I'm running PHP locally, so I have complete control over its installation.
Under windows however getting PHP to recognize another ini file (besides the
one in its installation directory) requires changing the registry
(especially if other php installations are running). As such, it would be
great to have the javabridge run php-cgi with a customized ini (using the -c
option supported by php-cgi) when i create an php engine from my standalone
java application.

Would it be difficult to change the JavaBridge code to implement this? I
understand you're not interested in doing this, but if you could point me in
the direction on where I could make such change, that would be great.

Cheers,
Bart

Yes.

Both still work. It's just that the java.so/php_java.dll extension is not necessary anymore (PHP >= 1.4).

It is even easier now that we've scrapped the java extension. Just install a servlet engine or J2EE server on a computer within your intranet and use:

  require_once("http://yourServer:8080/JavaBridge/java/Java.inc");

in your scripts to access it.

If you want to start Java with each PHP script invocation, use the JSR 223 API (Java >= 1.6):

  jrunscript -classpath JavaBridge.jar -l php testScript.php



> 	java_require(3rd party jar files...);

> 	$props->put("someval","sourcedir");

Yes. Just add a java_require(".../Java.inc") to your script.

I do remember needing to recompile the phpJava bridge whenever I  
upgraded my PHP version.  I assume you are saying by the above that I  
could no longer simply recompile the 3.2.1 bridge source with the  
latest PHP source to produce a viable bridge extension to PHP, is  
that right?

Are you speaking from the point of view of someone who is trying to  
access PHP from Java -or- call Java libraries from PHP?  I need to do  
the latter, call Java .jar files from PHP.  My applications are pure  
PHP web-based applications but I need to be able to make calls  
through a 3rd party java library (provided by a vendor of mine) from  
my PHP applications (all interactive Web sites) that processes credit  
card transactions.

It seemed easy with the old 3.2.1 version of the bridge since all I  
did was compile the bridge as a PHP extension and then make simple  
calls from within my PHP.  Here is a stripped down (but nearly  
complete) example of the main script I use that communicates with our  
vendors merchant processing platform via their Java API called from  
our PHP web application:

	java_require(3rd party jar files...);
	$props = new Java("java.util.Properties");
	$props->put("someval","sourcedir");
	etc...
	$request = new Java("java.util.HashMap");
	..fill $request with all calling variables...

	try {
		$reply_class = new JavaClass("com.vendor.ws.client.Client");
		$my_reply = new JavaClass("java.util.HashMap");
		$my_reply = $reply_class->runTransaction($request , $props);

		$vendor_reply = java_values($my_reply);					//--- bust reply values  
back into PHP readable array

	} catch (java_exception $err) {

		handle errors

	}

Is it possible to do the same thing with the latest release similar  
to this.  Also if there is not a way for me to create the same  
javaBridge PHP extension as in the old 3.2.1 version, is the pure PHP  
implementation still available?

Thanks again for the great assistance.

Also if there are any other OS X users out there, feel free to jump  
in with any suggestions/help you may have for me.

I think PHP tries to load a php.ini from the current directory, if it exists. 

But I have the gut feeling that this is a bug. System administrators should be able to customize the php installation, not users.  Furthermore there may be more than one PHP version installed, php 4 for example doesn't understand any of the new php 5 config settings.

Hi all,

I'm trying to start the PHP/Java bridge on Windows from my Java application
with the code:

System.setProperty("php.java.bridge.php_exec",phpcgi);
manager = new javax.script.ScriptEngineManager();
e = manager.getEngineByName("php-invocable");

where the string phpcgi contains the location of the php-cgi.exe file, and
manager and e are globally declared.

In principle this works fine. However, now I am trying to get php-cgi.exe to
start with a customized ini file, not the default php.ini file contained
within the
php installation directory. Is it possible to set a system property for that
indicating which ini file is to be used?

Or do I need to start php-cgi.exe explicitly with -c option to accomplish
this?

Thanks,
Bart

Hi,

thanks a lot - this works now for me.

Remarks:
In a different answer you said to someone else:
"Until now this was only possible by asking the PHP object for its ID (through a Java method) and then fetching the object from a global array using the obtained ID as a key."
Isn't it correct to say:
"Before 5.4.3.1 this wasn't possible at all, but since 5.4.3.1 it is possible by asking the PHP object for its ID (through a Java method) and then fetching the object from a global array using the obtained ID as a key."?

Nevertheless this is still not exactly what I wanted/expected:
One still has to go back to Java once (using java_unwrap()) in order to retrieve the ID.
Even better would be an API in Java that would allow to directly send this ID.
I've seen the new methods JavaBridge.unwrapClosure() and PhpProcedure.unwrap().
I may try using these in order to make my solution even better...

Anyway, thanks a lot again for your time and help!

Regards Jürgen

the change is in the cvs head now. The current download version 5.4.3.1 also contains this feature. From the NEWS:

Hi,

I am attempting to install on CentOS using the method INSTALL.LINUX  
outlines:

	rpmbuild -tb php-java-bridge_5.4.3.1.tar.gz

However, I am hitting problems. The make processing fails with the  
following errors:

...

*.java php/java/bridge/http/*.java

error: Bad exit status from /var/tmp/rpm-tmp.16878 (%build)


RPM build errors:
     Bad exit status from /var/tmp/rpm-tmp.16878 (%build)

It would seem the GCJ v4.1 (the current stable release for CentOS)  
does not have the -ftarget=X flag, which was introduced in v4.2.  
Removing the flag from php-java-bridge-5.4.3.1/server/Makefile.am  
doesn't seem to help. I just get more errors.

