Links on RSS

I’m still trying to generate my RSS, and it is starting to shape up.
However I can’t generate a link, only text.

IF I put

echo "<title>".$my_title[$counter]. ". . . id_art = " .$my_id_art[$counter]."</title>";

I get an output of my title, followed by the id_art number/

If I put

$my_link= "<a href= \\"actualites-pharmaceutiques.php?id_art=".   $my_id_art[$counter] . "\\">   " . $my_title[$counter] . "</a>";

echo "<title>". $my_link ."</title>";

I get a blank page.

Is something wrong with my syntax ?

$my_id_art[$counter] contains the number of the article in the data base
$my_title[$counter] contains the text I want to show/

for ( $counter = 0 ; $counter < $i ; $counter += 1) {
			
$my_link= "<a href= \\"actualites-pharmaceutiques.php?id_art=". $my_id_art[$counter] . "\\">   " . $my_title[$counter] . "</a>";

				echo "<item>";
		   		echo "<title>".$my_title[$counter]. ". . . id_art = " .$my_id_art[$counter]."</title>";
				//echo "<title>".$my_title[$counter]. $my_link ."</title>";
				
				//echo "<title>"."title"."</title>";
		   		//echo "<link>http://www.gimra.com/evenements.php?id_art=".$my_id_art[$counter]."</link>";
				//echo "<description>"."description messages "."</description>";
	   			echo "<pubDate>".$my_date[$counter]."</pubDate>";
				echo "</item>";
		};

echo "<description><![CDATA[" . ($my_link) . "]]></description>";

PERFECT, that works, Thank you
