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)

Set a file to upload (using a POST request)

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

Can be used in two ways:

  1. $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().
  2. $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

$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)

Exceptions

\Zend_Http_Client_Exception

Returns

\Zend_Http_Client

Set one or more request headers

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

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

stringarray

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

$value

mixed

Header value or null

Exceptions

\Zend_Http_Client_Exception

Returns

\Zend_Http_Client

Set the next request's method

setMethod(string $method = self::GET) : \Zend_Http_Client

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.

Parameters

$method

string

Exceptions

\Zend_Http_Client_Exception

Returns

\Zend_Http_Client

Set a GET parameter for the request. Wrapper around _setParameter

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

Parameters

$name

stringarray

$value

string

Returns

\Zend_Http_Client

Set a POST parameter for the request. Wrapper around _setParameter

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

Parameters

$name

stringarray

$value

string

Returns

\Zend_Http_Client

Set the raw (already encoded) POST data.

setRawData(string|resource $data, string $enctype = null) : \Zend_Http_Client

This function is here for two reasons:

  1. For advanced user who would like to set their own data, already encoded
  2. 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.

Parameters

$data

stringresource

$enctype

string

Returns

\Zend_Http_Client

Set streaming for received data

setStream(string|boolean $streamfile = true) : \Zend_Http_Client

Parameters

$streamfile

stringboolean

Stream file, true for temp file, false/null for no streaming

Returns

\Zend_Http_Client

Set the unmask feature for GET parameters as array

setUnmaskStatus(boolean $status = true) : \Zend_Http_Client

Example: foo%5B0%5D=a&foo%5B1%5D=b becomes foo=a&foo=b

This is usefull for some services

Parameters

$status

boolean

Returns

\Zend_Http_Client

Set the URI for the next request

setUri(\Zend_Uri_Http|string $uri) : \Zend_Http_Client

Parameters

$uri

\Zend_Uri_Httpstring

Exceptions

\Zend_Http_Client_Exception

Returns

\Zend_Http_Client

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

_detectFileMimeType(string $file) : string

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

Parameters

$file

string

File path

Returns

stringMIME type

Convert an array of parameters into a flat array of (key, value) pairs

_flattenParametersArray(array $parray, string $prefix = null) : array
Static

Will flatten a potentially multi-dimentional array of parameters (such as POST parameters) into a flat array of (key, value) paris. In case of multi-dimentional arrays, square brackets ([]) will be added to the key to indicate an array.

since 1.9

Parameters

$parray

array

$prefix

string

Returns

array

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

_getParametersRecursive(array $parray, boolean $urlencode = false) : array

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
