';');} principle analysis: var_export sets the second parameter to true. Back to the array prototype string, convert the string to UTF-8 encoding, and then use eval to execute and return (similar to anonymous functions ?), This is a perfect solution. Later: most of the methods found on the Internet use recursive calling of iconv. if there are too many array elements or a large number of dimensions, the performance will be poor. the better is the native code method, no need to consider whether it is an n-dimensional array or an associated array. everything has been completed automatically to ensure data consistency before and after array conversion.
