To connect a proxy for Instagram, you need to use third-party services. With their help, you can assign a separate proxy for each account, through which the profile will work. An example of a service is Instaplus. You can also use built-in proxies on the site.

To scrape currency rates, you can use various financial data sources that provide reliable and up-to-date exchange rate information. However, keep in mind that scraping financial data may be subject to the terms of service of the respective websites, and it's crucial to comply with their policies.

Here are some legitimate alternatives to scraping:

1. Use a Financial Data API: Many financial data providers offer APIs that provide real-time and historical exchange rate data. Examples include:

   • Open Exchange Rates
   • ExchangeRate-API
   • Alpha Vantage

   These services often require an API key, and they may have free and paid plans with different levels of access.

2. Central Banks and Financial Authorities: Some central banks and financial authorities publish exchange rate information on their official websites. For example, the European Central Bank (ECB) provides daily updated exchange rates.

3. Financial News Websites: Financial news websites often display live exchange rates. You can check websites like Bloomberg, Reuters, or CNBC.

Remember to always check the terms of service and licensing agreements of any data provider you choose to use. Using a legitimate API is generally more reliable and ensures that you're accessing accurate and authorized data.

Avoid scraping from websites that explicitly prohibit scraping or do not provide permission for such activities. Unauthorized scraping may violate terms of service and legal agreements.

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.

Open the control panel of your computer, find and select the item "Network connection", and then click "Show network connections", "Local network connections" and "Properties". If there is a tick next to "Obtain an IP address automatically", then no dedicated proxy has been used. If you see numbers there, it will be your address.
