Description:
------------
extension=php_oci8.dll
extension=php_oracle.dll

All oci8 functions seem to work even without defining the oracle env. variables(ORACLE_HOME,ORACLE_SID,TNS_ADMIN...etc..), database connection, update and table query and display,..no problem, but the browser keeps on spinning even on ldap functions not using oracle which already been running smoothly. 
When I tried disabling the oci8, spinning stops but my oci8 functions won't work.

I tried defining the ora env. variables(below) at the start of my PHP script but still got the browser spinning.

 PutEnv("ORACLE_SID=PROD");
 PutEnv("ORACLE_HOME=C:\Progra~1\oracle\ora81");
 PutEnv("TNS_ADMIN=C:\Progra~1\oracle\ora81\network\admin");
 PutEnv("LD_LIBRARY_PATH=C:\Progra~1\oracle\ora81\lib");
 PutEnv("NLS_LANG=English_America.WE8ISO8859P1");
 PutEnv("ORA_NLS33=C:\Progra~1\oracle\ora8  
        \common\nls\admin\data");  

Am I missing something with the configuration of PHP on windows using oracle database?
Any other environment variables that needs to be setup?

Thanks in advance for your help. : )
