My 1st post here! I am hopeful. Need help with file_get_contents and replacing

[EduardoEduardo]

I am looking to use file_get_contents to get a php file and replace each link ID with the

user ID so when they click the link it will be their user ID to unsubscribe.

$html = eval('?'.'>'.file_get_contents("$html",1).'<'.'?');
$html =  preg_replace('Content_To_Replace', "Content_Replacement", $html); //// this is not working

 

I am using the "eval" function to make the PHP code work. Not sure what this does but it works.

 

It's link 2 that I need help with. Thanks for your speedy reply on my first post here. =)
