php智能识别收货地址信息

数据库 2018-11-05 18:11:05 阅读次数: 0

功能需求：用户输入混合的收货地址，能智能识别出地址，手机，姓名

准备:需要两张表，一张地区表和一张姓氏表 (地区表得到应该不难，姓氏表我是搜索中国姓氏自制的哈，底部会附上表结构)

  • 思路：主要思路分两种，一种是用户正常输入全地址，则顺序按地区等级匹配地址；另一种用户非正常输入（省市区有缺少的），则全面模糊搜索表，再根据结果对比原地址。

  • 提醒：手机可以根据自己需求修改正则；
    名字只匹配中文，可以根据自己的需求修改姓氏表以及正则
    地址匹配暂无发现问题

效果图：在这里插入图片描述
代码：

        $result_sub = $this->addressVague($address);
        // 只有全匹配对才替换，否则不做任何改变
        if($result_sub['level'] == 3){
            $result = $result_sub;
