Configurare PHP pentru UTF-8

php.conf

default_charset			= UTF-8		; Default character set for auto content type header

[mbstring]
mbstring.language		= Neutral	; Set default language to Neutral(UTF-8) (default)
mbstring.internal_encoding	= UTF-8		; Set default internal encoding to UTF-8
mbstring.encoding_translation	= On		;  HTTP input encoding translation is enabled
mbstring.http_input		= auto		; Set HTTP input character set dectection to auto
mbstring.http_output		= UTF-8		; Set HTTP output encoding to UTF-8
mbstring.detect_order		= auto		; Set default character encoding detection order to auto
mbstring.substitute_character	= none		; Do not print invalid characters

mbstring.func_overload = On ; CU RISCURI CICA?

; Deal with non-multibyte-safe functions in PHP
mbstring.func_overload	= 7 ; All non-multibyte-safe functions are overloaded with the mbstring alternatives
; (ASTA DOAR OPTIONAL daca nu faceti pasul urmator)

[exif]
exif.encode_unicode = UTF-8

Înlocuiţi toate apelurile la funcţiile de mai jos, cu variantele lor multibyte, sau optaţi pentru mbstring.func_overload, care cică prezintă nişte riscuri (vezi mbstring)
