I happened that problem on a virtual server  when everything worked correctly on other hosting  After several modifications I realized that I include or require one works on all calls except in a file  The problem of this file was the code  lt   php     gt  At the beginning and end of the text  It was a script that was only  lt     and in that version of apache that was running did not work

This was a developer mistake - a misplaced ending brace  which made the above function a nested function   I see a lot of questions related to the undefined function error in SO  Let me note down this as an answer  in case someone else have the same issue with function scope    Things I tried to troubleshoot first    Searched for the php file with the function definition in it  Verified that the file exists  Verified that the require  or include  statement  for the above file exists in the page  Also  verified the absolute path in the require include is correct  Verified that the filename is spelled correctly in the require statement  Echoed a word in the included file  to see if it has been properly included  Defined a separate function at the end of file  and called it  It worked too     It was difficult to trace the braces  since the functions were very long - problem with legacy systems  Further steps to troubleshoot were this    I already defined a simple print function at the end of included file  I moved it to just above the  undefined function   That made it undefined too   Identified this as some scope issue  Used the Netbeans collapse  code fold  feature to check the function just above this one  So  the 1000 lines function above just collapsed along with this one  making this a nested function  Once the problem identified  cut-pasted the function to the end of file  which solved the issue

How to reproduce the error  and how to fix it    Put this code in a file called p php    lt  php class yoyo      function salt              function pepper            salt             y   new yoyo     y- gt pepper      gt   Run it like this   php p php  We get error   PHP Fatal error   Call to undefined function salt   in   home el foo p php on line 6  Solution  use  this- gt salt    instead of salt     So do it like this instead    lt  php class yoyo      function salt              function pepper             this- gt salt             y   new yoyo     y- gt pepper       gt     If someone could post a link to why  this has to be used before PHP functions within classes  yeah  that would be great
