如何在PHP中将ASCII编码的字符串转换为UTF8？ [重复]

Question

This question already has an answer here:

• Convert ASCII TO UTF-8 Encoding 6 answers

I tried to do: file_put_contents ( $file_name, utf8_encode($data) ) ; But when i check the file encoding from the shell with the linux command: 'file file_name' I get: 'file_name: ASCII text'

Does it mean that the utf8_encoding didn't worked? if so, what is the right way to convert from ASCII to UTF8

Answer 1

If your string doesn't contain any non-ASCII characters, then you likely won't see differences, since UTF-8 is backwards compatible with ASCII. Try writing, for example, the text "1000 さくら" and see what happens.
