Install php oci8 on OSX

how to install oci8 for php:

refer to:

http://www.oracle.com/technology/pub/notes/technote_php_instant.html

what not mention in the documtation is :::

after finished installation and i want to  use cli, I must define

the DYLIB_LIBRARY_PATH in my .bash_profile OR /etc/profiles if i want

ex: 

export DYLIB_LIBRARY_PATH=/usr/lib/oracle/10.2/lib:$DYLIB_LIBRARY_PATH       the instantclient library downloaded

this also goes to Linux installation but the export variable is different

for linux(s):

export LIBRARY_PATH=/path/to/instantclientlib:${LIBRARY_PATH}
