• php下获取http状态的实现代码


    在项目开发中,有时我们需要知道远程的URL地址是否能访问正常,判断其正常与否后进行下一步的操作,那么在PHP中如何获取远程HTTP的状态呢
     

    逐风整理了两种方式,大家可以自行参考/使用:

    复制代码 代码如下:

    #方式一
    $ch = curl_init('http://www.jb51.net');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_exec($ch);
    echo curl_getinfo($ch, CURLINFO_HTTP_CODE); // 200
    curl_close($ch);


    方式二

    复制代码 代码如下:


    print_r(
        get_headers('http://www.baidu.com')
    );
    #返回以下内容:
    /*
    Array   
    (   
    [0] => HTTP/1.1 200 OK   
    [1] => Date: Sun, 04 May 2014 03:43:04 GMT   
    [2] => Content-Type: text/html; charset=utf-8   
    [3] => Connection: Close   
    [4] => Vary: Accept-Encoding   
    [5] => Set-Cookie: BAIDUID=4977AF4FB1E9A5D13C79939E28D92161:FG=1; expires=Thu, 31-Dec-37 23:55:55 GMT; max-age=2147483647; path=/; domain=.baidu.com

    [8] => P3P: CP=" OTI DSP COR IVA OUR IND COM "   
    [9] => Cache-Control: private   
    [10] => Expires: Sun, 04 May 2014 03:42:09 GMT

    [14] => BDQID: 0x9acb602d00001922   
    [15] => BDUSERID: 0   
    )
