如何从PHP中的变量打印HTML代码？

Question

I am developing a PHP site, and have encountered the following problem. I have this line of code:

<div id="buynow"><?php echo $buynow; ?></div>

The variable $buynow has an html code (a paypal buy now button), and I would like to print/echo the html code that it gets processed.

With the current code, it prints the html code itself, not the desired result.

Thanks in advance

String:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="XXXXXXXXXXXX">
<table>
<tr><td><input type="hidden" name="on0" value="Colors">Colors</td></tr><tr><td><select name="os0">
    <option value="Black">Black </option>
    <option value="White">White </option>
</select> </td></tr>
</table>
<input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_buynowCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
<img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>

Note: The value is replaced to XXXXXXXXX on purpose, in the code it is the original.

Answer 1

maybe try this:

<div id="buynow"><?php echo htmlspecialchars_decode($buynow); ?></div>

or use

<div id="buynow"><?php echo html_entity_decode($buynow); ?></div>
