    If you're using PHP with Oracle Instant Client, you can use easy connect
    naming method described here:
    <A
HREF="http://download-west.oracle.com/docs/cd/B12037_01/network.101/b10775/naming.htm#i498306"
TARGET="_top"
>http://download-west.oracle.com/docs/cd/B12037_01/network.101/b10775/naming.htm#i498306</A
>.
    Basically this means you can specify "//db_host[:port]/database_name"
    as database name. But if you want to use the old way of naming you
    <SPAN
CLASS="emphasis"
><I
CLASS="emphasis"
>must</I
></SPAN
> set either <TT
CLASS="constant"
><B
>ORACLE_HOME</B
></TT
> or
    <TT
CLASS="constant"
><B
>TNS_ADMIN</B
></TT
>.
   </P
></BLOCKQUOTE
></DIV
><DIV
CLASS="note"
><BLOCKQUOTE
CLASS="note"
><P
><B
>Nota: </B
>
    In PHP versions before 5.0.0 you must use <A
HREF="function.ocinlogon.html"
><B
CLASS="function"
>ocinlogon()</B
></A
> instead.
    This name still can be used, it was left as alias of
    <B
CLASS="function"
>oci_new_connect()</B
> for downwards compatability.
    This, however, is deprecated and not recommended.
