一个基于phpQuery的php通用采集类分享

一、采集类源码

复制代码 代码如下:


<?php
  /**
  *通用列表采集
  *版本V1.3
  *作者:JAE
  */
    require_once '../phpQuery/phpQuery/phpQuery.php';
    class QueryList{

        private $pageURL;
         private $regArr = array();
         public $jsonArr = array();
         private $regRange;
         private $html;
         /************************************************
         * 参数: 页面地址 选择器数组 块选择器
         * 【选择器数组】说明:格式array("名称"=>array("选择器","类型"),.......)
         * 【类型】说明:值 "text" ,"html" ,"属性"
         *【块选择器】:指 先按照规则 选出 几个大块 ,然后再分别再在块里面 进行相关的选择
         *************************************************/
         function QueryList($pageURL,$regArr=array(),$regRange='')
         {
             $this->pageURL = $pageURL;

             //为了能获取https://
               $ch = curl_init();
                curl_setopt($ch, CURLOPT_URL,$this->pageURL);
                curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
                curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
                curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
                $this->html = curl_exec($ch);
               curl_close($ch);

             if(!empty($regArr))
             {

                  $this->regArr = $regArr;
                 $this->regRange = $regRange;
                 $this->getList();
             }

         }
         function setQuery($regArr,$regRange='')
         {
             $this->jsonArr=array();
             $this->regArr = $regArr;
             $this->regRange = $regRange;
             $this->getList();
         }
        private function getList()
         {

             $hobj = phpQuery::newDocumentHTML($this->html);
             if(!empty($this->regRange))
             {
             $robj = pq($hobj)->find($this->regRange);

              $i=0;
             foreach($robj as $item)
             {

                 while(list($key,$reg_value)=each($this->regArr))
                 {
                     $iobj = pq($item)->find($reg_value[0]);

                       switch($reg_value[1])
                       {
                           case 'text':
                                 $this->jsonArr[$i][$key] = trim(pq($iobj)->text());
                                 break;
                           case 'html':
                                 $this->jsonArr[$i][$key] = trim(pq($iobj)->html());
                                 break;
                           default:
                                $this->jsonArr[$i][$key] = pq($iobj)->attr($reg_value[1]);
                                break;

                        }
                 }
                 //重置数组指针
                 reset($this->regArr);
                 $i++;
              }
             }
             else
             {
            while(list($key,$reg_value)=each($this->regArr))
             {
                $lobj = pq($hobj)->find($reg_value[0]);

                  
                   $i=0;
                   foreach($lobj as $item)
                   {
                       switch($reg_value[1])
                       {
                           case 'text':
                                 $this->jsonArr[$i++][$key] = trim(pq($item)->text());
                                 break;
                           case 'html':
                                 $this->jsonArr[$i++][$key] = trim(pq($item)->html());
                                 break;
                           default:
                                $this->jsonArr[$i++][$key] = pq($item)->attr($reg_value[1]);
                                break;

                        }

                    
                   }

       
             }
           }
         } 
         function getJSON()
         {
             return json_encode($this->jsonArr);
         }

}

二、使用例子

复制代码 代码如下:


<?php
require 'Query/QueryList.class.php';
