Editing core files is not a right approach so you have to create a custom module for it. Once the module created and these are the steps which you have to follow:
Create default.xml (Layout File) in app/code/Magenticians/Mymodule/view/frontend/layout and add this code under it:
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="header.links">
<block class="Magenticians\Mymodule\Block\Link" name="custom-header-link">
<arguments>
<argument name="label" xsi:type="string" translate="true">Login</argument>
<argument name="path" xsi:type="string" translate="true">customer/account/login</argument>
</arguments>
</block>
</referenceBlock>
</body>
</page>
You can see that I have set the label as Login and Path to the store's login page.
Create Link.php (Block File) in app/code/Magenticians/Mymodule/Block and add this code under it:
<?php
namespace Magenticians\Mymodule\Block;
class Link extends \Magento\Framework\View\Element\Html\Link
{
/**
* Render block HTML.
*
* @return string
*/
protected function _toHtml()
{
if (false != $this->getTemplate())
{
return parent::_toHtml();
}
return '<li><a ' . $this->getLinkAttributes() . ' >' . $this->escapeHtml($this->getLabel()) . '</a></li>';
}
}At last, just run the following CLI commands in the root directory of your store:
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento cache:clean
php bin/magento cache:flush
