Question

I want to pass some value in phtml file to another phtml file somewhere else

as an example 1.phtml file like below

<?php
$inputMessage = 'Hello World';
Mage::getSingleton('core/session')->setWelcomeMessage($inputMessage);
?>

and 2.phtml file like below

<?php
$outputMessage = Mage::getSingleton('core/session')->getWelcomeMessage();
echo $this->__($outputMessage);
?>

You need to write block in your custom module.

Path: Vendor/Module/Block/Customer/Links.php

<?php

namespace Vendor\Module\Block\Customer;

use Magento\Framework\ObjectManagerInterface;

class Links extends \Magento\Framework\View\Element\Template
{
    /**
     *
     * @var \Magento\Customer\Model\Session
     */
    protected $_customerSession;

    /**
     * @param \Magento\Framework\View\Element\Template\Context $context
     * @param \Magento\Customer\Model\Session $customerSession
     */
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Customer\Model\Session $customerSession
    ) {
        $this->_customerSession = $customerSession;
        parent::__construct($context);
    }

    /**
     * Check customer is logged in or not
     *
     * @return boolean
     */
    public function isLoggedIn()
    {
        return $this->_customerSession->isLoggedIn();
    }

    /**
     * Check customer is logged in or not
     *
     * @return boolean
     */
    public function getCustomerName()
    {
        return $this->_customerSession->getCustomer()->getName();
    }
}

Your Vendor\Module/view/frontend/templates/Customer/links.phtml

<?php if($block->isLoggedIn()): ?>
    <li>
        <div>
            <a href="<?= $this->getUrl('customer/account/logout'); ?>" class="action primary"><?= __('logout'); ?></a>
        </div>
        <div><?= __('Hi, %1', $block->getCustomerName()); ?><a href="<?= $this->getUrl('customer/account/edit'); ?>"><?= __('Edit'); ?></a></div>
    </li>
<?php endif; ?>

Please accept as answer if it helped you. It will help others too. — P_U, Mar 06 '18 at 06:14
so cant i pass value module to module because in your case its passing value same module block to view — HemalHerath, Mar 06 '18 at 06:38
You can write same block code in helper file and can call helper file in any module's template. — P_U, Mar 06 '18 at 06:51
