showing apache (php) errors to the web

I'm looking for a way to display errors that apache generates under

/var/log/apache/error_log 

for my colleagues who are working on the same project. The coding language is php.

First I tried to do a simple php readfile script, but since the file is only visible too the root user i was unsuccessful. I do not want to use things like 开发者_如何学Pythoncpanel or kloxo. can anyone help ?

To answer this properly we'd need to know a lot more about your setup.

/var/log/apache/error_log

Kind of implies that this some variant of Unix - but which one?

Does that mean you're trying to make the file available via HTTP or do the relevant users have shell accounts?

If its just the permissions problem you need to solve and it's one of the mainstream Linux variants, then it's probably setup to use logrotate, and the config files for logrotate will be in /etc/logrotate.d/httpd or /etc/logrotate.d/apache so go read the man page for logrotate then change the file to something like.....

/var/log/httpd/*log {
   missingok
   notifempty
   sharedscripts
   postrotate
      create 660 apache webdev
      /sbin/service httpd reload > /dev/null 2>/dev/null || true
   endscript
}

Here the 'create 660 apache webdev' makes the file owned by apache uid, webdev gid with permission -rw-rw----

That will then take effect for all future log rollovers. You still need to set the permissions on the directory, e.g.

chmod a+rx /var/log/apache
chmod a+rx /var/log

will give everyone read access to the directories

..and change permissions on the current files...

chgrp webdev /var/log/apache/*.log
chmod g+r /var/log/apache/*.log

You have to change error_log's file permissions in order to be able to read it.
