$server->wsdl->addComplexType(
'Row',
'complexType',
'struct',
'all',
'',
array(
'id' => array('name' =>'id','type'=>'xsd:int'),
'info' => array('name' =>'info','type'=>'xsd:string'),
'description' => array('name' =>'description','type'=>'xsd:string')
)
);

//---- Big ----------------------------------------------------------------

$server->wsdl->addComplexType(
'Big',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array(array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'tns:Row[]'))

);

This i got from somewhere in this forum. If i change the last line
array(array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'tns:Row[]'))
To
array(array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'tns:Row[]')),
tns:Row

Then my web service gives some problem. I fetch mysql results by mysql_fetch_asso() function.
My question is, does tns:Row makes some difference? Actually i'm dont have much knowledge of WSDL.

Can somebody please explain the difference?

Thanks in advance.
