What are the best practices for avoiding the use of eval() in PHP code?

Using eval() in PHP code can be dangerous as it allows for the execution of arbitrary code, opening up potential security vulnerabilities. To avoid using eval(), it is recommended to find alternative methods such as using built-in PHP functions or implementing a more secure approach, such as using conditional statements or functions. 

// Avoid using eval() to execute arbitrary code
$code = "echo 'Hello, World!';";
eval($code); // Avoid using eval() like this

// Instead, use built-in PHP functions or other secure methods
$code = "echo 'Hello, World!';";
echo $code; // Use this method instead of eval()
