The Request Class

Laminas\Http\Request is responsible for providing a fluent API that allows a developer to interact with all the various parts of an HTTP request.

A typical HTTP request looks like this:

| METHOD | URI | VERSION |
|        HEADERS         |
|         BODY           |

In simplified terms, the request consists of a method, URI, and HTTP version number; together, they make up the "Request Line." This line is followed by zero or more HTTP headers, which is followed by an empty line and then the request body; the body is typically used when a client wishes to send data — which could be urlencoded parameters, a JSON document, an XML document, or even one or more files — to the server. More information on the structure and specification of a HTTP request can be found in RFC-2616 on the W3.org site.

Quick Start

Request objects can either be created from the provided fromString() factory, or, if you wish to have a completely empty object to start with, by manually instantiating the Laminas\Http\Request class with no parameters.

use Laminas\Http\Request;

$request = Request::fromString(<<<EOS
POST /foo HTTP/1.1
HeaderField1: header-field-value1
HeaderField2: header-field-value2

foo=bar
EOS
);

// OR, the completely equivalent

$request = new Request();
$request->setMethod(Request::METHOD_POST);
$request->setUri('/foo');
$request->getHeaders()->addHeaders([
    'HeaderField1' => 'header-field-value1',
    'HeaderField2' => 'header-field-value2',
]);
$request->getPost()->set('foo', 'bar');

Available Methods

The following table details available methods, their signatures, and a brief description. Note that the following references refer to the following fully qualified class names and/or namespaces:

  • HeaderInterface: Laminas\Http\Header\HeaderInterface
  • Headers: Laminas\Http\Headers
  • Header: Laminas\Http\Header
  • Parameters: Laminas\Stdlib\ParametersInterface
  • Request: Laminas\Http\Request
  • Uri: Laminas\Uri\Http
Method signature Description
static fromString(string $string) : Request A factory that produces a Request object from a well-formed HTTP request message string.
setMethod(string $method) : self Set the method for this request.
getMethod() : string Return the method for this request.
setUri(string|Uri $uri) : self Set the URI/URL for this request; this can be a string or an instance of Laminas\Uri\Http.
getUri() : Uri Return the URI for this request object.
getUriString() : string Return the URI for this request object as a string.
setVersion(string $version) : self Set the HTTP version for this object, one of 1.0, 1.1 or 2 (Request::VERSION_10, Request::VERSION_11, Request::VERSION_2). HTTP/2 support was added in laminas-http 2.10.0.
getVersion() : string Return the HTTP version for this request.
setQuery(Parameters $query) : self Provide an alternate Parameter Container implementation for query parameters in this object. (This is NOT the primary API for value setting; for that, see getQuery()).
getQuery(string|null $name, mixed|null $default) : null|string|Parameters Return the parameter container responsible for query parameters or a single query parameter based on $name.
setPost(Parameters $post) : self Provide an alternate Parameter Container implementation for POST parameters in this object. (This is NOT the primary API for value setting; for that, see getPost()).
getPost(string|null $name, mixed|null $default) : null|string|Parameters Return the parameter container responsible for POST parameters or a single POST parameter, based on $name.
getCookie() : Header\Cookie Return the Cookie header, this is the same as calling $request->getHeaders()->get('Cookie');.
setFiles(Parameters $files) : self Provide an alternate Parameter Container implementation for file parameters in this object, (This is NOT the primary API for value setting; for that, see getFiles()).
getFiles(string|null $name, mixed|null $default) : null|string|Parameters Return the parameter container responsible for file parameters or a single file parameter, based on $name.
setHeaders(Headers $headers) : self Provide an alternate Parameter Container implementation for headers in this object, (this is NOT the primary API for value setting, for that see getHeaders()).
getHeaders(string|null $name, mixed|null $default) : mixed Return the container responsible for storing HTTP headers. This container exposes the primary API for manipulating headers set in the HTTP request. See the section on Headers for more information. Return value is based on $name; null returns Headers, while a matched header returns a Header\HeaderInterface implementation for single-value headers or an ArrayIterator for multi-value headers.
setMetadata(string|int|array|Traversable $spec, mixed $value) : self Set message metadata. Non-destructive setting of message metadata; always adds to the metadata, never overwrites the entire metadata container.
getMetadata(null|string|int $key, null|mixed $default) : mixed Retrieve all metadata or a single metadatum as specified by key.
setContent(mixed $value) : self Set request body (content).
getContent() : mixed Get request body (content).
isOptions() : bool Is this an OPTIONS method request?
isGet() : bool Is this a GET method request?
isHead() : bool Is this a HEAD method request?
isPost() : bool Is this a POST method request?
isPut() : bool Is this a PUT method request?
isDelete() : bool Is this a DELETE method request?
isTrace() : bool Is this a TRACE method request?
isConnect() : bool Is this a CONNECT method request?
isPatch() : bool Is this a PATCH method request?
isXmlHttpRequest() : bool Is this a Javascript XMLHttpRequest?
isFlashRequest() : bool Is this a Flash request?
renderRequestLine() : string Return the formatted request line (first line) for this HTTP request.
toString() : string Returns string
__toString() : string Allow PHP casting of this object.

Examples

Generating a Request object from a string

use Laminas\Http\Request;

$string = "GET /foo HTTP/1.1\r\n\r\nSome Content";
$request = Request::fromString($string);

$request->getMethod();    // returns Request::METHOD_GET
$request->getUri();       // returns Laminas\Uri\Http object
$request->getUriString(); // returns '/foo'
$request->getVersion();   // returns Request::VERSION_11 or '1.1'
$request->getContent();   // returns 'Some Content'

Retrieving and setting headers

use Laminas\Http\Request;
use Laminas\Http\Header\Cookie;

$request = new Request();
$request->getHeaders()->get('Content-Type'); // return content type
$request->getHeaders()->addHeader(new Cookie(['foo' => 'bar']));
foreach ($request->getHeaders() as $header) {
    printf("%s with value %s\n", $header->getFieldName(), $header->getFieldValue());
}

Retrieving and setting GET and POST values

use Laminas\Http\Request;

$request = new Request();

// getPost() and getQuery() both return, by default, a Parameters object, which
// extends ArrayObject
$request->getPost()->foo = 'Foo value';
$request->getQuery()->bar = 'Bar value';
$request->getPost('foo'); // returns 'Foo value'
$request->getQuery()->offsetGet('bar'); // returns 'Bar value'

Generating a formatted HTTP Request from a Request object

use Laminas\Http\Request;

$request = new Request();
$request->setMethod(Request::METHOD_POST);
$request->setUri('/foo');
$request->getHeaders()->addHeaders([
    'HeaderField1' => 'header-field-value1',
    'HeaderField2' => 'header-field-value2',
]);
$request->getPost()->set('foo', 'bar');
$request->setContent($request->getPost()->toString());
echo $request->toString();

/** Will produce:
POST /foo HTTP/1.1
HeaderField1: header-field-value1
HeaderField2: header-field-value2

foo=bar
*/
