A golden rule is do not set environment variables like LD_LIBRARY_PATH or ORACLE_HOME in PHP scripts. These variables need to be set in the environment that starts the webserver. This may or may not be your problem - not enough supporting or investigative information is given for me to guess. Please follow up in a Support forum (e.g. the php-db mail list, or Oracle's OTN forum) before reopening this bug.

FYI, environment variables are already in the Apache users env. variables list.
