What are the potential security risks of using the eval() function in PHP?

Using the eval() function in PHP can pose security risks as it allows for the execution of arbitrary code, opening up the possibility of code injection attacks. To mitigate this risk, it is recommended to avoid using eval() whenever possible and instead use alternative methods to achieve the desired functionality, such as using built-in PHP functions or implementing a more secure approach.
