这个版本为我工作，删除了oo

$url = 'http://www.jiwlp.com';

if(isset($url)){
$ch = curl_init();
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);
    curl_setopt($ch,CURLOPT_BINARYTRANSFER,$binary);

    $useragent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
 rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1";
    curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,true);
    curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false);
    curl_setopt($ch,CURLOPT_VERBOSE,1);
    curl_setopt($ch,CURLOPT_USERAGENT,$useragent);
    curl_setopt($ch,CURLOPT_TIMEOUT,5);
    curl_exec($ch);
    $status = curl_getinfo($ch,CURLINFO_HTTP_CODE);
    print_r(curl_getinfo($ch));
    curl_close($ch);
}

响应状态已经存储在$this->status中，我假设您指的是HTTP响应状态代码，因此，

// grabs the webpage from the internet 
$this->html = curl_exec($this->ch);  
$this->status = curl_getinfo($this->ch, CURLINFO_HTTP_CODE);

print_r(curl_getinfo($this->ch));

请尝试打印$this->status。

// grabs the webpage from the internet 
$this->html = curl_exec($this->ch);  
$this->status = curl_getinfo($this->ch, CURLINFO_HTTP_CODE);

print_r($this->status);

在php禁用函数中检查CURL。
如果CURL_EXEC在网络服务器中被禁用，php将不会给予错误，而是将[http_code] =〉0 header_size] =〉0 ....
从一个php页面运行phpinfo（）是一种获取被禁用php函数列表的方法。

我使用这个函数来获取http站点/链接状态：

<?php
function get_link_status($url, $timeout = 10) 
{
$ch = curl_init();
// set cURL options
$opts = array(CURLOPT_RETURNTRANSFER => true, // do not output to browser
            CURLOPT_URL => $url,            // set URL
            CURLOPT_NOBODY => true,         // do a HEAD request only
            CURLOPT_TIMEOUT => $timeout);   // set timeout
curl_setopt_array($ch, $opts);
curl_exec($ch); // do it!
$status = curl_getinfo($ch, CURLINFO_HTTP_CODE); // find HTTP status
curl_close($ch); // close handle
echo $status; //or return $status;
    //example of check
    if ($status == '301') { echo 'This is redirected';}
}

get_link_status('http://example.com');
?>
