How can the call_user_func() function be used in PHP to pass parameters to a function without using eval()?
The call_user_func() function in PHP can be used to pass parameters to a function without using eval() by providing the function name and an array of parameters as arguments. This allows for dynamic calling of functions with variable parameters without the security risks associated with eval().
// Example of using call_user_func() to pass parameters to a function
function myFunction($param1, $param2) {
return $param1 + $param2;
}
$functionName = 'myFunction';
$parameters = array(2, 3);
$result = call_user_func($functionName, ...$parameters);
echo $result; // Output: 5
