Answer 1

You can call your phtml file in another phtml file as below

<?php echo $this->getLayout()->createBlock('core/template')->setTemplate('module-folder-name/show.phtml')->toHtml() ?> 

But if you want to show your phtml file from controller as you commented below my answer, you can call it as below.

Create a phtml file

app/design/frontend/your/theme/template/module/show.phtml

<?php
 $model=Mage::getModel('entry/entry')->getCollection()->getData();
 echo "<pre>";
 print_r($model);
 exit();

 ?>

Create an xml file

app/design/frontend/your/theme/layout/module.xml

<?xml version="1.0"?>   
<layout version="0.1.0">   
  <module_index_index>   
    <reference name="root">   
      <action method="setTemplate"><template>page/1column.phtml</template></action>   
    </reference>   
    <reference name="content">   
      <block type="module/index" name="module_index" template="module/show.phtml"/>   
    </reference>   
  </module_index_index>   
</layout>   

Create a controller file

app/code/local/Vendor/Module/controllers/IndexController.php

<?php
class Vendor_Module_IndexController extends Mage_Core_Controller_Front_Action{
    public function IndexAction() {

    $this->loadLayout();   
    $this->renderLayout(); 

    }
}

Answer 2

Place the bellow code where you want to call your file:

<?php echo $this->getLayout()->createBlock('core/template')->setTemplate('path/to/show.phtml')->toHtml() ?> 

Answer 3

To call .phtml file through controller:

try this code--

public function showAction()
    {


    $block = $this->getLayout()->createBlock('core/template');

    // Assign your template to it
    // This path is relative to your current theme (eg: rwd/default/template/...)
    $block->setTemplate('entry/show.phtml');

    // Render the template to the browser
    echo $block->toHtml();
  }

}

in your main template(.phtml file) write this code:

<a href="<?php echo $this->geturl("entry/index/show"); ?>">Show</a>
