The phpiconv function solves the problem of UTF-8 and gb2312 encoding conversion.

$ Content = iconv ("UTF-8", "gb2312", $ content ); This is actually the opposite. it seems that UTF-8 is indeed converted to gb2312, but the actual operation is often ended in failure. why? The reason is simple, because all functions are execution errors, and unfortunately iconv (); finally, an error occurs. Correct practice: $ Content = iconv ("UTF-8", "gb2312 // ignore", $ content ); You only need to add a // ignore to the end. with this added, the iconv () function can ignore the error and continue execution. Similarly, to replace gb2312 with UTF-8, you only need to write $ content = iconv ("gb2312", "UTF-8 // ignore", $ content );.
