      In PHP versions before 5.0.0 you must use <A
HREF="function.ocidefinebyname.html"
><B
CLASS="function"
>ocidefinebyname()</B
></A
> instead. 
      This name still can be used, it was left as alias of
      <B
CLASS="function"
>oci_define_by_name()</B
> for downwards compatability. 
      This, however, is deprecated and not recommended.
