I am getting the following error from Apache   Sat Mar 19 23 10 50 2011   warn  mod fcgid  stderr  PHP Fatal error   require once    function require   Failed opening required   common configs config templates inc php   include path     usr share pear  usr share php   in  home viapics1 public html common configs config inc php on line 158  I am definately not an expert of Apache but the file config inc php  amp  config templates inc php are there  I also tried navigating to a test html page I placed in common configs  so I assume there is no rights issues going on  I also set the rights on config templates inc php to give everyone read  write  and execute rights  Not sure what to do at this point  I checked to see if there was a  usr share php directory and I found there was not but when I did yum install php it said it had the latest  Ideas

I was having the exact same issue  I triple checked the include paths  I also checked that pear was installed and everything looked OK and I was still getting the errors  after a few hours of going crazy looking at this I realized that in my script had this   include once     Mail php     instead of   include once      Mail php      Yup  the stupid parenthesis was missing  but there was no generated error on this line of my script which was odd to me

Hey I just had this problem and found that I wasn t looking at the folder location closely enough   I had  require once  vagrant public liberate   APP   vendor autoload php   What worked was   require once  vagrant public liberate vendor autoload php   It was very easy  as a beginner  to overlook this very unnoticeable issue  Yes I do realize that the require issue being logged points directly to the issue at hand  but if you are a beginner  like me  these things can be easily overlooked   FIX    Have a good look at the debug of      Dir      etc etc etc file php   then have your file system open in a different window  and map the two directly  If there is even the slightest difference this require will not work and the above error will be spat out

It s not actually an Apache related question  Nor even a PHP related one  To understand this error you have to distinguish a path on the virtual server from a path in the filesystem  require operator works with files  But a path like this                            common configs config templates inc php  only exists on the virtual HTTP server  while there is no such path in the filesystem  The correct filesystem path would be  home viapics1 public html common configs config templates inc php  where  home viapics1 public html  part is called the Document root and it connects the virtual world with the real one  Luckily  web-servers usually have the document root in a configuration variable that they share with PHP  So if you change your code to something like this require once   SERVER  DOCUMENT ROOT     common configs config templates inc php    it will work from any file placed in any directory  Update  eventually I wrote an article that explains the difference between relative and absolute paths  in the file system and on the web server  which explains the matter in detail  and contains some practical solutions  Like  such a handy variable doesn t exist when you run your script from a command line  In this case a technique called  quot a single entry point quot  is to the rescue  You may refer to the article above for the details as well

You could fix it with the PHP constant   DIR    require once   DIR       common configs config templates inc php        It is the directory of the file  If used inside an include  the directory of   the included file is returned  This is equivalent to   dirname   FILE     This directory name does not have a trailing slash   unless it is the root directory  1

Just in case this helps anybody else out there  I stumbled on an obscure case for this error triggering last night  Specifically  I was using the require once method and specifying only a filename and no path  since the file being required was present in the same directory    I started to get the  Failed opening required file  error at one point  After tearing my hair out for a while  I finally noticed a PHP Warning message immediately above the fatal error output  indicating  failed to open stream  Permission denied   but more importantly  informing me of the path to the file it was trying to open  I then twigged to the fact I had created a copy of the file  with ownership not accessible to Apache  elsewhere that happened to also be in the PHP  include  search path  and ahead of the folder where I wanted it to be picked up  D oh
