I would like to change all special characters in my string but I want to keep all accented ones. Is it possible with a preg_replace() ?

My current code:

preg_replace('/[^A-Za-z0-9\-]/', '', $string);

Try Unicode:

preg_replace('/[^\p{L}0-9\-]/u', '', $string);

\p{L} is a Unicode property that matches all letters in any language, Unicode properties on php.net

  • The documentation for PHP seems more accurate for this question: http://www.php.net/manual/en/regexp.reference.unicode.php – Ignacio Lago Jan 16 '14 at 11:51
  • @IgnacioLago, thanks for that link, added it to the answer – stema Jan 16 '14 at 12:05
  • @Dimi, just add additional characters to your negated character class, e.g. `[/[^\p{L}0-9&\-]/]` – stema Jan 16 '14 at 12:06
