HTTP and HTTPS
PHP 3, PHP4, PHP 5. https://since PHP4.3.0
Allows read-only access to files/resources via HTTP 1.0, using the HTTP GET method. A Host: header is sent with the request to handle name-based virtual hosts. If you have configured a user_agent string using your ini file or the stream context, it will also be included in the request.
Внимание |
При использовании SSL,
Microsoft IIS нарушает протокол, закрывая соединение без отправки индикатора close_notify. PHP сообщит об этом как о "SSL: Fatal Protocol Error" в тот момент, когда вы достигнете конца данных. Чтобы обойти это, вы должны установить error_reporting на уровень, исключающий E_WARNING. PHP версий 4.3.7 и старше умеет определять, что на стороне сервера находится проблемный IIS и не выводит предупреждение. Если вы используете fsockopen() для создания ssl://сокета, вы сами отвечаете за определение и подавление этого предупреждения. |
Redirects have been supported since PHP4.0.5; if you are using an earlier version you will need to include trailing slashes in your URLs. If it's important to know the URL of the resource where your document came from (after all redirects have been processed), you'll need to process the series of response headers returned by the stream.
|
The stream allows access to the body of the resource; the headers are stored in the $http_response_header variable. Since PHP4.3.0, the headers are available using stream_get_meta_data().
HTTP connections are read-only; you cannot write data or copy files to an HTTP resource.
Замечание:HTTPS is supported starting from PHP4.3.0, if you have compiled in support for OpenSSL.

Таблица M-3. Context options
Name | Usage | Default |
---|---|---|
method | - GET, POST, or any other HTTP method supported by the remote server. | GET |
header | Additional headers to be sent during request. Values in this option will override other values (such as User-agent:, Host:, and Authentication:). | |
user_agent | Value to send with User-Agent: header. This value will only be used if user-agent is not specified in the header context option above. | - php.ini setting: user_agent |
content | - Additional data to be sent after the headers. Typically used with POST or PUT requests. | |
proxy | - URI specifying address of proxy server. (e.g. tcp://proxy.example.com:5100). | |
request_fulluri | - When set to TRUE, the entire URI will be used when constructing the request. (i.e. GET http://example.com/path/to/file.html HTTP/1.0). While this is a non-standard request format, some proxy servers require it. | FALSE |
max_redirects | - The max number of redirects to follow. Added in PHP 5.1.0. | 20 |
Underlying socket stream context options: Additional context options may be supported by the underlying transport For http://streams, refer to context options for the tcp://transport. For https://streams, refer to context options for the ssl://transport.
