How to use UTF-8 characters in a PHP-script?

How to use UTF-8 characters in a PHP-script?

I know there is an escape character to interpret the next two characters as UTF-8. That escape is \s. So \xFF works, which will represent 'ÿ'. But now I want to remove zero-width spaces (U+200B) from a string. How to do that? Can I开发者_Python百科 use the function str_replace(), or maybe preg_replace()?

Thanks in advance.

This worked for me:

$str = str_replace("\xe2\x80\x8b", '', $str);

You may want to try mb_ereg_replace() or iconv() with str_replace.

Remove zero-width space:

$str = str_replace(chr(13), "", $str);
