PHP CURL验证代理池和使用代理

使用代理

//初始化 curl 乱七八糟就不写了
$arrip = [
    'xxx.x.xx.x:80',
    'xxx.x.xx.x:80',
    'xxx.x.xx.x:80',
];
//取出随机代-理
$daili = $arrip[array_rand($arrip, 1)];
$ip = explode(':', $daili)[0];
$port = explode(':', $daili)[1];
 
curl_setopt($ch, CURLOPT_PROXY, $ip);
curl_setopt($ch, CURLOPT_PROXYPORT, $port);
验证代理是否有效
