The easiest way to do that would be to use the Params plugin  introduced in beta5  It has utility methods to make it easy to access different types of parameters  As always  reading the tests can prove valuable to understand how something is supposed to be used  Get a single value To get the value of a named parameter in a controller  you will need to select the appropriate method for the type of parameter you are looking for and pass in the name  Examples   this- gt params  - gt fromPost  paramname         From POST  this- gt params  - gt fromQuery  paramname        From GET  this- gt params  - gt fromRoute  paramname        From RouteMatch  this- gt params  - gt fromHeader  paramname       From header  this- gt params  - gt fromFiles  paramname        From file being uploaded     Default values All of these methods also support default values that will be returned if no parameter with the given name is found  Example   orderBy    this- gt params  - gt fromQuery  orderby    name     When visiting http   example com  orderby birthdate   orderBy will have the value birthdate  When visiting http   example com    orderBy will have the default value name     Get all parameters To get all parameters of one type  just don t pass in anything and the Params plugin will return an array of values with their names as keys  Example   allGetValues    this- gt params  - gt fromQuery       empty method call  When visiting http   example com  orderby birthdate amp filter hasphone  allGetValues will be an array like array       orderby    gt   birthdate        filter     gt   hasphone          Not using Params plugin If you check the source code for the Params plugin  you will see that it s just a thin wrapper around other controllers to allow for more consistent parameter retrieval  If you for some reason want need to access them directly  you can see in the source code how it s done  Example   this- gt getRequest  - gt getRequest  name    default     this- gt getEvent  - gt getRouteMatch  - gt getParam  name    default     NOTE  You could have used the superglobals   GET    POST etc   but that is discouraged

The easisest way to get a posted json string  for example  is to read the contents of  php   input  and then decode it  For example i had a simple Zend route    save-json    gt  array   type    gt   Zend Mvc Router Http Segment                options    gt  array                   route       gt    save-json                     defaults    gt  array                       controller    gt   CDB Controller Index                        action        gt   save-json                                                  and i wanted to post data to it using Angular s  http post  The post was fine but the retrive method in Zend    this- gt params  - gt fromPost  paramname       didn t get anything in this case  So my solution was  after trying all kinds of methods like   POST and the other methods stated above  to read from  php        content   file get contents  php   input    print r json decode  content      I got my json array in the end   Hope this helps

All the above methods will work fine if your content-type is  application -www-form-urlencoded   But if your content-type is  application json  then you will have to do the following    params   json decode file get contents  php   input    true   print r  params    Reason   See  7 in https   www toptal com php 10-most-common-mistakes-php-programmers-make
