What does the webservice helper?

The webservice helper does what the name says: helping you making a php class available as webservice. It generates the documentation, the webservice description file (WSDL) and handles errorhandling. It consists of three parts:

• extension of the PHP reflection classes to also parse the comments for information on parameter info and return values. The documentation and WSDL are generated from these classes.(see also documentation.php as an example)
• extension to the PHP SOAP implementation. It catches all normal exceptions and allows typehints in the webservice methods. (ie. saveContact(contact $contact))

Installation

Use Composer to install the library. Package name: jelix/webservice-helper.

If you don't want to use Composer, you can copy the content of the source code (all needed classes are into lib/), and you must create an autoloader (like in example/common.php or you must include all classes.

Manual

So how do you create your own webservice. As an example we create a webservice to add and show contacts. First you create a class called contactManager in the /example/data_objects with the public functions getContacts(), saveContact(contact $contact) and newContact(). To let the Webservice helper know what the parameters and return values of each method are we put a comment in front of each method specifying the parameters and return types. For example:

We used the contact type as a return value for newContact() and getContacts() so we need to define what a contact looks like. For that we create a class called contact:

Since string is (just as boolean and int) a known datatype we don't need to specify it any further.

The last thing we need to do to finish our webservice is to tell the webservice that de contactManager class is an allowed webservice and that contact is an allowed data- structure (for documentation purpose and classmap). In the config.php you add "contactmanager" to the WSClasses array and add "contact" to the WSStructures array.

You can now view the service documentation at /doc/documentation.php and the wsdl at /example/service.php?class=contactManager&wsdl

Note about associative array containing objects: if the soap server defines a classmap ('classmap' option to SoapServer in PHP), objects are wrapped into SoapVal objects, else they are simple stdClass objects.
