[Php-java-bridge-users] Echo'ing a String produced from Java

[<php...@li...>]

Hello.
  I am trying to print a String to the screen (via html) that was
returned from a Java Object; however, when the String is printed to
the screen, has information about the string embedded.

Example:
Java
-----------------------------------
class JavaClass{
   public String toString(){
         return "JavaClass";
   }
}


PhP
-----------------------------------
 $out = $JavaClassInstance->toString();
 echo $out;
-----------------------------------

Output on the web page:
[o(String)JavaClass]

I've tried to cast it like so
$out  = (String) $JavaClassInstance->toString();
and/or
echo (String) $out;

Anyone know why this is happening?

Thanks

Hi,


> Output on the web page:
> [o(String)JavaClass]

I think you're right, it seems foolish to require an
explicit conversion from java.lang.String to string.

Please add the following code to the
php.java.bridge.JavaBridge.java:

public String ObjectToString(String ob) {
  return (String)castToString(ob);
}
 
After that all java.lang.String objects are displayed
as a string value, even though they are still string
objects:

$s = new Java("java.lang.String", "hello world");
echo $s;
echo "\n";
echo $s->substring(0,5);

=> hello world
=> hello

I have uploaded 4.0.3 for testing, it already contains
this code.

Thank you very much for the bug report.


> I've tried to cast it like so

That worked with the C based extension, but
object->value casts do not work on PHP level. That's a
shortcoming in the php engine, imho.
