zend studio debugger does not stop on breakponts when debugging PHP web page

i installed xampp on Windows XP (php version 5.2.6 ) and then development studio 6.1.0.

the problem is that when debugging PHP Web page id does not stop on breakpoints.

here is my .metadata for the project:


<?xml version="1.0" encoding="UTF-8"?>
<launchConfiguration type="org.eclipse.php.debug.core.launching.webPageLaunch">
<booleanAttribute key="auto_generated_url" value="true"/>
<stringAttribute key="base_url" value="http://localhost/"/>
<booleanAttribute key="debugNoRemote" value="false"/>
<stringAttribute key="debugPages" value="debugAllPages"/>
<stringAttribute key="file_name" value=""/>
<booleanAttribute key="firstLineBreakpoint" value="true"/>
<stringAttribute key="name" value="Default PHP Web Server"/>
<booleanAttribute key="org.eclipse.php.debug.core.OpenInBrowser" value="true"/>
<booleanAttribute key="org.eclipse.php.debug.core.RunWithDebugInfo" value="true"/>
<stringAttribute key="org.eclipse.php.debug.coreconfiguration_delegate_class" value="org.eclipse.php.internal.debug.core.launching.PHPWebPageLaunchDelegate"/>
<stringAttribute key="org.eclipse.php.debug.corephp_debugger_id" value="org.eclipse.php.debug.core.zendDebugger"/>
</launchConfiguration>



Also should my php.ini does not have a debuggin section. What this section should look like for php Zend
debugger ?
