PHP Array Elements: Simple Guide

To output the number of elements in a PHP array, you can use the count() function. Here is a simple example code to output the number of elements in an array:

<?php
// 创建一个包含一些元素的数组
$myArray = array("apple", "banana", "orange", "grape");

// 使用 count() 函数获取数组元素的个数并输出
$count = count($myArray);
echo "数组元素的个数是：" . $count;
?>

In the above example, we start by creating an array $myArray with a few elements. Next, we use the count() function to get the number of elements in the array and store the result in the variable $count. Finally, we print the number of array elements using an echo statement.

You can save the above code in a .php file, then access the file to view the number of array elements.
