Finding which method in the child class called the method in the base class

Question

I'm trying to get the name of the method from the child class that called my method in the base class. How can I go about getting this?

class MyBaseClass {
    protected static function mybasemethod() {
        // how can I get the name of the method that called this?
        // I'm looking for 'myothermethod'
    }
}


class MyClassA extends MyBaseClass {
   protected static function myothermethod() {
       self::mybasemethod();
   }
}

Yes, i'm trying to get some unique information about what's calling the method in the base class (for caching purposes I'm going to use it as part of a caching key). So in the base class method I want to get the name of the method in the child class that called it so in htis case it wold be 'myothermethod' — user391986, Jun 11 '15 at 04:44
Suggest you've got some typos in your example. You'd be looking for "myothermethod" not "mybasemethod", and `myothermethod()` would be calling `self::mymethod` not `mybasemethod()`? — scrowler, Jun 11 '15 at 04:44

To get the name of classes you can try the function get_class_methods() To know more use this link

<?php

class myclass {
    // constructor
    function myclass()
    {
        return(true);
    }

    // method 1
    function myfunc1()
    {
        return(true);
    }

    // method 2
    function myfunc2()
    {
        return(true);
    }
}

$class_methods = get_class_methods('myclass');
// or
$class_methods = get_class_methods(new myclass());

foreach ($class_methods as $method_name) {
    echo "$method_name\n";
}

?>

Thank you for inspiring today's learning opportunity. I have often idly wondered whether this could be done, but never bothered to investigate. Now, I know that it can, indeed, be done!

I tested the following code fragment in a routine that I am currently testing.

System.Diagnostics.StackTrace trace = new System.Diagnostics.StackTrace ( false );
System.Diagnostics.StackFrame frame = trace.GetFrame ( 1 );
Console.WriteLine ( "Calling method = {0}" , frame.GetMethod ( ).Name );

The output is as follows.

Calling method = UtilsExercises

UtilsExercises is the name of the method that called the routine into which I embedded the code.

The preceding example is an adaptation of the sample shown in the StackTrace Class documentation at https://msdn.microsoft.com/en-us/library/system.diagnostics.stacktrace(v=vs.110).aspx.

Until you called it to my attention, I didn't notice that the example was php, which says a lot about how similar the syntax is to that of C#, Perl, PowerShell, etc. — David A. Gray, Jul 11 '15 at 08:05
