本文实例讲述了thinkphp 3.2框架视图模型 实例视图查询结果的二维数组合并操作。分享给大家供大家参考，具体如下：

使用视图模型查询的时候 结果是这样的

代码语言：javascript复制
array(6) {
 [0] =  array(5) {
  ["picTitle"] =  string(7) "标题2"
  ["picCategroy"] =  string(6) "海报"
  ["picAuthor"] =  string(12) "星耀学园"
  ["picPostTime"] =  string(19) "2014-11-26 11:59:50"
  ["pictureurl"] =  string(55) "attachment/picture/uploadify/20141126/547550278b7db.jpg"
 }
 [1] =  array(5) {
  ["picTitle"] =  string(7) "标题2"
  ["picCategroy"] =  string(6) "海报"
  ["picAuthor"] =  string(12) "星耀学园"
  ["picPostTime"] =  string(19) "2014-11-26 11:59:50"
  ["pictureurl"] =  string(55) "attachment/picture/uploadify/20141126/54755027ab89b.jpg"
 }
 [2] =  array(5) {
  ["picTitle"] =  string(7) "标题2"
  ["picCategroy"] =  string(6) "海报"
  ["picAuthor"] =  string(12) "星耀学园"
  ["picPostTime"] =  string(19) "2014-11-26 11:59:50"
  ["pictureurl"] =  string(55) "attachment/picture/uploadify/20141126/547550273b753.jpg"
 }
 [3] =  array(5) {
  ["picTitle"] =  string(7) "标题2"
  ["picCategroy"] =  string(6) "海报"
  ["picAuthor"] =  string(12) "星耀学园"
  ["picPostTime"] =  string(19) "2014-11-26 11:59:50"
  ["pictureurl"] =  string(55) "attachment/picture/uploadify/20141126/54755027d8488.jpg"
 }
 [4] =  array(5) {
  ["picTitle"] =  string(33) "同步写入信息和附件表里"
  ["picCategroy"] =  string(6) "海报"
  ["picAuthor"] =  string(12) "星耀学园"
  ["picPostTime"] =  string(19) "2014-11-20 16:05:16"
  ["pictureurl"] =  string(55) "attachment/picture/uploadify/20141120/546da0746edb8.png"
 }
 [5] =  array(5) {
  ["picTitle"] =  string(33) "同步写入信息和附件表里"
  ["picCategroy"] =  string(6) "海报"
  ["picAuthor"] =  string(12) "星耀学园"
  ["picPostTime"] =  string(19) "2014-11-20 16:05:16"
  ["pictureurl"] =  string(55) "attachment/picture/uploadify/20141120/546da0784831c.png"
 }
}

想要的结果是这样

代码语言：javascript复制
array(2) {
 ["0"] =  array(5) {
  ["picTitle"] =  string(7) "标题2"
  ["picCategroy"] =  string(6) "海报"
  ["picAuthor"] =  string(12) "星耀学园"
  ["picPostTime"] =  string(19) "2014-11-26 11:59:50"
  ["pictureurl"] =  string(223) "attachment/picture/uploadify/20141126/547550278b7db.jpg,attachment/picture/uploadify/20141126/54755027ab89b.jpg,attachment/picture/uploadify/20141126/547550273b753.jpg,attachment/picture/uploadify/20141126/54755027d8488.jpg"
 }
 ["1"] =  array(5) {
  ["picTitle"] =  string(33) "同步写入信息和附件表里"
  ["picCategroy"] =  string(6) "海报"
  ["picAuthor"] =  string(12) "星耀学园"
  ["picPostTime"] =  string(19) "2014-11-20 16:05:16"
  ["pictureurl"] =  string(111) "attachment/picture/uploadify/20141120/546da0746edb8.png,attachment/picture/uploadify/20141120/546da0784831c.png"
 }
}

完整实例开始

控制器 里 根据生成的SQL 语句在phpmyadmin里运行 出现排序规则不一致的情况 两个表的字段 排序规则不一致 整表排序规则一样的情况下

PictureController.class.php

代码语言：javascript复制
  public function Pic(){
     $PicModel =D('PicView');

    /* dump($PicModel);*/

    $s1= $PicModel- field('picTitle,picCategroy,picAuthor,picPostTime,pictureurl')- order('picPostTime desc')- select();
   /* dump($PicModel- getLastSql()); 查询最后的sql 语句*/
   /* dump($s1);*/
    $zhengli = $this- mergePictureURL($s1);
   /* dump( $zhengli );*/

    $this- assign("content",$zhengli);

    $this- display();

  }

视图模型里

PicViewModel.class.php

代码语言：javascript复制
<?php
namespace HomeModel;
use ThinkModelViewModel;
class PicViewModel extends ViewModel{
  public $viewFields =array(
    'Picture'=  array('picTitle','picToken','picCategroy','picAuthor','picPostTime','_as'= 'Picture'),
    'PictureAttachment' = array('pictureid','pictureurl','creattime','_on'= 'Picture.picToken = PictureAttachment.pictureid','_as'= 'PictureAttachment'),

  );
}

视图里

代码语言：javascript复制
<!DOCTYPE html 
<html 
<head lang="en" 
  <meta charset="UTF-8" 
  <title </title 
</head 
<body 
<volist name="content" id="data" 
 <!-- {$data.picTitle} {$data.picAuthor}发布时间：{$data.picPostTime}-- 
  {$data.picTitle}
</volist 
</body 
</html
