Zend查看url函数问题

first I'd like to admit I didn't do enough searching about this mainly because I didn't know how to put it in words fit for the search. is it 'getting clean urls in zend' or 'ignore what comes after the action in zend' I really can't name it well, so deeply sorry for this. guide me for duplicates, I'll delete this at once :>

now, story goes like this:
let's say in pageproject/public/home I've got a link

<a href="<?php  
echo $this->url(array(
            'controller' => 'test',
            'action' => 'index'
        ));
        ?>
           ">
               <?php echo $this->translate('go_to_test_index'); ?>
</a>  

that would get me to project/public/home/test/index (index omitted by default)

let's say another link with parameter

<a href="<?php
        echo $this->url(array(
            'controller' => 'message',
            'action' => 'add',
            'id' => 1//some value or another parameter
        ));
        ?>
           ">
               <?php echo $this->translate('go_to_add_message'); ?>
</a>  

that would take me to project/public/home/message/add/1 till now I understand perfectly but the issue appears when I try to go back

<a href="<?php
        echo $this->url(array(
            'controller' => 'test',
            'action' => 'index'
        ));
        ?>
           ">
               <?php echo $this->translate('back'); ?>
</a>

as far as I know that should take me to project/public/home/test/index but instead I get project/public/home/test/index/id/1 (index not omitted) the test/index page is displayed but that id parameter is just wrong to be there

what is the proper name of this problem? what's causing it? am I missing some parameter of url? any pointers on how to fix it?

thanks a lot in advance

documentation referenced there Zend View Helpers

Use the reset option in the Url View Helper as shown below.

<a href="<?php
        echo $this->url(array(
            'controller' => 'test',
            'action' => 'index'
        ), null, true);
        ?>
           ">
               <?php echo $this->translate('back'); ?>
</a>

And here are few more tips for generating Urls.

1. Create a virtual host and point it to your projects public directory.
2. Use BaseUrl helper to generate absolute Urls.
3. Create routes and generate Urls using routes.

Hope this helps.

As @Jay Bhatt mentioned, there is a reset param which is defaulted to false.

Set it to true if you want to reset all current request params in the new generated link.

<a href="<?php 
    echo $this->url(
        array('controller' => 'test', 'action' => 'index'), 
        null, 
        true
    );
        ?>"><?php echo $this->translate('back'); ?></a>

Note that if you want to reset only one param, you can set it as null

<a href="<?php echo $this->url(array(
    'controller' => 'test', 'action' => 'index', 'id' => null
));
    ?>"><?php echo $this->translate('back'); ?></a>

Hope it helps
