php廣告載入類用法執行個體，php載入用法執行個體

本文執行個體講述了php廣告載入類的用法，非常實用。分享給大家供大家參考。具體方法如下：

該php廣告載入類，支援非同步與同步載入。需要使用Jquery實現。

ADLoader.class.php類檔案如下：

<?php /** 廣告載入管理類 *  Date:  2013-08-04 *  Author: fdipzone *  Ver:  1.0 * *  Func: *  public load     載入廣告集合 *  public setConfig  廣告配置 *  private getAds    根據channel建立廣告集合 *  private genZoneId  zoneid base64_encode 處理 *  private genHtml   產生廣告html *  private checkBrowser 檢查是否需要同步載入的瀏覽器 */  class ADLoader{ // class start    private static $_ads = array();   // 廣告集合   private static $_step = 300;    // 廣告載入間隔   private static $_async = true;   // 是否非同步載入   private static $_config = array(); // 廣告設定檔案   private static $_jsclass = null;  // 廣告JS class     /** 載入廣告集合   * @param String $channel 欄目,對應config檔案   * @param int   $step  廣告載入間隔   * @param boolean $async  是否非同步載入   */   public static function load($channel='', $step='', $async=''){     if(isset($step) && is_numeric($step) && $step>0){       self::$_step = $step;     }      if(isset($async) && is_bool($async)){       self::$_async = $async;     }      // 判斷瀏覽器,如IE強制使用同步載入     if(!self::checkBrowser()){       self::$_async = false;     }      self::getAds($channel);     self::genZoneId();      return self::genHtml();   }    /** 設定config   * @param String $config 廣告配置   * @param String $jsclass js class檔案路徑   */   public static function setConfig($config=array(), $jsclass=''){     self::$_config = $config;     self::$_jsclass = $jsclass;   }     /** 根據channel建立廣告集合   * @param String $channel 欄目   */   private static function getAds($channel=''){     $AD_Config = self::$_config;     if($AD_Config!=null){       self::$_ads = isset($AD_Config[$channel])? $AD_Config[$channel] : $AD_Config['default'];     }   }    /** zoneid base64_encode 處理 */   private static function genZoneId(){      // 同步載入廣告不需要處理zoneid     if(!self::$_async){       return ;     }      $ads = self::$_ads;     for($i=0,$len=count($ads); $i<$len; $i++){       if(isset($ads[$i]['zoneId'])){         $ads[$i]['zoneId'] = base64_encode('var zoneid='.$ads[$i]['zoneId'].';');       }     }     self::$_ads = $ads;   }    /** 產生廣告html */   private static function genHtml(){     $ads = self::$_ads;     $html = array();     if(self::$_jsclass!=null && $ads){       array_push($html, '');        // 同步需要積極式載入       if(!self::$_async){         foreach($ads as $ad){           array_push($html, '');           array_push($html, '');           array_push($html, '');         }       }        array_push($html, '');     }     return implode("\r\n", $html);   }    /** 判斷是否需要強制同步載入的瀏覽器 */   private static function checkBrowser(){     $user_agent = $_SERVER['HTTP_USER_AGENT'];     if(strstr($user_agent,'MSIE')!=''){       return false;     }     return true;   }  } // class end ?>

ADConfig.php檔案如下：

<?php /** 廣告設定檔 **/  return array(    'case_openx' => array(     array(       'type' => 'openx',       'domId' => 'ad_728x90',       'zoneId' => 452     ),     array(       'type' => 'openx',       'domId' => 'ad_300x250',       'zoneId' => 449     ),     array(       'type' => 'openx',       'domId' => 'ad_l2_300x250',       'zoneId' => 394     ),   ),    'case_url' => array(     array(       'type' => 'url',       'domId' => 'ad_728x90',       'url' => 'adurl.php?zoneid=452'     ),     array(       'type' => 'url',       'domId' => 'ad_300x250',       'url' => 'adurl.php?zoneid=449'     ),     array(       'type' => 'url',       'domId' => 'ad_l2_300x250',       'url' => 'adurl.php?zoneid=394'     )   ),    'case_sync_openx' => array(     array(       'type' => 'openx',       'domId' => 'ad_728x90',       'zoneId' => 452     ),     array(       'type' => 'openx',       'domId' => 'ad_300x250',       'zoneId' => 449     ),     array(       'type' => 'openx',       'domId' => 'ad_l2_300x250',       'zoneId' => 394     ),   ),    'default' => array(     array(       'type' => 'openx',       'domId' => 'ad_728x90',       'zoneId' => 452     ),     array(       'type' => 'openx',       'domId' => 'ad_300x250',       'zoneId' => 449     ),     array(       'type' => 'openx',       'domId' => 'ad_l2_300x250',       'zoneId' => 394     ),   ),  );  ?>

ADLoader.js檔案如下：

adurl.php檔案如下：
