htmlspecialchars在href中不起作用

Question

The following code is giving me a blank url, instead of a url that I have defined in my code.

Here is my code:

<a href="<?php echo htmlspecialchars($url); ?> ">
<?php echo htmlspecialchars("<Click> visit to know more");?>
</a>

Answer 1

Try this

<?php $url = 'http://www.facebook.com/nokia?ref=stream&hc_location=stream'; ?>

<a href="<?php echo htmlspecialchars($url); ?> ">
    <?php echo htmlspecialchars("<Click> visit to know more");?>
</a>
