This summary highlights the importance of preventing PHP code injection attacks, which can compromise an application's integrity and put users' data at risk. To achieve this, developers should adopt secure coding practices, such as sanitizing user input, avoiding dynamic code execution, and using security linters to identify potential vulnerabilities. Utilizing static application security testing tools like Snyk Open Source and PHPStorm can also help detect code injection issues early on. By incorporating these measures into their development workflow, developers can create more secure applications that protect users' data and prevent malicious attacks.
