[Php-java-bridge-users] Alternative to try/catch with PHP 4?

[Abbett, J. <Jon...@ch...>]

Is there a PHP 4 alternative to using PHP 5's try/catch functionality to =
catch Java exceptions?

Hi Jonathan,

Currently only java_last_exception().

But funny that you mention it, I have just thought
about this while trying to do the opposite: find a way
to signal an exception while running a PHP procedure
invoked from java.


I think there are at least two solutions, we could
either add a primitive to register a "global"
exception handler, something like:

  java_register_exception_handler(php_proc);

or we could add a special primitive
"java_call_with_exception_handler" which wraps the
current invoke, getsetprop or create call and invokes
the handler in case we receive an exception- instead
of an object-handle (the protocol uses E to tag an
exception object).

Hi,

this has been implemented in version 2.0.8. A preview
is at
http://prdownloads.sourceforge.net/php-java-bridge/php-java-bridge_2.0.8pre.zip?download

Please see the examples/XML for an example how to call
php code from java.  The trick is to write a java
class which calls your PHP functions. On java level
you can catch the PHP exceptions and decide what to
call next:

interface Proc {
  public void f();
  public void e(Exception e);

  class test {
  public void call (Proc p) {
   try {
    p.f();
   } catch (Exception e) {
    p.e(e);
  }
}
<?php
function f() {
  new java("java.lang.String", null);
  echo "never reached";
}
function e($e) {
  echo "an exception occured on php level: $e";
}

$test=new java('Proc$Test');
$test->call(java_closure());
?>
