Description
mixed mb_internal_encoding ([ string $encoding = mb_internal_encoding() ] )
//Set/Get the internal character encoding
Parameters
encoding
encoding is the character encoding name used for the HTTP input character encoding conversion, HTTP output character encoding conversion, and the default character encoding for string functions defined by the mbstring module. You should notice that the internal encoding is totally different from the one for multibyte regex.
字符編碼用于HTTP輸入，輸出字符編碼轉(zhuǎn)換，默認(rèn)的字符編碼由mbstring模塊字符串函數(shù)定義的。你應(yīng)該注意到內(nèi)部編碼完全不同于多字節(jié)的正則表達(dá)式。
Return Values
If encoding is set, then Returns TRUE on success or FALSE on failure. In this case, the character encoding for multibyte regex is NOT changed. If encoding is omitted, then the current character encoding name is returned.
如果設(shè)置了編碼，則成功返回TRUE或失敗時(shí)返回FALSE。在這種情況下，對(duì)多字節(jié)字符編碼不改變正則表達(dá)式。如果省略編碼，則返回當(dāng)前字符編碼名稱(chēng)。
