Actually, the easiest way would be to either use real Web services, or set up a simple
HTTP exchange system. In other words, your Java program would use HTTP to send
(GET/POST) requests to a server running PHP
(http://server/getCustomerNames.php?lastNameLike=a), PHP would operate on the request
and return some parsable data to the Java program (XML or some proprietary format). If
the Java program is stand-alone, this would be a client/server setup. Getting PHP to
initiate an unprovoked communication to the Java program could be difficult, if not
impossible. If the Java program itself was listening for HTTP connections on a specific
port, and informed PHP of that port, then it could be a two-way communication pretty
easily.
If you mean JSP as opposed to a stand-alone Java program, then they can also exchange
data using HTTP. This setup could easily manage two-way communication.
It would be extremely chatty, and it would be slow for large amounts of information,
but it would work. I routinely call Perl scripts from JSP
(http://server/dir_listing.pl?dir=whatever) that return directory file lists off a Web
server that the JSP does not have direct access to. Admittedly the system isn't under
very heavy load, but it works well enough.
While typing the above, I actually got thinking, it _may_ be possible to get PHP to
open a persistent socket connection, in which case you could have Java send a PHP
resource a request to open a persistent socket connection back to the Java program (ala
http://server/connectBackToMe.php?myIP=w.x.y.z&myPort=22222), and from that point
forward communicate using that. Obviously you'd probably want to do this https://, and
include a username and password. Maybe POST the request from Java so the connection
information isn't on the URL... whatever, variations on a theme.

I think what you meant to say is that PHP is not compiled into something that would be
available using JNI, not that it isn't a "programming language".

I see nothing there that would exclude PHP from being a "programming language". If you
wanted to define some sort of relationship between "scripting languages" and
"programming languages", you would probably have to say that "scripting languages" are
a subset of the total collection of "programming languages" (all scripting languages
are programming languages but not all programming languages are scripting languages).
(Almost) anything that has variable assignment/manipulation, loops, and logical flow
control is a programming language. This allows such things as MS-DOS batch files or
Unix shell scripts (yes, I call them "scripts", but they were written using a
"programming language" by my definition, and I don't have a problem with that, even
though the "language" is typically a bunch of native internal or external OS utilities
strung together with some logic), but excludes things like HTML (which has no looping
or logical flow control).
> PHP5 is supposed to have pretty tight integration with Java, but I don't use 5 yet.
PHP5 has no more "integration" with Java then PHP4 did. Many object-oriented concepts,
object behaviours, and exception handling have been added which make it look a lot like
Java, maybe that's what you mean.

However, you'd still have to interact with PHP5 resources on the server in the way I
outlined above.
