Question

After the server PHP upgrade I am getting the following error with PHP Version 5 6 2 on Apache 2 0  A PHP Error was encountered Severity  Notice Message  Only variable references should be returned by reference Filename  core Common php Line Number  257   How can I fix this

this has been modified in codeigniter 2 2 1   usually not best practice to modify core files  I would always check for updates and 2 2 1 came out in Jan 2015

Edit filename  core Common php  line number  257  Before  return   config 0    amp   config     After    config 0    amp   config  return   config 0      Update  Added by NikiC  In PHP assignment expressions always return the assigned value  So   config 0    amp   config returns  config - but not the variable itself  but a copy of its value  And returning a reference to a temporary value wouldn t be particularly useful  changing it wouldn t do anything    Update  This fix has been merged into CI 2 2 1  https   github com bcit-ci CodeIgniter commit 69b02d0f0bc46e914bed1604cfbd9bf74286b2e3   It s better to upgrade rather than modifying core framework files

It s not a better idea to override the core common file of codeigniter  Because that s the more tested and system files      I make a solution for this problem  In your ckeditor helper php file  line- 65  if  k     end  array keys  data  config                return             Change this to--     segment   array keys  data  config         if  k     end  segment                 return                 I think this is the best solution and then your problem notice will dissappear
