Zend route with unlimited parameters - php

Question

I am using Zend 1.10. I am trying to create a route for unlimited variables like abc.com/var1/var2/var3 and so on.
Till now i have searched and find out that i can add route for each variable like
$route = new Zend_Controller_Router_Route(
'/emaillog/:var1',
array(
'controller' => 'emaillog', // The controller to point to.
'action' => 'index', // The action to point to, in said Controller.
':var1' =>null //default value if param is not passed
)
);
$frontController->getRouter()->addRoute('emaillogWithVar1', $route);
and for second variable,
$route = new Zend_Controller_Router_Route(
'/emaillog/:var1/:var2',
array(
'controller' => 'emaillog', // The controller to point to.
'action' => 'index', // The action to point to, in said Controller.
':var1' =>null, //default value if param is not passed
':var2' =>null //default value if param is not passed
)
);
$frontController->getRouter()->addRoute('emaillogWithVar2', $route);
But the work i going to do, can contain 1-∞ infinite variables.
So i want to have once route for unlimited variables.
Any help will be appreciated!

Answer 1

There is a way to get infinite params. For that you don't have to declare them.
Lest say the url is index/test/p1/p2/p3/p4/p5, now if you try the following inside IndexController:
public function testAction()
{
var_dump($this->getRequest());
}
You will get a dump of an instance of Zend_Controller_Request_Http, in that dump, you will see, 2 properties, _params & _pathInfo, Like:
protected '_pathInfo' => string '/index/test/p1/p2/p3/p4/p5' (length=26)
protected '_params' =>
array (size=5)
'controller' => string 'index' (length=5)
'action' => string 'test' (length=4)
'p1' => string 'p2' (length=2)
'p3' => string 'p4' (length=2)
'module' => string 'default' (length=7)
1st method: Now in _params, they will occur as key => value pairs, as long as they are even, the last odd param will be ignored. You can get these by(for example):
$params = $this->getRequest()->getParams();
unset($params['controller']);
unset($params['action']);
unset($params['module']);
$params = array_merge(array_keys($params), array_values($params));
var_dump($params);
Output:
array (size=4)
0 => string 'p1' (length=2)
1 => string 'p3' (length=2)
2 => string 'p2' (length=2)
3 => string 'p4' (length=2)
2nd Method: OR you can use _pathinfo to get the params using explode, like:
$path = $this->getRequest()->getPathinfo();
$params = explode('/', $path);
unset($params[0]);
unset($params[1]);
unset($params[2]);
var_dump($params);
Output:
array (size=5)
3 => string 'p1' (length=2)
4 => string 'p2' (length=2)
5 => string 'p3' (length=2)
6 => string 'p4' (length=2)
7 => string 'p5' (length=2)
