Built PHP from source with custom DataDirect ODBC drivers, but can't auto start with systemd

I was able to resolve my issue by adding the following lines to my /usr/lib/systemd/system/httpd.service file, under the [Service] section:

Environment="ODBCINST=/opt/Progress/DataDirect/Hybrid_Data_Pipeline_for_ODBC/odbcinst.ini" Environment="ODBC_HOME=/opt/Progress/DataDirect/Hybrid_Data_Pipeline_for_ODBC" Environment="ODBCINI=/opt/Progress/DataDirect/Hybrid_Data_Pipeline_for_ODBC/odbc.ini" Environment="TZ=America/Los_Angeles"
