A PHP general collection class based on phpQuery sharing_PHP tutorial

1. Collection source code

Copy the code The code is as follows:

  /**
*General list collection class
*Version V1.3
*Author: JAE
*/
    require_once '../phpQuery/phpQuery/phpQuery.php';
    class QueryList{

        private $pageURL;
         private $regArr = array();
         public $jsonArr = array();
         private $regRange;
         private $html;
         /**************************************************
* Parameters: Page address selector array block selector
* [Selector array] Description: Format array("name"=>array("selector","type"),.....)
           * [Type] Description: Values ​​"text", "html", "attribute" Choice
********************************************* ****/
         function QueryList($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:

require 'Query/QueryList.class.php';

//Collect OSC code sharing list, title link author
$url = "http://www.oschina.net/code/list";
$reg = array("title "=>array(".code_title a:eq(0)","text"),"url"=>array(".code_title a:eq(0)","href"),"author"= >array("img","title"));
$rang = ".code_list li";
$hj = new QueryList($url,$reg,$rang);
$arr = $hj->jsonArr;
print_r($arr);
//If you also want to collect the TOP40 active contributor images on the right side of the current page and get the JSON data, you can write like this
$reg = array ("portrait"=>array(".hot_top img","src"));
$hj->setQuery($reg);
$json = $hj->getJSON();
echo $json . "

---

";

//Collect the content of OSC content page
$url = "http://www.oschina.net/code/snippet_186288_23816";
$reg = array("title"=>array(". QTitle h1","text"),"con"=>array(".Content","html"));
$hj = new QueryList($url,$reg);
$arr = $hj->jsonArr;
print_r($arr);

//Just give so many examples, is it very convenient to use for collection?
