Utf8 is used for saving,
Question 1: Haha is UTF-8 encoded ?? Why can a function be converted from ascii to hexadecimal. The result is \ xe5 \ x93 \ x88 \ xe5 \ x93 \ x88.
I have checked that the hexadecimal format of Haha's ascii code is 54c8 54c8, which is obviously different.
Cannot understand
------ Solution --------------------
It is not appropriate to use "ascii" here, but "convert to hexadecimal,
The function is actually used to represent the string encoding in hexadecimal format.
So all your questions are justified.
It is also funny to write "not-for-profit organizations or individuals can reprint them with confidence, and ask the author's consent for commercial purposes" on the function head,
Because such a simple code is not original, you can write the same code without looking at it,
Therefore, you certainly do not need to "obtain the author's consent"

Return '\ X'. substr (chunk_split (bin2hex ($ str), 2,' \ X'), 0,-2 );
}
// Convert the hexadecimal format to ......