My question is, does anyone have experience/advice with regards to  
installing on CentOS? Is there a way to avoid the above errors? Is  
there a ready to use RPM for CentOS?

Thank you for any help that can be provided.

Hello,
I am returning from vacation after a job year end rush 
and try to catch the backlog.
Tried to access the php-java-bridge SF repository and it 
showed no updates despite a 5.4.3.1 source tar.gz.
What can I do to access the repository? (maybe I am
doing something wrong after such time without accessing it)
There is not a web cvs browsing anymore at SF...

Hi again,

> Things seem to have changed significantly in the 5 stream.

not really. Version 4.x was a transition towards a pure Java implementation (PHP/Java Bridge 5).

Version 5 has a flag which enables backward compatibility (define ("JAVA_PREFER_VALUES", true)). See our API documentation for details.

Jost Boekemeier



      

Hi,


> java.so

Remove it. 

Whether or not it's a PHP bug or a bug in Apache, I don't care. Simply remove the Java extension and use the pure Java PHP/Java Bridge instead.

The java.so is unsupported since PHP/Java Bridge version 3.2.1.  Please see the NEWS for details.

Hi,

Just take the java code and replace all "·" with "->", "new xxx" with new java("xxx") and xxx.FOO with java("xxx")->foo to create the PHP code. Please note that the driver must be in the bootstrap classpath, see our FAQ for details. Or deploy the driver via the Bea-/Oracle-/Sun- application server deploy tool.

Yes. Although it is possible to use a pooled resource directly from the servlet, you may need o/r mapping, anyway.

You can find several Java examples which show how to fetch a JNDI resource.

I'm confused how that is relevant to my question. I must not have 
explained my problem sufficiently in my previous post.

We are running 4.3.3 fine now. We were previously running a version 
around 4.0.1.

When we upgraded to apache 2.2.9 using the same java.so we found that 
apache processes were hanging and not exiting. I got a backtrace from 
them that looked like:

This seems to be identical to the discussion I previously referenced.

Things seem to have changed significantly in the 5 stream. We will 
change our code to work with the new stream, eventually but it doesn't 
seem trivial.

you can either set register globals to On or use the $_POST array. Example:


function getRequest() {
  static $request = null;
  if ($request == null) $request = new Request($_POST);
}  
class Request {
  var $attr;

Hi all,

I'm a Java programmer, & a complete newbie when it comes to PHP.
I've recently moved a customer's website to a new host running tomcat 
5.5.14 on a homegrown flavor of Linux.
This website contains both PHP and Java/JSP.

All I'm really trying to do is get the tomcat webapp to handle *.php 
pages correctly.

I've setup web.xml as shown in examples (using the PhpCGIServet to 
handle *.php pages), and have placed links in the /WEB-INF/cgi directory 
to an existing php installation on the server (as well as a link  to 
this installation's ini file).

I have an HTML page as follows:
<html>
<body>
<form name="frm" id="frm" method="POST" action="test.php">
<input type="text" name="txtTest" />
<input type="submit"/>
</form>
</body>

The text.php page is as follows:
<html>
<body>
<? print(Date("1 F d, Y")); ?>
<?php
    echo "<H1>You entered " . $txtTest . "</H1>";
?>
</body>
</html>

When I submit from the HTML page to PHP page, the PHP is processed 
correctly (date is shown, "You entered" is shown), but the parameters 
passed across in the HTTP Post are not coming through.

Any idea how to proceed?

Rgds,
Assaf

Hi Jon,

the main problem with version 3.2.1 is the hook into the Zend evaluator (the java.so or php_java.dll). Because the PHP low-level API changes constantly, it is impossible to maintain version 3.2.1 or below (PHP/Java Bridge 3.2.1 will no longer work with PHP 5.3 or PHP 6).

>From Java's point of view a php-cgi (fast cgi executable) is a requirement. Otherwise you won't be able to run PHP interactively. As far as I know the interactive JSR 223 script engine is the only way to start a REPL. -- The php cli can be started with the -a flag, which emulates an interactive PHP session, but this doesn't really work well in practice:

$ php -a
php > foo();
crash


Of cause there are other PHP implementations, some are written in pure Java. But none of them is 100% compatible with the PHP script engine from php.net, which renders these implementations useless.

Hi Jost,

(sorry for the delay in this response - I sent this originally on the  
1/12 using the wrong email address)

In the environment I am using (and many other Mac OSX and Mac OSX  
Server users), the PHP module is an Apache SO and the PHP command  
line interface is actually a .bin executable and not a fast CGI.  I  
utilize a variety of CRON jobs and such that call the PHP command- 
line executable directly for non-interactive PHP scripts.  Since I  
don't use the php-cgi I am not sure adding one to the bridge package  
will help me or maybe other Mac OSX Server users.

In the version I am currently running, 3.2.1, I compiled the java  
bridge from your source files to run as an extension to PHP in Apache  
1.3.x and also to run from the command line PHP executable.

I am not sure if you have changed the overall structure of the bridge  
to no longer support this way of doing things or the original stand- 
alone pure PHP implementation of the bridge you used to have as well.

If there is still a pure PHP version of the bridge, maybe that is the  
way I should go.  Otherwise, I am not sure the best way to upgrade to  
the new bridge from version 3.2.1 (which is working great).

Jon

Peter,

we were talking about an optimation which fetches the PHP object associated with a Java closure.  

Until now this was only possible by asking the PHP object for its ID (through a Java method) and then fetching the object from a global array using the obtained ID as a key.
