PHP自己封装改良的curl分享

话不多说直接上代码：

 function curl($url, $paras=[]){ 
$paras = array_change_key_case($paras, CASE_LOWER); //键名全部转小写
$dl_ip=array("8.142.171.2","114.132.79.2");

shuffle($dl_ip); if($paras['daili']){ $url='http://'.$dl_ip[0] .'/?url='.urlencode($url); 
$paras['post']=$paras; $paras['post']=array_merge($paras['post'],['daili_status'=>1]); unset($paras['post']['daili'],$paras['header']); }
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
if(empty($paras['header'])){ $Header=array();
   $Header[] = "Accept: */*";
	$Header[] = "Accept-Encoding: gzip,deflate,sdch";
	$Header[] = "Accept-Language: zh-CN,zh;q=0.8";
	$Header[] = "Connection: close";
}else{ //模拟Header，建议上方格式
if(!is_array($paras['header'])&&strpos($paras['header'],"\n")!==false){
$Header=explode("\n", trim($paras['header'],"\n") ); 
}else{ $Header=$paras['header']; } }
//print_r($Header);
if($paras['ip']){ //伪造IP
if(!filter_var($paras['ip'], FILTER_VALIDATE_IP)){ $paras['ip']="14.".rand(1,255).'.'.rand(1,255).'.'.rand(1,255); }
$ip_arr=['X-FORWARDED-FOR:'.$paras['ip'],'CF-CONNECTING-IP:'.$paras['ip'] ];
$Header=array_merge($Header,$ip_arr); }//数组融合
    curl_setopt($ch, CURLOPT_HTTPHEADER, $Header);
    if ($paras['ctime']) { // 连接超时
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $paras['ctime']);
    } else { curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10); }
    if ($paras['rtime']) { // 读取超时
        curl_setopt($ch, CURLOPT_TIMEOUT, $paras['rtime']);
    }
    
 if(!$paras['loadurl']){ curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); }//默认跟随跳转抓取
    
    if ($paras['post']) { //POST提交
//'post'=>'id=1&key=key'或者'post'=>[ 1=>'内容',]，第二种键名必须对上号，有些网址不允许数组方式
if(is_array($paras['post'])){ $paras['post']=http_build_query($paras['post']); } //若为数组，则执行参数拼接，防止有些头部固定这种格式
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $paras['post']); }
    if ($paras['get_header']){ curl_setopt($ch, CURLOPT_HEADER, true); }//查看返回Header信息
if($paras['cookie']) { //携带Cookie，必须用;分隔
if(is_array($paras['cookie'])){ $cookie='';  foreach($paras['cookie'] as $key=>$value){ 
if(preg_match('/^\d+$/', $key)&&mb_strlen($key,'utf8')<=2){ $cookie.=$value.'; '; 
}else{ $cookie.=$key.'='.$value.'; '; }  } //有些需要urlencode编码格式
//exit($cookie);
}else{ $cookie=$paras['cookie']; }
        curl_setopt($ch, CURLOPT_COOKIE, $cookie);
    }
    if ($paras['refer']) { //伪造来访网址
        if ($paras['refer'] == 1) {
            curl_setopt($ch, CURLOPT_REFERER, 'http://m.qzone.com/infocenter?g_f=');
        } else {
            curl_setopt($ch, CURLOPT_REFERER, $paras['refer']);
        }
    }
    if ($paras['ua']) {  //伪造UA
        curl_setopt($ch, CURLOPT_USERAGENT, $paras['ua']); 
    } else {

    }
    if ($paras['nobody']&&!$paras['daili']) { //不返回网页源代码信息
        curl_setopt($ch, CURLOPT_NOBODY, 1);
    }
    curl_setopt($ch, CURLOPT_ENCODING, "gzip");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    
    if (($paras['getcookie']||$paras['get_cookie'])&&!$paras['daili']) {  //获取请求的全部信息
        curl_setopt($ch, CURLOPT_HEADER, 1);
        $result = curl_exec($ch);
        preg_match_all("/Set-Cookie: (.*?);/m", $result, $matches);

"Cookie"=>$matches,"cookie"=>$matches, "body" => $body, "header" => $header, 'code' => curl_getinfo($ch, CURLINFO_HTTP_CODE), //code是响应状态码
        ]; curl_close($ch);
        if($paras['daili_status']){ return json_encode($ret);  }
        return $ret; }
        
    $ret = curl_exec($ch);

    $Headers = curl_getinfo($ch);

    } else { $ret = false; }  }
    curl_close($ch); 
if(($paras['getcookie']||$paras['get_cookie'])&&$paras['daili']){ $ret=json_decode($ret,true);
 $ret=array_merge($ret,['dl_ip'=>$dl_ip[0]]);   return $ret;  } //显示代理IP
    return $ret; }

使用示例：

$data=curl('https://www.yuanxiapi.cn/',[
'GetCookie'=>'1',
'nobody'=>1
    ]);
echo $data['code'];

其它示例我就不一一说了，懂的自然都懂。
