Get log entry with api

[mma]

Hi all !

I develop a small program (using PHP and API) and my small function doesn't return something

Code: Select all

$logerr=$client->__soapCall("Dispatch", array(
	$client->_login,
	$client->_password, 
	"LogObject" ,
	"GetLogEntry",
	"Type",'error',
	"What",'Message'
));

$logerr contains an empty string...Whereas I create an error just before and I can see it in my syslog. Where is my error ?
But GetLog works.
For information, I use OTRS 2.4.
