Goutte is a PHP library used for web scraping and web crawling, offering an intuitive API for navigating websites and extracting data from HTML/XML responses. Despite being deprecated as of April 2023, it remains functional for tasks such as extracting data from web pages and exporting it as a CSV file. The guide provides a comprehensive tutorial on setting up Goutte for a web scraping project, detailing steps like installing necessary dependencies, configuring a project, and implementing data extraction and pagination logic. It also addresses the limitations of using Goutte, such as its inability to handle JavaScript-heavy pages and its susceptibility to anti-scraping measures, suggesting alternatives like Symfony’s HttpBrowser and other PHP libraries for more robust solutions. Additionally, it highlights the potential of using a Web Unlocker API to bypass anti-scraping protections and the importance of maintaining a flexible and maintainable web scraping script.
