PHP微信開發教程之搜尋已發送圖文及匹配關鍵字回複的方法

這篇文章主要介紹了PHP使用開發模式實現搜尋已發送圖文及匹配關鍵字回複的方法,涉及php針對json格式資料的解析與正則匹配相關操作技巧,需要的朋友可以參考下

本文執行個體講述了PHP使用開發模式實現搜尋已發送圖文及匹配關鍵字回複的方法。分享給大家供大家參考，具體如下：

使用者發送關鍵字，搜尋相應的圖文進行回複。

類比登陸就不說了

右鍵看“已發送”圖片頁的原始碼，圖文部分是json格式的。

複製代碼 代碼如下:

直接解析json即可。

<?php$wechatObj = new wechatappmsg();$wechatObj->getappmsg('這裡是json');class wechatappmsg{  function getappmsg($content){    //require_once 'db.php';    $jsonstr=$content;    //   $jsonstr='{"msg_item":[{"id":79544,"type":9},{}]}';    $jsonstr = iconv('gbk', 'utf-8', $jsonstr);    $result = json_decode($jsonstr);    $name=$result->msg_item;    // var_dump($name);    //   echo '<br/>json:'.$result;    $size=count($name);    echo '<br/>size:'.$size;    //  exit;    for($i=0;$i<$size;$i++){      $multi_item=$name[$i]->multi_item;      $size2=count($multi_item);      $app_id=$name[$i]->app_id;      $create_time=$name[$i]->date_time;//發送時間      //  echo '<br/>app_id:'.$app_id;      $create_time=date ("Y-m-d H:i:s", $create_time);//時間轉換      echo '<br/>create_time:'.$create_time;      for($j=0;$j<$size2;$j++){        $title=$multi_item[$j]->title;//標題        $pic_url=$multi_item[$j]->cover;//圖片地址        $digest=$multi_item[$j]->digest;//簡要        $content_url=$multi_item[$j]->content_url;//圖文地址        $t = iconv('utf-8', 'gbk', $title);        echo '<br/>title:'.$t;        echo '<br/>Link:'.$content_url;        preg_match("/mid=([0-9]+)&/",$content_url,$string);        $app_mid=$string[1];//一次發送的多個圖文，這個ID值可以判斷這兩個圖文是同一次發送的        echo '<br/>app_mid:'.$app_mid;        //這裡可以直接進行入庫//$x=saveappmsg($pic_url,$title,$digest,$content_url,$create_time,$app_mid); sleep(3);      }      echo '<br/>-------------------------------------';    }  }}?>

資料庫：

使用者回複關鍵字，然後查詢回複相應圖文資訊。

1》根據期數進行查詢：

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;
