I have a feeling that I am going to feel silly when it is explained, but can someone let me know what the following statement does?
href='<?= $authUrl ?>'
It is taken from the Google API Authentication login code below.
<div class="box">
<?php if (isset($authUrl)): ?>
<div class="request">
<a class='login' href='<?= $authUrl ?>'>Connect Me!</a>
</div>
<?php elseif($_SERVER['REQUEST_METHOD'] == 'POST'): ?>
<div class="shortened">
<p>Your call was successful! Check your drive for the following files: </p>
</div>
<?php else: ?>
<form method="POST">
<input type="submit" value="Click here to list your tables" />
</form>
<?php endif ?>
</div>
