Stand Proxy

You need to go to "Settings", under "Sharing" select "VPN". And there you can either enter the connection parameters manually (address, port number, username and password), or choose a program that automatically connects the user to the proxy (free applications of this type can be found in Google Play).

The choice between using regular expressions and a library like PHP Simple HTML DOM Parser for scraping depends on several factors. Here are some considerations to help you decide:

1. HTML Parsing Complexity:

   • Regular Expressions: Regular expressions are not well-suited for parsing complex HTML structures. HTML is a nested and hierarchical language, and using regular expressions to handle all possible variations can lead to errors and difficulty maintaining the code.
   • PHP Simple HTML DOM Parser: This library is specifically designed for parsing HTML documents. It provides a convenient API for navigating and manipulating HTML elements, making it easier to work with complex HTML structures.

2. Maintainability:

   • Regular Expressions: Regular expressions can become difficult to read and maintain, especially as the complexity of HTML parsing requirements increases. They might not be the best choice for long-term maintainability.
   • PHP Simple HTML DOM Parser: Offers a more readable and maintainable way to interact with HTML. The library abstracts away many complexities and provides a familiar syntax for accessing and manipulating HTML elements.

3. Error Handling:

   • Regular Expressions: Debugging and error handling can be more challenging with regular expressions, especially when dealing with unexpected variations in HTML.
   • PHP Simple HTML DOM Parser: Provides better error handling and more descriptive error messages, making it easier to identify and address issues during the scraping process.

4. Performance:

   • Regular Expressions: In simple cases, regular expressions might have acceptable performance. However, for complex HTML structures, they can be less efficient compared to specialized HTML parsing libraries.
   • PHP Simple HTML DOM Parser: Designed for performance when working with HTML, and it is likely to provide better performance for HTML parsing tasks compared to regular expressions.

5. Learning Curve:

   • Regular Expressions: Learning and mastering regular expressions can take time, especially for beginners.
   • PHP Simple HTML DOM Parser: Offers a simpler and more intuitive interface, making it easier for developers to get started without a steep learning curve.

In summary, while regular expressions might be suitable for simple HTML parsing tasks, using a dedicated HTML parsing library like PHP Simple HTML DOM Parser is generally a more robust and maintainable approach, especially for complex HTML structures. It provides a higher level of abstraction, making it easier to work with HTML documents in a reliable and efficient manner.

To use free proxies, find a reputable proxy list, choose a proxy server, configure your browser or software, test the connection, monitor your connection, and be cautious due to potential security risks. Alternatively, consider using a paid proxy service for better reliability and security.

If you want to check the proxy's regionality, use a tool such as the proxy checker. You can either download the program or use it online. To perform the check, which allows you to determine not only the country and city, but also a number of other important indicators, you need to enter your username and password in the appropriate fields.

And it depends on what purpose the proxy is used for. But you should definitely give preference to paid proxies. They are more reliable, always available, and with that comes a guarantee of privacy. Unfortunately, personal data is often stolen from free proxies.
