微信公众号最佳实践（ 10.2）回复QQ表情和Emoji表情

回复QQ表情和Emoji表情

微信的的文字发送方有一个笑脸表情等表情符，单击该表情后，我们可以发送这些表情，这些表情包括QQ表情和Emoji表情（也叫符号表情）
如图示：

微信用户和微信公众号都能直接发送或回复相应的QQ表情给对方，微信公众号回复QQ标签的时候，需要回复相应的**表情代码**，这样就能发送相应的表情。这些表情代码被当作文本消息在微信中转义成图标。
QQ表情相应代码如下：

可以使用如下代码来实现文字到QQ表情的转换，这样，在回复的内容中如果有相应的词语，就能转换成相应的QQ表情,代码如下

$face = array('/::)','/::~','/::B','/::|','/:8-)','/::<','/::$','/::X','/::Z','/::\'(','/::-|','/::@','/::P','/::D','/::O','/::(','/::+','/:Cb','/::Q','/::T','/:,@P','/:,@-D','/::d','/:,@o','/::g','/:|-)','/::!','/::L','/::>','/::,@','/:,@f','/::-S','/:?','/:,@x','/:,@@','/::8','/:,@!','/:!!!','/:xx','/:bye','/:wipe','/:dig','/:handclap','/:&-(','/:B-)','/:<@','/:@>','/::-O','/:>-|','/:P-(','/::\'|','/:X-)','/::*','/:@x','/:8*','/:pd','/:<W>','/:beer','/:basketb','/:oo','/:coffee','/:eat','/:pig','/:rose','/:fade','/:showlove','/:heart','/:break','/:cake','/:li','/:bome','/:kn','/:footb','/:ladybug','/:shit','/:moon','/:sun','/:gift','/:hug','/:strong','/:weak','/:share','/:v','/:@)','/:jj','/:@@','/:bad','/:lvu','/:no','/:ok','/:love','/:<L>','/:jump','/:shake','/:<O>','/:circle','/:kotow','/:turn','/:skip','/[]','/:#-0','/[]','/:kiss','/:<&','/:&>');$word = array('微笑','伤心','美女','发呆','墨镜','哭','羞','哑','睡','哭','囧','怒','调皮','笑','惊讶','难过','酷','汗','抓狂','吐','笑','快乐','奇','傲','饿','累','吓','汗','高兴','闲','努力','骂','疑问','秘密','乱','疯','哀','鬼','打击','bye','汗','抠','鼓掌','糟糕','恶搞','什么','什么','累','看','难过','难过','坏','亲','吓','可怜','刀','水果','酒','篮球','乒乓','咖啡','美食','动物','鲜花','枯','唇','爱','分手','生日','电','炸弹','刀','足球','虫','臭','月亮','太阳','礼物','伙伴','赞','差','握手','优','恭','勾','顶','坏','爱','不','好的','爱','吻','跳','怕','尖叫','圈','拜','回头','跳','天使','激动','舞','吻','瑜伽','太极');$message = $keyword; //区别：将 【文字】转换为【QQ表情符号】
$content = str_replace( $word, $face, $message);//区别：将【QQ表情符号】转化为【文字】
$content = str_replace( $face, $word,  $message);

区别：将【文字】转换为【QQ表情符号】

$content = str_replace( $word, $face, $message);

区别：将【QQ表情符号】转化为【文字】
$content = str_replace( $face, $word, $message);

Emoji即表情符号，词义来自日语，是由粟田穰嵩创建的，目前已普遍应用于网络聊天软件中。Emoji表情的一部分如图所示：

Emoji表情包含多个版本，包含 Unified、 DoCoMo、 KDDI、 Softbank、 Google、 Wechat，其中Unified是最官方的版本，也是微信中使用的版本。Emoji表情使用十六进制代码标记，其符号到达700多种，各符号名称、含义及其在各种版本下的十六进制代码可以参考官网，

在微信公众号平台中，公众号回复Emoji表情，不能直接回复代码，需要进行ASCII转码，然后将编码以文本消息回复。

十六进制转码代码如下：

<?phpfunction utf8_bytes($cp){if ($cp > 0x10000){# 4 bytesreturn    chr(0xF0 | (($cp & 0x1C0000) >> 18)).chr(0x80 | (($cp & 0x3F000) >> 12)).chr(0x80 | (($cp & 0xFC0) >> 6)).chr(0x80 | ($cp & 0x3F));}else if ($cp > 0x800){# 3 bytesreturn    chr(0xE0 | (($cp & 0xF000) >> 12)).chr(0x80 | (($cp & 0xFC0) >> 6)).chr(0x80 | ($cp & 0x3F));}else if ($cp > 0x80){# 2 bytesreturn    chr(0xC0 | (($cp & 0x7C0) >> 6)).chr(0x80 | ($cp & 0x3F));}else{# 1 bytereturn chr($cp);}}
?>

构造文本消息时，将相应的十六进制作为参数填入转码函数中即可，特别要注意的是，部分表情有两组十六进制代码，比如”中国国旗”，“美国国旗”，，需要将两组十六进制都进行转码后拼接，代码实现如下

  private function receiveText($object){$keyword = trim($object->Content);$content = "中国国旗：".utf8_bytes(0x1F1E8).utf8_bytes(0x1F1F3)."\n"."美国国旗：".utf8_bytes(0x1F1FA).utf8_bytes(0x1F1F8)."\n"."男女牵手：".utf8_bytes(0x1F46B)."\n"."仙人掌：".utf8_bytes(0x1F335)."\n"."电话机：".utf8_bytes(0x260E)."\n"."药丸：".utf8_bytes(0x1F48A);$result = $this->transmitText($object, $content);return $result;}

index.php整体代码如下：
