How Can I Secure My ADOdb Code from SQL Injection Attacks?

SQL Injections in ADOdb: Understanding Concrete Examples

SQL injection vulnerabilities arise when untrustworthy data is directly utilized in SQL queries without proper validation and encoding. Contrary to popular belief, SQL injections can occur via any input mechanism, including both POST and GET methods.

In your provided code snippet with the POST method, the use of mysql_real_escape_string() ensures the encoding of user inputs, preventing SQL injection attacks. However, it is crucial to remember that forgetting to call this function even once can leave your code vulnerable.

In the GET method example, the code again safeguards against SQL injections by employing mysql_real_escape_string(). However, it is essential to always treat data received from external sources as untrustworthy, regardless of its source.

To enhance security, consider utilizing modern PHP Data Objects (PDO) in conjunction with prepared statements. This provides an even more robust defense against SQL injection attacks by preventing unexpected data insertion into SQL queries.
