<para>
<function>ocidefinebyname</function> binds PHP variables for fetches
of SQL-Columns. Be careful that Oracle uses ALL-UPPERCASE column-names,
whereby in your select you can also write lowercase.
<function>ocidefinebyname</function> expects
the <parameter>column_name</parameter> to be in uppercase. If you
define a variable that doesn't exists in your select statement, no
error will be given!
</para>
<para>
If you need to define an abstract datatype (LOB/ROWID/BFILE) you
need to allocate it first using
<function>ocinewdescriptor</function>. See also the
<function>ocibindbyname</function> function.

<para>
This function was renamed to <function>oci_define_by_name</function>
after PHP >= 5.0.0. For downward compatibility
<function>ocidefinebyname</function> can also be used.
This is deprecated, however.
