To extract the number and names of the arguments from a function or function[something] to return ("arg1", "arg2"), we use the inspect module. The given code is written as follows using inspect module to find the parameters inside the functions aMethod and foo.
There are two ways to pass arguments to a function: by reference or by value. Modifying an argument that's passed by reference is reflected globally, but modifying an argument that's passed by value is reflected only inside the function.
There is a technical maximum of 255 parameters that a method can have.
You can use reflection...
$r = new ReflectionMethod($className, $methodName);
$params = $r->getParameters();
foreach ($params as $param) {
//$param is an instance of ReflectionParameter
echo $param->getName();
echo $param->isOptional();
}
