是否有可能在PHP中的方法中获取语句？

Question

function mainFunction() {
  functionA(5, "blah");
  functionB("ok", "whatever");
}

How to write a function GetFunctions that returns the functions within mainFunction?

How to call them with the parameters given in mainFunction?

How to call them as follows?

foreach (GetFunctions(mainFunction) as $function) {
  print "Calling function $function: ";
  call($functionA); // called with parameters(5, "blah")
}

Working in PHP 5.2.8

EDIT: OK, here's a more complete explanation. I tried to keep it simple to make it easy to understand, but apparently that wasn't a good idea.

The goal is to call each assertion within a given static method. I am writing a testing framework. Each assertion returns true or false.

I am calling the methods as follows.

$methods = get_class_methods('LibraryTests');
foreach ($methods as $method) {
    if ( StartsWith($method, 'Test') ) {
        print "calling: " . $method . ": ";
        call_user_func('LibraryTests::' . $method);
    }
}   

The above code calls each method within the class, but I want to call each assertion individually and track the result (true/false). CallAssertion is supposed to call each assertion (such as TestUnit::AssertEqual(GetFormattedHour(5), "5 PM");). This is the method that I am asking about.

Here is the class:

class LibraryTests extends TestUnit {

    static $success = 0;
    static $failure = 0;
    static $total = 0;

    static function CallAssertion($assertion) {
        self::$total += 1;
        if ($assertion) { self::$success += 1; }
        else { self::$failure += 1; }
    }

    static function TestGetFormattedHour() {
        TestUnit::AssertEqual(GetFormattedHour(5), "5 PM");
        TestUnit::AssertEqual(GetFormattedHour(16), "4 PM");
    }

So, the question is, how to write CallAssertion?

Answer 1

You can't.

Instead, create a class and use reflection to get its methods.

Regardless, you'll want to figure out why this is necessary and see if there is an entirely different approach you can use.

(If this is for debugging purposes, you can use debug_backtrace to inspect but its purpose is not for calling functions as you have described in your question.)
