Convert php Chinese characters to binary decimal hexadecimal numerals

Php Chinese characters are converted into binary-decimal hexadecimal numbers & lt ;? Php *** converts a Chinese character to a unicode universal function, independent of any library, and other user-defined functions, but conditional: the input parameters of this file and the function should be UTF-8 encoded. otherwise, function conversion is required. * In fact, reverse conversion functions can also be easily compiled, not limited to Chinese characters, strange why PHP does not have a ready-made function * @ authorxieye php converts Chinese characters to binary-decimal hexadecimal numbers
