如何使用Google Analytics（分析）獲得訪問者的數量

Question

如您所見，有什么方法可以避免代碼中的鏈接重復

$gaUrl['devices'] = "&start-date=$this->startdate&end-date=$this->enddate&metrics=".$gaQuery['devices']['metrics']."&dimensions=".$gaQuery['devices']['dimensions']."&sort=".$gaQuery['devices']['sort'];
    $gaUrl['keywords'] = "&start-date=$this->startdate&end-date=$this->enddate&metrics=".$gaQuery['keywords']['metrics']."&dimensions=".$gaQuery['keywords']['dimensions']."&sort=".$gaQuery['keywords']['sort'];
    $gaUrl['countries'] = "&start-date=$this->startdate&end-date=$this->enddate&metrics=".$gaQuery['countries']['metrics']."&dimensions=".$gaQuery['countries']['dimensions']."&sort=".$gaQuery['countries']['sort'];
    $gaUrl['destinations'] = "&start-date=$this->startdate&end-date=$this->enddate&metrics=".$gaQuery['destinations']['metrics']."&dimensions=".$gaQuery['destinations']['dimensions']."&sort=".$gaQuery['destinations']['sort'];
    $gaUrl['currentTrafficSrc'] = "&start-date=$this->startdate&end-date=$this->enddate&metrics=".$gaQuery['currentTrafficSrc']['metrics']."&dimensions=".$gaQuery['currentTrafficSrc']['dimensions']."&sort=".$gaQuery['currentTrafficSrc']['sort'];
    // Visits
    $gaUrl['cuurentMonthVisits'] = "&start-date=$this->startdate&end-date=$this->enddate&metrics=".$gaQuery['cuurentMonthVisits']['metrics'];
    $gaUrl['lastMonth'] = "&start-date=$this->startdate&end-date=$this->enddate&metrics=".$gaQuery['cuurentMonthVisits']['metrics'];

我認為你應該只用一個變量替換鏈接

$l = "&start-date=$this->startdate&end-date=$this->enddate&metrics=";
$gaUrl['devices'] = $l.$gaQuery['devices']['metrics']."&dimensions=".$gaQuery['devices']['dimensions']."&sort=".$gaQuery['devices']['sort'];
$gaUrl['keywords'] = $l.$gaQuery['keywords']['metrics']."&dimensions=".$gaQuery['keywords']['dimensions']."&sort=".$gaQuery['keywords']['sort'];
