Symbolic Link - Security Issue?

Hi, I have a directory with an index.php script so that the url is something along the lines of http://www.mydomain.com/search/ .. Now following the same logic I wanted to write another script but not bother creating another directory so I wrote my script called test.php and then created a symbolic link to it by pointing 'test' (without the quotes, of course) to test.php and upon going to http://www.mydomain.com/search/test I got my script's source displayed in plain text on the browser .. Now maybe this is something I shouldnt be doing or the way I have the webserver configured but, just thought Id find out, by checking to see if anyone else knows anything about this.. BTW, I am on a Redhat 8 Linux (kernel version 2.4.7-2) server running php version 4.0.6 and I have checked in the conf of Apache to see for the source its set to phps .. Thanks..
