I have the following script:

#!/usr/local/bin/php
<?
$handle=sybase_connect('SEVER', 'user', 'passwd');
sybase_select_db('test_db');
$result=sybase_query("select * from state");
print "<table>";
while($row=sybase_fetch_array($result)) 
 {
  print "<tr><td>";
  print $row[0];
  print "</td></tr>";
  print "</table>\n";
 }
?>

When I run this script from my shell, and I have 
$SYBASE=/right/dir in my environment, script run 
successfull.
When I run script from Apache (1.3.4), I get 
--------
connect: Can't assign requested address   
DB-Library: Login incorrect.              
--------

If I try to set up string "sybase.interface_file="/right/dir" in php.ini file,
I have failed run script both from Apache and from my shell.

Question: How php determine location interfaces file?
From user environment variable? I guess it right, becouse if I chenge somithing in /right/dir/interfaces file, i see it during script execution. And how I can to set up this location for runing from nobody:nobody (Apache)? In php-manual I can not find about "sybase.interface_file" in php.ini.

Thank you.
