I am using the php function bin2hex on some strings, and one of them have a division sign character ÷ (Dec: 247, Hex: f7).
But when I try:
echo bin2hex('÷');
I get:
c3b7
The first problem is that the c3 character was added and I have no idea where it comes from (c2 also gets added before other characters).
And the second and main problem, php is giving me the hex string “b7” as a representation of the division sign ÷, but b7 represents · and not ÷.
Anyone knows whats going on here?
It seems that your source code is Unicode-encoded so that your editor encodes ‘÷’ in unicode (eg. UTF-8). “c3b7” is two-byte encoded form of ‘÷’ (See here). Make sure your source code is ASCII-encoded to get the effect you desire.
