How to add PHP variables to a href url

Question

Im trying to add a PHP variable to a href url

This is the code:

PHP

$uid= $_SESSION['userid'];

HTML

<a href=http://example.com/uid= <?php echo ".$uid."?> /a>

How do you add, when I do it, this is what it redirect too: http://example.com/uid=.

Make sure you have session_start() at the top of your script, and the syntax should look like <a href="http://example.com/uid=<?php echo $uid; ?>">...</a> — user3141031

Your syntax is broken. You want to get rid of the quotes inside the PHP part (but wrap the entire href attribute in them) — Pekka

This depends ENTIRELY on how you're using that html. Is it being assigned to a php string? Then echo is the totally wrong tool. Is it direct output "out" of php mode? Then it'd work, if you fixed your html syntax. — Marc B

@user3245415 you're supposed to pick the answer that helps you most at some point. Are you still stuck on this? — Paul Gregory

Try this,

<?php
@session_start();
$uid= $_SESSION['userid'];
?>
<a href="http://example.com/?uid=<?php echo $uid; ?>" >Your link text</a>

Perhaps something like this:

print '<a href=http://example.com/?uid=' . $uid . '>Link</a>';

Syntax is wrong - missing closing bracket for a tag and the double-quote isn't needed.

try this

<?php 
$url = 'https://www.w3schools.com/php/';
?>

<a href="<?php echo $url;?>">PHP 5 Tutorial</a>

Or for PHP 5.4+ (<?= is the PHP short echo tag):
<a href="<?= $url ?>">PHP 5 Tutorial</a>

or 
echo '<a href="' . $url . '">PHP 5 Tutorial</a>';

This is one of the most helpful

echo "<td>".($tripId != null ? "<a target=\"_blank\"href=\"http://www.rooms.com/r/trip/".$tripId."\">".$tripId."</a>" : "-")."</td>";

It will work!

You're doing a couple things wrong.

In HTML you should quote attribute values such as href
In PHP you're not concatenating anything, just echoing
You forgot the link text
For readability, you can (probably) use the <?= shorthand instead of <?php echo
<a /a> is broken tag syntax. Should be <a>...</a>

End result is this:

<a href="http://example.com/uid=<?=$uid?>">Link Text</a>
