Definition and Usage
定义和用法

The array_walk_recursive() function runs each array element in a user-made function. The array's keys and values are parameters in the function. The difference between this function and the array_walk() function is that with this function you can work with deeper arrays (an array inside an array). Returns True or False
array_walk()函数将一个数组中的元素应用于用户自定义函数中；该数组中的键和值作为用户自定义函数中的参数。该函数与array_walk()函数的不同点在于：使用array_walk_recursive()函数，你可以使用嵌套的数组[deeper arrays]（即：数组中的数组）。

Syntax
