What are the advantages and disadvantages of using eval() to execute PHP code from a file?

Using eval() to execute PHP code from a file can be convenient as it allows dynamic execution of code. However, it also poses security risks as it can execute arbitrary code which may lead to vulnerabilities such as code injection attacks. It is generally recommended to avoid using eval() when possible and instead use alternative methods like include or require to include files.
