php处理APP中 emoji表情包的方法

解决方案；将表情转换成base64可以见格式，由于转换后长度过大，将其替换成对应字符保存入数据库

<?php 
class Emoji
{
    /**
     * 将表情转成对应代表字符串
     * @param string $content
     */
    public static function emojiEncode($content = '')
    {
        if (!$content) {
            return $content;
        }
        $content = json_encode($content);

        $emoji = requrie_once('emoji.php');
        $content = str_replace(array_keys($emoji['regenEncode']), $emoji['regenEncode'], $content);
        $content = json_decode($content, true);
        return $content;
    }

    /**
     * 将对应字符串转成表情
     * @param string $content
     */
    public static function emojiDecode($content = '')
    {
        if (!$content) {
            return $content;
        }
        $content = json_encode($content);

        $emoji = requrie_once('emoji.php');
        $content = str_replace(array_keys($emoji['regenDecode']), $emoji['regenDecode'], $content);
        $content = json_decode($content, true);
        return $content;
    }
}
