Teaching objectives
At the end of the training, the participant will be able to:
Creating classes to feed Web Services
Create various functions returning data in XML and JSON formats
Implementing a REST Web service in CRUD mode
Design web pages that use Web services
How to implement a REST service using a PHP framework

Intended audience
PHP developers, project managers.

Prerequisites
Good knowledge of PHP in a Web context (procedural and object-oriented). Basic knowledge of XML and JavaScript desirable.

Practical details
Hands-on work
Development of a CRUD web application in REST mode.

Course schedule

1
A reminder of Object-Oriented Programming

  • Class, instance, properties and methods, visibility.
  • Inheritance, interface, abstract classes.
  • Automatic methods and overload.
Hands-on work
Creation of the ADO (Abstract Data Object) class that will feed the Web Services.

2
XML, JSON, DOM, SAX and XPath

  • Well-formed XML document, basic rules.
  • Valid XML document: DTD or XSL.
  • The PHP DOM (analysis and creation).
  • XPath with PHP and validation with PHP.
  • SAX approach: XSLT transformers.
  • PHP functions for manipulating JSON format.
Hands-on work
Create a recursive DOM parsing function. Creation of an encoding/decoding function. Creation of an ADO class method, returning data in XML and JSON format.

3
REST approach

  • HTTP basics and reminders.
  • Other exchange formats: JSON, serialized PHP, MessagePack.
  • REST architecture components.
  • REST architecture design guides.
  • Logical versus physical URLs.
  • Error code definition.
  • Document a REST Web service.
  • ROA versus SOA / REST versus SOAP.
Hands-on work
Design a Web Service.

4
Implementing a REST Web service

  • Write Web Services: read, insert, update and delete data.
  • Transaction security.
  • The problem of hiding.
  • Mashup.
  • Testing a REST service: browser and testing tools.
Hands-on work
Create a Web Service in CRUD mode and secure critical operations. Configure feedback types. Creation of an RSS feed.

5
Implementing a REST Client

  • Invoke a Web Service in GET mode from PHP.
  • Use sockets and cURL to create a call context with other methods (PUT/DELETE/POST).
  • Error handling.
  • Specific features of the AJAX approach in XML and JSON mode.
  • Specific features of the AJAX approach.
  • Mashup insertion in DOM HTML mode.
Hands-on work
Implementation of a Web page consuming Web Services from several sources and presentation of aggregated results.

6
PHP frameworks

  • What is a framework?
  • Frameworks for creating REST APIs in PHP.
  • Setting up a Web Service with a framework.
Demonstration
Implementing a REST service using a framework.
PARTICIPANTS
PHP developers, project managers.

PREREQUISITES
Good knowledge of PHP in a Web context (procedural and object-oriented). Basic knowledge of XML and JavaScript desirable.
