how to create a link using php ?

Creating a link with PHP uses the same code as it dose in HTML. Depending on where we are getting our information, and where in our file it is we might present this HTML in a slightly different way.
If you are making a link in a PHP document, that is outside of the PHP brackets, you just use HTML. Here is an example:
a href=https://twitter.com/angela_bradley My Twitter a


If the link needs to be inside of the PHP you have two options. Option one is to end the PHP and then reopen it. Here is an example:

a href="https://twitter.com/angela_bradley"My Twitter a


The other option is to print or echo the HTML code inside of the PHP. Here is an example:
My Twitter"
?>

Another thing we can do is create a link from a variable. Let's say that the variable $url holds the URL for a website that someone has submitted, or that we have pulled from a database. We can use the variable in our HTML.
a href=https://twitter.com/angela_bradley My Twitter a
$site_title a"
?>
