$length = count($array); echo “数组的长度为:” . $length; “` 在上述代码中,我们首先创建了一个包含5个元素的数组,然后使用count()函数计算了这个数组的长度并将结果保存在$length变量中,最后将结果输出。 运行上述代码,我们会得到以下输出: “` 数组的长度为:5 “` 正如我们所期望的那样,输出结果是5...
$multidimensionalArray = [ [1, 2, 3], [4, 5, 6], [7, 8, 9] ]; // 计算多维数组的长度 $length = getArrayLength($multidimensionalArray); echo “多维数组的长度为: $length”; “` 在上面的示例代码中,我们定义了一个名为 `getArrayLength` 的函数,该函数使用递归的方式来遍历多维数组,并...

3) Multidimensional arrays: Multidimensional arrays are arrays within arrays, allowing you to create more complex data structures. With multidimensional arrays, you can store and access data in a hierarchical manner. Each element of a multidimensional array can be an array itself, enabling the creatio...
Multidimensional Arrays Amultidimensional arrayis an array in which each element may also be an array, and each element in the sub-array can also be an array or have another array within it, and so on. Below is an example of a multidimensional array. ...
