<?php 
$Amazon = get_post_meta($post->ID, "Lien Amazon", true);
?>
<?php   
    if( $Amazon != NULL ){ 
        echo '<li><span class="post-meta-key"><a href=". $Amazon . ">Acheter sur Amazon</a></li>' ;} 
    else {
        echo '<li><span class="post-meta-key"><a href="https://www.amazon.fr/bd/b?ie=UTF8&node=301133">Acheter sur Amazon</a></li>' ;}

What has the title to do with the question? What is the problem? — Rizier123, May 15 '16 at 15:15
Your amazon link can't work as you miss two single quotes around your concat. But this code can never generate an infinite loop - there is not even a regular one — clemens321, May 15 '16 at 15:17

Here is an output error. You haven't closed and reopened the string on trying to concat a variable.

echo '<li><span class="post-meta-key"><a href=". $Amazon . ">Acheter sur Amazon</a></li>' ;

Do instead:

echo '<li><span class="post-meta-key"><a href="'. $Amazon . '">Acheter sur Amazon</a></li>' ;

Infinite loop. Why?
