Zend_Http_Client

Description

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)

setEncType (line 731)

Set the encoding type for POST data

access: public

Zend_Http_Client setEncType ([string $enctype = self::ENC_URLENCODED])

string $enctype

setFileUpload (line 698)

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.

throws: Zend_Http_Client_Exception
access: public

Zend_Http_Client setFileUpload (string $filename, string $formname, [string $data = null], [string $ctype = null])

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

setHeaders (line 386)

Set one or more request headers

This function can be used in several ways to set the client's request headers:

By providing two parameters: $name as the header to set (e.g. 'Host') and $value as it's value (e.g. 'www.example.com').
By providing a single header string as the only parameter e.g. 'Host: www.example.com'
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.

throws: Zend_Http_Client_Exception
access: public

Zend_Http_Client setHeaders (string|array $name, [mixed $value = null])

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

setMethod (line 350)

Set the next request's method

Validated the passed method and sets it. If we have files set for POST requests, and the new method is not POST, the files are silently dropped.

throws: Zend_Http_Client_Exception
access: public

Zend_Http_Client setMethod ([string $method = self::GET])

string $method

setParameterGet (line 455)

Set a GET parameter for the request. Wrapper around _setParameter

access: public

string $value

setParameterPost (line 474)

Set a POST parameter for the request. Wrapper around _setParameter

access: public

Zend_Http_Client setParameterPost (string|array $name, [string $value = null])

string|array $name
string $value

setRawData (line 752)

Set the raw (already encoded) POST data.

This function is here for two reasons:

For advanced user who would like to set their own data, already encoded
For backwards compatibilty: If someone uses the old post($data) method. this method will be used to set the encoded data.

$data can also be stream (such as file) from which the data will be read.

access: public

Zend_Http_Client setRawData (string|resource $data, [string $enctype = null])

string|resource $data
string $enctype

setStream (line 878)

Set the URI for the next request

throws: Zend_Http_Client_Exception
access: public

Zend_Http_Client setUri (Zend_Uri_Http|string $uri)

Zend_Uri_Http|string $uri

_detectFileMimeType (line 1314)

Attempt to detect the MIME type of a file using available extensions

This method will try to detect the MIME type of a file. If the fileinfo extension is available, it will be used. If not, the mime_magic extension which is deprected but is still available in many PHP setups will be tried.

If neither extension is available, the default application/octet-stream MIME type will be returned

return: MIME type
access: protected

string _detectFileMimeType (string $file)

string $file: File path

_getParametersRecursive (line 1264)

Helper method that gets a possibly multi-level parameters array (get or post) and flattens it.

The method returns an array of (key, value) pairs (because keys are not necessarily unique. If one of the parameters in as array, it will also add a [] suffix to the key.

This method is deprecated since Zend Framework 1.9 in favour of self::_flattenParametersArray() and will be dropped in 2.0

deprecated: since 1.9
access: protected

array _getParametersRecursive (array $parray, [bool $urlencode = false])

array $parray: The parameters array
bool $urlencode: Whether to urlencode the name and value

_prepareHeaders (line 1076)

Prepare the request headers

access: protected

array _prepareHeaders ()

_setParameter (line 494)
