自己寫的一個php基於phpQuery的通用採集類

還是小菜，第一次分享代碼哈，這是自己以前寫的一個php的採集類，自己一直在用，自我感覺很簡單很強大，只要懂一點點選取器的知識就可以採集任何頁面了，也支援https頁面，做簡單的採集足夠用了。 /** *通用列表採集類 *版本V1.3 *作者:JAE *部落格:http://blog.jaekj.com */ require_once '../phpQuery/phpQuery/phpQuery.php'; class QueryList{ private $pageURL; private $regArr = array(); public $jsonArr = array(); private $regRange; private $html; /************************************************ * 參數: 頁面地址 選取器數組 塊選取器 * 【選取器數組】說明：格式array("名稱"=>array("選取器","類型"),.......) * 【類型】說明：值 "text" ,"html" ,"屬性" *【塊選取器】：指 先按照規則 選出 幾個大塊 ，然後再分別再在塊裡面 進行相關的選擇 *************************************************/ function QueryList($pageURL,$regArr=array(),$regRange='') { $this->pageURL = $pageURL; //為了能擷取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($reg_value[1]); break; } } //重設數組指標 reset($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); } } 複製代碼 require 'Query/QueryList.class.php'; //採集OSC的代碼分享列表，標題 連結 作者 $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); //如果還想采當前頁面右邊的 TOP40活躍貢獻者 映像，得到JSON資料,可以這樣寫 $reg = array("portrait"=>array(".hot_top img","src")); $hj->setQuery($reg); $json = $hj->getJSON(); echo $json .
