Php文件停止工作

Php文件停止工作,php,Php,突然,我的php文件get给了我一个503错误。有人知道原因吗?还有其他方法吗 php $URL = "http://www.website.com/foo.html"; $a =file_get_contents("$URL"); echo ($a); Sol 1: Sol 2: 使用PHP中的此类命令,您可以在它们前面加上@以抑制此类警告 @file_get_contents('http://somenotrealurl.com/notrealpage'); file\u get\u

突然,我的php文件get给了我一个503错误。有人知道原因吗?还有其他方法吗

php $URL = "http://www.website.com/foo.html"; 
$a =file_get_contents("$URL"); echo ($a); 
Sol 1:

Sol 2:

使用PHP中的此类命令,您可以在它们前面加上@以抑制此类警告

@file_get_contents('http://somenotrealurl.com/notrealpage');
file\u get\u contents()
如果出现故障,则返回FALSE,因此如果您对照返回的结果检查,则可以处理故障

$pageDocument = @file_get_contents('http://somenotrealurl.com/notrealpage');

if ($pageDocument === false) {
    // Handle error
}
Sol 3:

虽然file_get_内容非常简洁方便,但为了更好地控制,我倾向于使用Curl库。这里有一个例子

function fetchUrl($uri) {
    $handle = curl_init();

    curl_setopt($handle, CURLOPT_URL, $uri);
    curl_setopt($handle, CURLOPT_POST, false);
    curl_setopt($handle, CURLOPT_BINARYTRANSFER, false);
    curl_setopt($handle, CURLOPT_HEADER, true);
    curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($handle, CURLOPT_CONNECTTIMEOUT, 10);

    $response = curl_exec($handle);
    $hlength  = curl_getinfo($handle, CURLINFO_HEADER_SIZE);
    $httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);
    $body     = substr($response, $hlength);

    // If HTTP response is not 200, throw exception
    if ($httpCode != 200) {
        throw new Exception($httpCode);
    }

    return $body;
}

$url = 'http://some.host.com/path/to/doc';

try {
    $response = fetchUrl($url);
} catch (Exception $e) {
    error_log('Fetch URL failed: ' . $e->getMessage() . ' for ' . $url);
}

你确定你有一个正确的URL吗?HTTP代码503是“服务暂时不可用”的代码。
也许可以使用函数
get_headers($url)进行检查

如果答案为已接受,则可以将其标记为已接受。
function fetchUrl($uri) {
    $handle = curl_init();

    curl_setopt($handle, CURLOPT_URL, $uri);
    curl_setopt($handle, CURLOPT_POST, false);
    curl_setopt($handle, CURLOPT_BINARYTRANSFER, false);
    curl_setopt($handle, CURLOPT_HEADER, true);
    curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($handle, CURLOPT_CONNECTTIMEOUT, 10);

    $response = curl_exec($handle);
    $hlength  = curl_getinfo($handle, CURLINFO_HEADER_SIZE);
    $httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);
    $body     = substr($response, $hlength);

    // If HTTP response is not 200, throw exception
    if ($httpCode != 200) {
        throw new Exception($httpCode);
    }

    return $body;
}

$url = 'http://some.host.com/path/to/doc';

try {
    $response = fetchUrl($url);
} catch (Exception $e) {
    error_log('Fetch URL failed: ' . $e->getMessage() . ' for ' . $url);
