We use WSDL and SOAP to transmit data. But there is limited that we must know. VS 2003 don't know xsd:restriction and soapenc at WSDL document (if you still don't know about this, you can read before this). Without this element, we can not transmit array data. So, how can we solve this problem?

We can still use string to transport array. How? Example, we have array like this:

array(array('id'=>1,'title'=>'PHP API')
      array('id'=>2,'title'=>'PHP Web 2.0')
     )

We can manipulate become string such as:

1|PHP API#2|PHP Web 2.0

Each row is separated with # character, then each item is separated with #. This is basic idea.

Below, our WSDL:

<?xml version="1.0"?>
