How to get current function name in PHP?

Last Updated : 11 Nov, 2018

The function name can be easily obtained by the __FUNCTION__ or the __METHOD__
magic constant.

Method 1 (Prints function name):
__FUNCTION__ is used to resolve function name or method name (function in class).

Example:

<?php 
class Test { 
  
    public function bar() { 
        var_dump(__FUNCTION__); 
    } 
} 
  
function foo() { 
    var_dump(__FUNCTION__); 
} 
  
// Must output string(3) 'foo'  
foo(); 
  
$obj = new Test; 
  
// Must output string(3) 'bar' 
$obj->bar(); 

Output:

string(3) "foo"
string(3) "bar"

Method 2 (Prints function and class name):
using __METHOD__.

<?php 
  
class Test  
{ 
    public function foo() { 
        var_dump(__METHOD__); 
    } 
} 
  
  
function bar() 
{ 
    var_dump(__METHOD__); 
} 
  
// Same As __FUNCTION__ 
bar(); 
  
$obj = new Test; 
  
// Output the fully qualified method name "ClassName::MethodName" 
$obj->foo(); 

Output:

string(3) "bar"
string(9) "Test::foo"

Note: this code is tested with php7.1
