file_get_contents的超时在PHP中不起作用

我创建了一个类来在PHP中使用一些HTTP方法.在这里,我有一个HTTP POST的方法

public function post ($content, $timeout=null)
{
    $timeInit = new DateTime();

    $this->method = 'POST';


    $header = array();
    $header['header'] = null;
    $header['content'] = is_array($content) ? http_build_query($content) : $content;
    $header['method'] = $this->method;
    if ($timeout != NULL) {
        $header['header'] .= "timeout: $timeout"
    }
    $header['header'] .= "Content-length: ".strlen($header['content']);


    $headerContext =  stream_context_create(array('http' => $header));
    $contents = file_get_contents($this->url, false, $headerContext);
    $this->responseHeader = $http_response_header;

    $timeFinal = new DateTime();
    $this->time = $timeInit->diff($timeFinal);

    return $contents;
}

基本上,我创建了一个$header并使用file_get_contents将一些$content发布到URL中.
显然,除了$timeout之外,一切正常.它不被考虑.例如,即使我将其设置为1.

我没有看到任何错误,我无法得到我正在发送的标题.

SO中的其他类似问题建议使用Curl(我正在使用它,但由于其他原因我正在更改file_get_contents)或fsockopen,但这不是我需要的.

存在一些使用file_get_contents设置超时的方法？

解决方法:

对于stream_context_create()http://php.net/manual/en/function.stream-context-create.php,它需要[array $options [,array $params]]
当你传递$header时,看起来你没有正确构建数组.会不会像这样的工作？

public function myPost($content, $timeout = null)
{
    $timeInit = new DateTime();

    $this->method = 'POST';


    $header = array();
    $header['header'] = null;
    $header['content'] = is_array($content) ? http_build_query($content) : $content;
    $header['method'] = $this->method;

    if ($timeout) {
        $header['header']['timeout'] = $timeout;
    }

    $header['header']['Content-length'] . strlen($header['content']);
    $headerContext = stream_context_create(array('http' => $header));
    $contents = file_get_contents($this->url, false, $headerContext);
    $this->responseHeader = $http_response_header;

    $timeFinal = new DateTime();
    $this->time = $timeInit->diff($timeFinal);

    return $contents;
}

但更好的方法是使用它,如例子所示,例如,

$timeInit = new DateTime();

// all your defaults go here
$opts = array(
    'http'=>array(
        'method'=>"POST",
    )
);

//this way, inside conditions if you want
$opts['http']['header']  = "Accept-language: en\r\n" .  "Cookie: foo=bar\r\n";
$context = stream_context_create($opts);
