使用PHP的XML RSS提要

Question

I'm using the following code to piece together a series of variables declared further back in the script to form the link portion of a RSS XML feed. I need to insert a ampersand between the variables to complete the URL properly. I've tried using & and also just & put it ends up with an error:

error on line 7 at column 194: Entity Ref: expecting ';'

Can somebody please show me so I can see what I am doing wrong?

echo '<link>' . $url . 'ampersand_goes_here' . $mlcall. '' . $title . '</link>';

Answer 1

try enclosing the string within the link tag with the htmlspecialchars() function.

echo '<link>' . htmlspecialchars($url . 'ampersand_goes_here' . $mlcall. '' . $title) . '</link>';
