Sets the automatic character
encoding detection order to encoding.
Parameter-Liste
-
encoding -
encodingis an array or comma separated list of character encoding. See supported encodings.If
encodingis omitted ornull, it returns the current character encoding detection order as array.This setting affects mb_detect_encoding() and mb_send_mail().
mbstringcurrently implements the following encoding detection filters. If there is an invalid byte sequence for the following encodings, encoding detection will fail.UTF-8,UTF-7,ASCII,EUC-JP,SJIS,eucJP-win,SJIS-win,JIS,ISO-2022-JPFor
ISO-8859-*,mbstringalways detects asISO-8859-*.For
UTF-16,UTF-32,UCS2andUCS4, encoding detection will fail always.
Rückgabewerte
When setting the encoding detection order, true is returned on success or false on failure.
When getting the encoding detection order, an ordered array of the encodings is returned.

Beispiel #2 Example showing useless detect orders
; Always detect as ISO-8859-1 detect_order = ISO-8859-1, UTF-8 ; Always detect as UTF-8, since ASCII/UTF-7 values are ; valid for UTF-8 detect_order = UTF-8, ASCII, UTF-7
