這篇文章主要介紹了PHP使用微信開發模式實現搜尋已發送圖文及匹配關鍵字回复的方法,涉及php針對微信json格式數據的解析與正則匹配相關操作技巧,需要的朋友可以參考下
本文實例講述了PHP使用微信開發模式實現搜尋已發送圖文及匹配關鍵字回應的方法。分享給大家供大家參考,具體如下:
用戶發送關鍵字,搜尋對應的圖文回覆。
模擬登陸就不說了
右鍵看「已傳送」圖片頁的原始碼,圖文部分是json格式的。
複製程式碼 程式碼如下:

資料庫:
使用者回覆關鍵字,然後查詢回覆對應圖文資訊。
select app_id from table where title like '%162期%' limit 1; select * from table where app_id=XXXXX;2》根據關鍵字:
select * from table where title like '%故事%' limit 10;
