This article illustrates the usage of the character encoding conversion function in PHP, and shares it for everyone's reference. The implementation methods are as follows: Generally speaking, in the Web page program, especially involves the reading of the database process, often the most annoying is the problem of character encoding, php4.0.6 above version provides mb_convert_encoding can facilitate the conversion of the code. Specifically as follows: Copy Code code as follows:
