    source :
    Code:
    https://www.blackhatworld.com/seo/php-proxy-rotation.910239/
    class rotateproxy.php :
    Code:
    <?php
    
    Class RotateProxy{
        private $proxy = '';
        private $fp = '';
        private $list = array();
        private $counter; //number of times proxy used. Default is 1
        private $current; //number of times proxy HAS been used.
       
        public function __constructor($path,$counter=1){
            $this->list = trim(file($path));
            $this->$counter = $counter;
        }
       
        public function getProxy(){
            if($this->current > $this->counter){
                array_shift($this->list);
               
                $this->current = 1;
               
                $this->proxy = $this->list[0];
               
                return $this->proxy;
            }else{
                $this->current++;
                return $this->proxy;
            }
        }
    }
    ?>
    CONTOH grab.php :
    Code:
    <?PHP
    require_once('path/to/rotateproxy.php'); //The above class.
    $url = 'http://somesite.com';
    $proxylist = __DIR__ . 'proxies.txt'; // just an example.
    
    /*********
    ** $counter is how many times the proxy can be used before it is discarded. Defaults to 1.
    */
    $counter = 5; // proxy will be used 5 times before moving to the next proxy.
    $rotate = new RotateProxy($proxylist,$counter);
    
    while(SomeAction){
        $proxy = $rotate->getProxy();
    
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,$url);
        curl_setopt($ch, CURLOPT_PROXY, $proxy);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_HEADER, 1);
        $curl_scraped_page = curl_exec($ch);
        curl_close($ch);
        echo $curl_scraped_page;
    }
    
    ?>
    yang jadi pertanyaan, ketika saya gabungkan dengan scrip graber yang udah ada
    jadi:
    Code:
    <?php
    require_once('rotateproxy.php'); //The above class.
    $url = 'http://somesite.com';
    $proxylist = __DIR__ . '/proxies.txt'; // just an example.
    
    /*********
    ** $counter is how many times the proxy can be used before it is discarded. Defaults to 1.
    */
    $counter = 1; // proxy will be used 5 times before moving to the next proxy.
    $rotate = new RotateProxy($proxylist,$counter);
    
    function get_contents($url, $referer = 'http://www.google.com/firefox?client=firefox-a&rls=org.mozilla:fr:official', $ua = 'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.18) Gecko/20110614 Firefox/3.6.18') {
    if(function_exists('curl_exec')) {
     $proxy = $rotate->getProxy();
     $curl = curl_init();
     $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,";
     $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";
     $header[] = "Cache-Control: max-age=0";
     $header[] = "Connection: keep-alive";
     $header[] = "Keep-Alive: 300";
     $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7";
     $header[] = "Accept-Language: en-us,en;q=0.5";
     $header[] = "Pragma: ";
     curl_setopt($curl, CURLOPT_URL, $url);
     curl_setopt($curl, CURLOPT_PROXY, $proxy);
     curl_setopt($curl, CURLOPT_USERAGENT, $ua);
     curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
     curl_setopt($curl, CURLOPT_REFERER, $referer);
     curl_setopt($curl, CURLOPT_ENCODING, 'gzip,deflate');
     curl_setopt($curl, CURLOPT_AUTOREFERER, true);
     curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
     curl_setopt($curl, CURLOPT_TIMEOUT, 10);
     $content = curl_exec($curl);
     curl_close($curl);
     } else {
     ini_set('user_agent', $ua);
     $content = file_get_contents($url);
     }
     return $content;
    }
    ?>
    hasilnya error : Call to a member function getProxy() on a non-object in grab.php on line 190
    dimana line 190 adalah $proxy = $rotate->getProxy();

    sedangkan kalau tanpa tambahan script proxy rotation, skrip grab berjalan sempurna.

    mohon solusinya para mastah php

    coba pakai ini gan
    PHP:
    function curlDong($url,$proxy='',$proxyauth=''){

        
    $ch=curl_init();
      
        
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
        
    curl_setopt($ch,CURLOPT_URL,$url);    // URL for CURL call
      
        
    if(!empty($proxy))curl_setopt($chCURLOPT_PROXY$proxy);
        if(!empty(
    $proxyauth))curl_setopt($chCURLOPT_PROXYUSERPWD$proxyauth);
      
        
    curl_setopt($chCURLOPT_PROXYTYPECURLPROXY_SOCKS5);
      
        
    $cx=curl_exec($ch);
        
    curl_close($ch);
        return(
    $cx);
     
    }

    //pemakaian
    $isinya curlDong($urlnya,$proxyPortnya,'usernamenya:passwordnya');

    seharusnya ga ada masalah sih gan (sudah sy coba sendiri jg ga ada masalah). klo boleh tau agan masukin potongan kode itu ke framework atau native?
    klo ke framework mungkin pengaruh case-sensitive nama file & penamaan class.

    itu var $rotate dalam function get_contents masih null
    cmiiw

    ganti jadi gini gan:
    function get_contents($rotate,$url, ....{
    ...
    }

    terus make nya :
    get_contents($rotate,....);
