Web scraping is a computer science technique for extracting information and data from web sites. In data mining research scraping and analysing of information is discussed. Practically web scraping is necessary if you want to develop a web application where you want to show customised information from various websites. For this you’ve to first scrap data from the sites and then apply some logic to filter the information.
Practically you can use different languages to write the program that will automatically search and collect the information. But if you’re PHP experts and want to use PHP for this kind of stuff here I am referring a book with PHP library. Practically I found this book is very helpful to learn the topic and their library is easy to use.
