See <a href="http://php.net/manual/en/function.debug-backtrace.php" rel="noreferrer">debug_backtrace</a> - this can trace your call stack all the way to the top.

Here's how you'd get your caller:

<pre><code>$trace = debug_backtrace();
$caller = $trace[1];

echo "Called by {$caller['function']}";
if (isset($caller['class']))
 echo " in {$caller['class']}";

Xdebug provides some nice functions. 

<pre><code>&lt;?php
 Class MyClass
 {
 function __construct(){
 $this-&gt;callee();
 }
 function callee() {
 echo sprintf("callee() called @ %s: %s from %s::%s",
 xdebug_call_file(),
 xdebug_call_line(),
 xdebug_call_class(),
 xdebug_call_function()
 );
 }
 }
 $rollDebug = new MyClass();
?&gt;
</code></pre>

will return trace 

<pre><code>callee() called @ /var/www/xd.php: 16 from MyClass::__construct
</code></pre>

To install Xdebug on ubuntu the best way is

<pre><code>sudo aptitude install php5-xdebug
</code></pre>

You might need to install php5-dev first

<pre><code>sudo aptitude install php5-dev
</code></pre>

 $str = "Called by {$caller['function']}";
 if (isset($caller['class']))
 $str .= " From Class {$caller['class']}";

 return $str;

<pre><code>echo debug_backtrace()[1]['function'];

Works since <a href="http://php.net/manual/en/migration54.new-features.php" rel="noreferrer">PHP 5.4</a>.

Or optimised (e.g. for non-debug use cases):

<pre><code>echo debug_backtrace( DEBUG_BACKTRACE_IGNORE_ARGS, 2)[1]['function'];
</code></pre>

The first argument prevents to populate unused function arguments, the second limits the trace to two levels (we need the second).

I just wanted to state that flori's way won't work as a function because it will always return the called function name instead of the caller, but I don't have reputation for commenting. I made a very simple function based on flori's answer that works fine for my case:

<pre><code>class basicFunctions{

 public function getCallerFunction(){
 return debug_backtrace( DEBUG_BACKTRACE_IGNORE_ARGS, 3)[2]['function'];
 }

}
</code></pre>

<h2>EXAMPLE:</h2>

<pre><code>function a($authorisedFunctionsList = array("b")){
 $ref = new basicFunctions;
 $caller = $ref-&gt;getCallerFunction();

 if(in_array($caller,$authorisedFunctionsList)):
 echo "Welcome!";
 return true;
 else:
 echo "Unauthorised caller!";
 return false; 
 endif;
}

function b(){
 $executionContinues = $this-&gt;a();
 $executionContinues or exit;

 //Do something else..
}
</code></pre>
