may i disable the title link in one node where i will execute a php code ???

You don't say what you're trying to do, but I'm going to guess that putting php code in the node is the wrong way to do it. As far as I'm concerned every node should have a title. If you're trying to run code on a specific page, consider putting it in a block, or in your theme's template.php, or writing a module. --Andrew
