Package: Zend\Http\Client

Zend_Http_Client is an implementation of an HTTP client in PHP.

The client supports basic features like sending different HTTP requests and handling redirections, as well as more advanced features like proxy settings, HTTP authentication and cookie persistence (using a Zend_Http_CookieJar object)

setFileUpload(string $filename, string $formname, string $data = null, string $ctype = null) : \Zend_Http_Client

Set a file to upload (using a POST request)

Can be used in two ways:

$data is null (default): $filename is treated as the name if a local file which will be read and sent. Will try to guess the content type using mime_content_type().
$data is set - $filename is sent as the file name, but $data is sent as the file contents and no file is read from the file system. In this case, you need to manually set the Content-Type ($ctype) or it will default to application/octet-stream.

Parameters

Name	Type	Description
$filename	string	Name of file to upload, or name to save as
$formname	string	Name of form element to send as
$data	string	Data to send (if null, $filename is read and sent)
$ctype	string	Content type to use (if $data is set and $ctype is null, will be application/octet-stream)

Throws

Exception	Description
\Zend_Http_Client_Exception

setHeaders(string | array $name, mixed $value = null) : \Zend_Http_Client

Set one or more request headers

This function can be used in several ways to set the client's request headers: 1. By providing two parameters: $name as the header to set (e.g. 'Host') and $value as it's value (e.g. 'www.example.com'). 2. By providing a single header string as the only parameter e.g. 'Host: www.example.com' 3. By providing an array of headers as the first parameter e.g. array('host' => 'www.example.com', 'x-foo: bar'). In This case the function will call itself recursively for each array item.

Parameters

Name	Type	Description
$name	string \| array	Header name, full header string ('Header: value') or an array of headers
$value	mixed	Header value or null

Returns

Type	Description
\Zend_Http_Client

Throws

Exception	Description
\Zend_Http_Client_Exception
