PHP在回显HTML时打印HTML符号

Question

How can I use HTML symbols when printing HTML with PHP?

For example:

<?php
   echo "<p>here is a symbol &bull;</p>";
?>

The • is an HTML symbol for bullet: http://www.w3schools.com/tags/ref_symbols.asp.

I currently see "here is a symbol &bull". I expect to see "here is a symbol •".

Your code doesn't look like it has problems at all. But there are a few things you can do:

• Copy the bullet point symbol from somewhere else, and directly paste it in your code (not recommended)
• Check the source code of your page, and see what you get. If you have &bull, then you know you've got an error. Try rendering using single quotes or print <<<HERE HERE;.
• Check if your code really is exactly that. Any subtle changes might make a difference.
