Two things:

1.  Unless you used the --prefix option with configure, freetds.conf is
normally at /usr/local/etc/freetds.conf.

2.  When using PHP with a webserver, make sure the webserver has
permissions to read freetds.conf.  Normally the "nobody" account owns
httpd; it has almost no privileges.  

I don't use PHP.  Perhaps you can put something like 

<?php 
$file = file_get_contents ('/usr/local/etc/freetds.conf'); 
Echo $file;
?>

in your script to make sure you have the right location and the file is
readable to your process?

HTH.
