    <para>
     This function binds the named PHP variable with a SQL parameter.
     The SQL parameter must be in the form ":name". With the optional
     type parameter, you can define whether the SQL parameter is an
     in/out (0, default), in (1) or out (2) parameter. As of PHP
     3.0.1, you can use the constants ORA_BIND_INOUT, ORA_BIND_IN and
     ORA_BIND_OUT instead of the numbers.

    <para>
     &return.success; Details about the error can be retrieved using the
     <function>ora_error</function> and <function>ora_errorcode</function>
     functions.
    </para>
    <para>
     <function>ora_bind</function> must be called after <function>ora_parse</function>
     and before <function>ora_exec</function>. Input values can be given  
     by assignment to the bound PHP variables, after calling 
     <function>ora_exec</function> the bound PHP variables contain the output
     values if available.
