Phalcon Request Environment

HTTP request is originated by browser which contains additional information regarding the request such as header data, files, variables, etc. A web based application needs to parse that information so as to provide the correct response back to the requester. All the information of request is stored under directory Phalcon\Http\Request.

Retrieving Values

To retrieve value PHP automatically decides the array type as $_GET and $_POST depending on type of request.

Phalcon\Http\Request allows us to access the values stored in the $_REQUEST, $_GET and $_POST arrays and filter them with the filter service i.e. Phalcon\Filter.

Following is the example of same behavior:

<?php

use Phalcon\Filter;

$filter = new Filter();

// Automatically applying the filter
$email = $request->getPost('user_email', 'email');

// Setting a default value if the param is null
$email = $request->getPost('user_email', 'email', 'some@example.com');

// Setting a default value if the param is null without filtering
$email = $request->getPost('user_email', null, 'some@example.com');
