Encoder correctement

Je me suis souvent arraché les cheveux sur un problème de caractères spéciaux qui ressortent sous la forme de signe ésotérique comme Ã@ ou autre.

Pour en finir une bonne fois pour toute, il y a la fonction htmlentities qui s'utilise ainsi :

htmlentities($chaine , ENT_COMPAT, "UTF-8" )

voici les différentes options :

htmlentities(string, quotestyle, character-set)

quotestyle	Optional. Specifies how to encode single and double quotes. The available quote styles are: ENT_COMPAT - Default. Encodes only double quotes ENT_QUOTES - Encodes double and single quotes ENT_NOQUOTES - Does not encode any quotes
