Question:
I'm using the PDO class but I'm triying to remove all chars except...:
function cleaner($str){ return preg_replace('/[^a-zA-Z0-9éà êïòé\,\.\']/',' ',trim($str)); }
As you can see, it's a simple function, but it removes all chars éà êïòé
example: cleaner('$#$<<>-//La souris a été mangée par le chat ') //returns
La souris a t mang e par le chat (The mouse has been eaten by the cat :) )
Any help will be appreciate
Solution:1
$str = '$#$<<>-//La souris a été mangée par le chat '; $str = preg_replace('/[^a-zA-Z0-9éà êïòé\,\.\']/u',' ',trim($str)); $str = '$#$<<>-//La souris a été mangée par le chat '; $str = preg_replace('/[^\p{L}\,\.\']/u',' ',trim($str));
Both the snippets worked for me, on PHP 5.3. The second regular expression is less restricted, and accepts all Unicode letters.
Solution:2
You need to add /u pattern modifier to your pattern to turn on UTF-8 support in PCRE. This is assuming everything is in UTF-8 already.
