Another silly mistake you can do is copy recursive function from non class environment to class and don`t change inner self calls to $this->method_name()

i`m writing this because couldn`t understand why i got this error and this thread is first in google when you search for this error.

You dont have a function named assign    but a method with this name  PHP is not Java and in PHP you have to make clear  if you want to call a function  assign     or a method   object- gt assign     In your case the call to the function resides inside another method   this always refers to the object  in which a method exists  itself    this- gt assign

Mates   I stumbled upon this error today while testing a simple script   I am not using  class  function though so it take it with grain of salt  I was calling function before its definition  amp  declaration    something like this        try               foo                      catch  exception  e                           echo   e- gt getMessage                          function foo                           echo  blah blah blah                            so php was throwing me error  call to undefined function       This kinda seem classic programming error but may help someone in need of clue

you need to call the function like this   this- gt assign     instead of just assign
