What are the potential pitfalls of storing PHP code in a database and outputting it in HTML?

Storing PHP code in a database and outputting it in HTML can pose security risks such as SQL injection and cross-site scripting attacks. To mitigate these risks, it is recommended to sanitize and validate the stored PHP code before executing it. 

// Retrieve PHP code from database
$php_code = // retrieve PHP code from database

// Sanitize and validate PHP code
$php_code = htmlspecialchars($php_code);

// Execute PHP code
eval($php_code);
