CS 328 - Week 8 Lecture 2 - 2016-03-09

*   after class, DID break up stored-subs-demo.php into:

    stored-proc-demo.php
    stored-funct-demo.php

*   remember: for a bind variable that's an Oracle function's
    return value (OR also for an OUTPUT parameter),

    the THIRD argument to oci_bind_by_name is the name of the
    (for us, PHP) variable to be SET by the desired call;

    *   and for these, oci_bind_by_name also requires a 
        4TH argument, the maximum size of what might be put
	into that variable by this call;

*   note: function oci_error lets you obtain the LAST error from
    and OCI command

    (returns FALSE if none found)

*   PHP does have try-catch

*   PHP can redirect (but a LITTLE clunkily)
    *   will demo that later;
