[Php-java-bridge-users] Type Casting

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

This is not a Bridge problem, more of a question.  I am using the Java 
Bridge to access database servers from PHP.  Type casting is driving me 
nuts.  Does anyone have a preferred method of handling this? 

Should PHP handle everyting as a string and type casting be done in Java? 
I find the types are "difficult" when trying to pass objects.  Should 
everything be handled as primitives?

For example I have a Sql query being called from Java.  PHP passes a 
string and an int to the Java routine and the Java routine runs the SQL 
query and returns a double.  I have tried several different approaches and 
so far it isn't happy.

Any suggestions?

Hi,

can you please give an example which demonstrates the problem?

That's the only type that PHP supports, anyway. :)

The bridge will return a proxy for the result, which can be evaluated as usual:

  either 
    echo (int)(string)$sqlResult; 
  or
    echo java_values($sqlResult);

Note that the first line above might be wrong on 32 bit machines, where PHP int values have a limited range. Use (double)(string)$sqlResult instead.
