Since the PHP array type is not directly compatible with a HashMap -  
even though they are basically the same concept of key/value pairs -  
you have to be careful when moving values back and forth between the  
two.  I have found that building a PHP array with all the values I  
need first and then using a simple FOREACH loop to populate my Java  
HashMap works great.  Here's an example:

<?php
...
// build a request array
$request['key1'] = "value1";
$request['key2'] = "true";
$request['key3'] = 2342;
$request['key4'] = "internet";

// == Prepare the request HashMap for Java ==
$j_request = new Java("java.util.HashMap");
foreach ($request AS $key => $val) {
	$j_request->put($key,stripslashes($val));
}

// To get your PHP array back from a HashMap just use the following
$original_request_array = java_values($j_request);

...
?>
Since Java is so strongly "typed" I have also run into a lot of  
problems with PHP's loose typing and Java.

Hope this helps a bit.

Nope.  This is just an issue with data types between PHP and Java.  I  
don't think you missed anything in the docs.  The doc's for the  
Bridge don't really discuss the intricacies of handling different  
data types between PHP and Java.  Maybe that is a good section to add  
to the documentation.  I'll add that to my list.

I'm using php-java-bridge-3.1.8, and have run into something really 
confusing when creating
HashMaps.

I have a method in a Java class that accepts a HashMap.  If I create an 
empty HashMap in
php and add elements with put like this:

$h = new java("java.util.HashMap");
$h->put(0 , "Some Text");

...and pass that to my class I can get it's value with get(0) no problem.  
However if I create
the HashMap in php with something like this:

$h = new java("java.util.HashMap", array(0=>"Some Text"));

...and pass that to the java class it wasn't able to get the key 0.  Also, 
trying to use $h->get(0)
within php didn't work either.

What I found is that the key to the resulting HashMap using the latter 
syntax isn't an
Integer 0, but rather an Object of the class 
php.java.bridge.Request$PhpArrayKey.

I see that creating a Vector directly from an array in a similar manner such 
as:

$h = new java("java.util.Vector", array(44.6, 5, 5.6, "some string"));

...works fine, and I get elements with all the expected data types in java.

Is this the expected behavior and possible something I missed in the 
documentation?  It had
me going for hours.  I see that there's at least one other email on the list 
were someone
couldn't read a value with get()...possibly the same issue.

Thanks in advance.

Tom

Hi all,

I am trying to build an install php java bridge on my centos 4.4 box.
But I alway got an error I don't understand.

rpmbuild --rebuild php-java-bridge-3.1.8-1.src.rpm

Libraries have been installed in:
   /usr/src/redhat/BUILD/php-java-bridge-3.1.8/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
