How to put variable value in a href?

Question

This question may sound banal, but I'm really new to php. I have:

<?php $kzl="pencho"; ?>

<a href="settings.php?var=$kzl">asdf</a>

in the script settings.php

<? echo &_GET['var']; ?>

and on the screen is printed kzl not the value in kzl, why ?

Answer 1

You need to print value of $kzl in url. Use this;

<a href="settings.php?var=<?php echo $kzl;?>">asdf</a>

Or you can use;

echo '<a href="settings.php?var=' . $kzl . '">asdf</a>';
