It was introduced to help newcomers write functioning SQL commands without requiring manual escaping. It was later described as intended to prevent inexperienced developers from writing code that was vulnerable to SQL injection attacks. This feature was officially deprecated as of PHP 5.3.0 and removed in PHP 5.4, due to security concerns. [1]
A classification of SQL injection attacking vector as of 2010. In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
For instance, in PHP, using the htmlspecialchars() function to escape special characters for safe output of text in HTML and the mysqli::real_escape_string() function to isolate data which will be included in an SQL request can protect against SQL injection. Encoding output, which can be used to prevent XSS attacks against website visitors.

This opens the possibility for XSS attacks that incorporate their payload into the HTTP GET parameter name. As a security filter against XSS attacks, this program sanitizes the value it reads from $_GET["name"] via the htmlentities function.
SQL injection; Vulnerabilities in applications and services (e.g. web server software such as NGINX or content management system applications such as WordPress); [7] [8] File processing and uploading vulnerabilities, which can be mitigated by e.g. limiting the file types that can be uploaded; [8]
SQL injection attacks and cross-site scripting fall into this category. Memory safety . In memory-unsafe programming languages, lower-level issues such as buffer overflows and race conditions can be exploited to take partial or complete control of the software.
