The above PHP code can also solve the problem of converting strings into arrays. Let’s introduce the description of the parse_str() function so that you can have a good impression in your mind.

parse_str() 函数把查询字符串解析到变量中。
parse_str(string,array)
string:需要转换的字符串；
array:返回到一个数组中；
如果没有设置array的话就覆盖同名变量
