[Php-java-bridge-users] Is it possible to release Java memory inside a PHP request?

[Janno M. <jan...@tr...>]

Hi,

I'm using the bridge to make about 50000 calls to a Java method that takes 
ArrayList as a parameter (containing some Date, Integer and String objects) and 
returns a HashMap. My script causes java.lang.OutOfMemory error. Is there a way 
to destroy Java objects in PHP script and release memory? I've tried unsetting 
the objects in PHP and also calling garbage collector directly (via Runtime 
class) but it doesn't seem to help. I'm using PHP4 and JavaBridge version 
1.0.6a. Would newer versios work better for me? Any help greatly appreciated.

BR,
Janno

Php 4 does not release allocated handles. If you call:

for($i=0; $i<100000; $i++) $s=new String("123");

php 4 creates 100000 string objects which will be
released by the bridge when the script terminates.

Since PHP5 each string instance is released
immediately, so the VM cannot run out of memory, even
if the script runs forever.


So I would recommend to upgrate to the latest stable
php5 version, which is php 5.0.5, and to use PHP/Java
Bridge 2.0.8.
