Description:
------------
For some strange reason, php is not correctly passing the info on some key oracle env vars (TNS_ADMIN) to the oci8 lib.

getenv() is able to catch the value, but ocilogon not.

The cli version works ok (with standard ENV vars)



Reproduce code:
---------------
I have in my httpd.conf:

setenv ORACLE_HOME /var/oracle/product/8.1.7
setenv TNS_ADMIN /var/oracle/product/8.1.7/network/admin

Script 1:

<?
$tns=getenv('TNS_ADMIN');
echo "$tns<p>";
$conn = ocilogon('publicac',cdnp1m,'wdb2');
?>

returns:

/var/oracle/product/8.1.7/network/admin
Warning: ocilogon(): _oci_open_server: Error while trying to retrieve text for error ORA-12154 in /web/webboe/kk.php on line 4

Script 2:

<?
putenv("TNS_ADMIN=/var/oracle/product/8.1.7/network/admin");

$tns=getenv('TNS_ADMIN');
echo "$tns<p>";

$conn = ocilogon('publicac',cdnp1m,'wdb2');
?>

returns:

/var/oracle/product/8.1.7/network/admin

and connects OK to the oracle database.
