I installed Oracle Instant Client 12.1 (32bit) and PHP OCI8 on SalixOS 14.1 XFCE 32bit. ORACLE_HOME and other variables are set. Only LD_LIBRARY_PATH in apache variables has other (some default) value

I did set it in "/etc/profile" and in "/etc/ld.so.conf". All not works

Well connection to the oracle server works in php script running like command line. But not from apache (web browser) like web app. Can you write me, please, where to set it?
Final LD_LIBRARY_PATH must contains string "/usr/lib/oracle/12.1/client/lib".
