Web Scraping with PHP

Though web services are becoming increasingly popular for exposing
access to data, many service-oriented web sites still do not make
their data available for consumption by automated agents. Alternative
methods to interact with such sites are rarely documented and often
not obvious to developers without a good working knowledge of multiple
technologies that power the web today.

Web scraping is a collection of practices and techniques to simulate
the behavior of a normal web site user in order to effectively use the
web site itself as a web service. This can include both retrieving
data made available by the site and well as introducing new data into
the site. This presentation will define web scraping and showcase
recommended practices and common issues and solutions.
