I am in the process of creating a website using php and due to hosting my website locally and then uploading it onto a server I want an easy way of changing the root domain without manually changing it in every single place I have a domain, so I proposed storing the root domain as a variable. n.b. I have simplified down the names of the files.
I created a a variable called $rootDomain
<?php $rootDomain = "http://localhost/testWebsite/"; ?>
Next I have a new page in a sub folder called: page.php. I get to this page via a link in a header that is used for all the pages.
<a href=<?php $rootDomain?>"pageone/page.php"><li><?php echo$firstLink?></li>
Using the generic header I have on all pages I want to get back to the main index page. The link used looks like this:
<a href=<?php $rootDomain?>"index.php"><?php echo$websiteName?></a>
The expected link location should send me to:
But the link it is displaying is:
Which is an error.
When I have tested it using the link directly without the variable :
<a href="http://localhost/index.php"><?php echo$websiteName?></a>
There is no error and I get the expected outcome.
I am struggling to work out what I am doing wrong and any help would be much appreciated.
