Foreach循环仅保存最后的数组值，但是var_dump显示不同的结果

问题描述

我正在尝试使用foreach从循环中保存最后一个数组

根据每个$ keyword的逻辑，只要$ threadcount不满足$ maxthread，它将设置所有需要的变量，然后调用$ google-> getbrowser，然后将数组变量从$ google-> getbrowser保存到$ bparr >

变量$ bparr [$ keyword]仅显示$ google-> getbrowser（）中的最后一个数组变量，而var_dump（$ google-> getbrowser）正确显示

如何将每个$ google-> getbrowser结果添加到$ bparr中，而不仅仅是最后一个结果？

if ($multi)
{
    $threadcount = 0;
    $e = 0;
    $i = 0;
    $page = 1;
    $proxy = array();
    $browser = array();
    $uafilearr = array();
    $cfarr = array();
    $browser = $google->getbrowser();
    foreach ($keywords as $keyword)
    {
        // setup browser option as array
        if($threadcount < $maxthreads)
        {
            if (!empty($pfile))
            {
                $proxy[$keyword] = proxySetup($pfile);
                // explode the proxy to find out if there is username and password
                // usually there is 4 array_count if there is username and password
                $exproxy = explode(":",$proxy[$keyword]);
            
                if (count($exproxy) == 2)
                {
                    $proxyip = $exproxy[0].":".$exproxy[1];
                    $browser->setProxy($proxyip);
                    $browser->setProxyAuth('');
                }
    
                if (count($exproxy) == 4)
                {
                    $proxyip = $exproxy[0].":".$exproxy[1];
                    $proxyauth = $exproxy[2].":".$exproxy[3];
                    $browser->setProxy($proxyip);
                    $browser->setProxyAuth($proxyauth);
                }
            }
            if (!empty($cookiesdir))
            {
                clearstatcache();
                $uafile = $cookiesdir.'\gtu-'.md5($proxy[$keyword]).'.txt';
                $uafilearr[$keyword] = $uafile;
                if (file_exists($uafile)) {
                    $useragent = file_get_contents($uafile);                    
                }
                else
                {
                    touch($uafile);
                    if (!empty($agentfile))
                    {
                        $useragent = agent($agentfile);
                    }
                    else
                    {
                        // you can change the useragent defined here
                        $useragent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/84.0.4147.105 Safari/537.36";
                    }
                    file_put_contents($uafile,$useragent);

                }
                $browser->setUserAgent($useragent);
        
                $cookiesfile = $cookiesdir.'\gtc-'.md5($proxy[$keyword]).'.txt';
                $cfarr[$keyword] = $cookiesfile;
                if (!file_exists($cookiesfile)) {               
                    touch($cookiesfile);
                }
                $browser->setCookieFile($cookiesfile);
            }
            var_dump($google->getbrowser());
            if( !isset($bparr[$keyword])) $bparr[$keyword] = array();
            $bparr[$keyword] = $google->getbrowser();
        }
        else
        {
            break 1;
        }
        $threadcount++;
        
    }
    echo "proxy array\n";
    var_dump($proxy);
    echo "\n";
    echo "useragent array\n";
    var_dump($uafilearr);
    echo "\n";
    echo "cookies array\n";
    var_dump($cfarr);
    echo "\n";
    echo "\n";
    echo "browser array\n";
    var_dump($bparr);
    echo "\n";
}

下面是var_dump（$ google-> getbrowser（））;

的结果

解决方法

如果查看Browser类源代码here，您会发现getBrowser()方法未返回Class的新实例，而是返回了对它是自己的财产，其中包含另一个Object：

public function getBrowser()
{
    return $this->browser;
}

因此，每次将$google->getBrowser()添加到数组时，实际上就添加了对同一对象的引用。因此，您在这里有许多对同一Object的引用。

当您在脚本末尾调用var_dump时-它显示了相同对象的许多输出（很明显是相同的）。

请看官方Objects and references文章，以更好地理解引用的工作原理。

解决方案：

要解决您的情况，您只需在每次需要使用Object将clone保存到阵列时就克隆$bparr[$keyword][] = clone $google->getBrowser(); ：
