經常需要判斷文件是否可以訪問,可以通過http狀態碼判別,200為正常訪問,404為找不到該頁面,代碼如下:

// 設置url

$url = 'http://m.survivalescaperooms.com';

function get_http_status_code($url) {

if(emptyempty($url)) return false;

$url = parse_url($url);

$host = isset($url['host']) ? $url['host'] : '';

$port = isset($url['port']) ? $url['port'] : '80';

$path = isset($url['path']) ? $url['path'] : '';

$query = isset($url['query']) ? $url['query'] : '';

$request = "HEAD $path?$query HTTP/1.1rn"

           ."Host: $hostrn"

           ."Connection: closern"

           ."rn";

$address = gethostbyname($host);

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

socket_connect($socket, $address, $port);

socket_write($socket, $request, strlen($request));

$response = split(' ', socket_read($socket, 1024));

socket_close($socket);

return  trim($response[1]);

}

echo get_http_status_code($url);

另一種獲取http狀態碼的辦法

使用curl需要在php.ini中設置啟用才行 >< Windows的服務器中,打開php.ini,找到:

extension=php_curl.dll

去掉前面的注釋既可.

PHP實例代碼如下:

$curl = curl_init();

$url=’http://m.survivalescaperooms.com’;

curl_setopt($curl, CURLOPT_URL, $url); //設置URL

curl_setopt($curl, CURLOPT_HEADER, 1); //獲取Header

curl_setopt($curl,CURLOPT_NOBODY,true); //Body就不要了吧，我們只是需要Head

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); //數據存到成字符串吧，別給我直接輸出到屏幕了

$data = curl_exec($curl); //開始執行啦～

echo curl_getinfo($curl,CURLINFO_HTTP_CODE); //我知道HTTPSTAT碼哦～

curl_close($curl); //用完記得關掉他
