SQL (Structured Query Language) is a powerful language for working with relational databases, but quite a few people are in fact ignorant of the dark side of this language, which is called SQL-injection. Anyone who knows this language well enough can extract the needed data from your site by means of SQL – unless developers build defenses against SQL-injection, of course. Let’s discuss how to hack data and how to secure your web resource from these kinds of data leaks!

Web parsing php tools
Almost all developers have faced a parsing data task. Needs can be different – from a product catalog to parsing stock pricing. Parsing is a very popular direction in back-end development; there are specialists creating quality parsers and scrapers. Besides, this theme is very interesting and appeals to the tastes of everyone who enjoys web. Today we review php tools used in parsing web content.
Sometimes when you are developing a project, it might be necessary to do a parsing of xls documents. To give an example: you do a synchronization between xls worksheets and a website database, and you need to convert xls data to the Mysql and want to do it completely automatically.

Web scraping or crawling is the act of fetching data from a third party website by downloading and parsing the HTML code to extract the data you want.

Recently we executed the CaptchaSolutions.com service testing. CaptchaSolutions.com provides an automated online captcha solver API service (the name speaks for itself). It also includes solving google reCaptcha 2.0. So we decided to test it against this challenging captcha.
If you want to compare the other services’ solving reCaptcha 2.0 test results, then please refer to this post
Question: Is there any way to include captcha on the site and at the same time prevent services like 2captcha from resolving it?
