Detailed introduction to array encoding

function array_iconv($in_charset,$out_charset,$arr){ return eval('return '.iconv($in_charset,$out_charset,var_export($arr,true).';')); }Copy code principle analysis : var_export sets the second parameter to true, returns the array prototype string, converts the string to utf-8 encoding, and then uses eval to perform the return (similar to an anonymous function?), which perfectly solves the problem. Subsequent: The method found online is mostly the method of calling iconv recursively. If the array elements are too large or the number of dimensions is more, the performance is definitely not good. The array is still associated with an array, and everything has been automatically completed, ensuring that the data before and after the array conversion is consistent. In terms of the length of the code and the comparison of the cycle and native methods, the method of this article is good.
