Detect encoding and make everything UTF-8

Question

I\'m reading out lots of texts from various RSS feeds and inserting them into my database.

Of course, there are several different character encodings used in the fee

Answer 1

The interesting thing about mb_detect_encoding and mb_convert_encoding is that the order of the encodings you suggest does matter:

// $input is actually UTF-8

mb_detect_encoding($input, "UTF-8", "ISO-8859-9, UTF-8");
// ISO-8859-9 (WRONG!)

mb_detect_encoding($input, "UTF-8", "UTF-8, ISO-8859-9");
// UTF-8 (OK)

So you might want to use a specific order when specifying expected encodings. Still, keep in mind that this is not foolproof.
