Hi, > 1. BUG. There is no PHP4 version of library in The PHP/Java Bridge does not work on threaded HTTP servers, e.g. IIS, unless ZTS is switched on. ZTS is experimental in all versions below PHP 5 and I know of at least 3 incompatible ABI's since 4.3.2. So the question is: which version of PHP4 on windows should we support? Isn't it possible to compile your own php4 binary as described in the README? > 2. About 80% of windows distributive size is > php5ts.dll > Is it possible to make alternative -light version?

The java_closure() call currently accepts only interfaces, not classes. It would be nice if the Sun's dynamic proxy would accept a class, but it doesn't. If we want this, we must write our own proxy compiler.

I don't think it is easy, esp. for me. =) Probably It should be easier to create a proxy Java object, which will call invokable PHP functions where it needed.

Hi,

Well, people have a reason why they use php 4.3.2,
4.3.3 or 4.4.0 or 5.0.x. Certain extensions only work
in one of these versions.
So if users what to use a specific version of php for
which no binary exists, I usually ask them to compile
from source.

Which errors specifically?

I didn't think this is possible. PHP is missing
features which are essential for desktop applications.
For example it doesn't have threads; it relies on the
web server to provide an "execution environment".
There are other environments which support the PHP
programming language for example a php -> CIL compiler
exists for the MONO project.
> Yes, sometimes.
Okay. I think it is possible to split the zip file
into a "documentation" zip and a zip file which
contains the php_java.dll, the php.ini and a short
readme.
> I like things like unzip and run. Like any lazy user

I don't see how this could be automated. Some people
use IIS, others prefer apache.

Sorry, the parameters are documented in the
INSTALL.WINDOWS document only. The README is indeed a
little bit unix centric; unix users usually start the
bridge via the php-java-bridge.service script or via
the php-java-bridge command.
If you install with "rpm -i php-java-bridge*.rpm" or
by double-clicking on the .rpm, the RPM package
manager will automatically set this up.
AFAIK windows doesn't have such a setup program. But I
am not a windows expert, though.
> I don't think it is easy, esp. for me. =)
What I meant was: Isn't it possible to use
java_closure() for this? For example:
<?
class test {
function toString() {
$sys=new JavaClass("java.lang.System");
return "Hello java from php@" . $sys;
}
}
$t = new test();
$javaT = java_closure($t);
echo $javaT;
?>
=> [proxy0: "Hello java from php@100982"]
The problem is that Sun's dynamic proxy doen't accept
a super class, i.e. the parent class is always
java.lang.Object. There are several open source
implementations which change this.
But in practice I think this isn't an issue. You can
always delegate, e.g. use the decorator pattern.
Regards,
Jost Boekemeier

Something about PCRE, but the problem was in CVS version of PHP4. I downloaded 4.4.0 sources and compiled them successfully, but failed to build bridge.

Hi, > Isn't it possible for Java application to provide > execution > environment and call PHP interpretator for script > processing? Yes. This feature will be available with PHP/Java Bridge 3.0 which will be published in december. The version 2.0.8 already supports everything necessary to fully implement jsr 223 except that some methods are currently private. But if you make the Context class and the getContext() method public, you can already call php scripts from java: * "include" the php instance from the apache pool and pass it the current java continuation * the php instance closes over its environment (see java_closure) and passes it to the passed java continuation * in your java continuation you can call into the closure as often as you want. * when the java continuation (e.g. the service method) terminates all allocated php continuations terminate, too. Regarding the compilation on windows, Steven has posted an excellent article on the list, please see http://sourceforge.net/tracker/index.php?func=detail&aid=1322743&group_id=117793&atid=679233 Regards, Jost Boekemeier ___________________________________________________________ Gesendet von Yahoo!
