PHP curl抓取网页内容

备忘代码，随拿随用。

function curl_get_contents($url)
{ 
    /*设置头部信息，模拟登陆*/
    $headers[] = "User-Agent: Mozilla/5.0 (compatible; Baiduspider/2.0; +http://www.baidu.com/search/spider.html)";
    $curl = curl_init(); // 启动一个CURL会话
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HEADER, 0);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION,1);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);  // 跳过证书检查
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);  // 从证书中检查SSL加密算法是否存在
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    $tmpInfo = curl_exec($curl);     
    //关闭URL请求
    curl_close($curl);
    return $tmpInfo;
}
