XDebug profiling in PHP - can't get output

Question

I\'ve got a strange issue. I\'ve setup XDebug to profile a PHP application we\'re working on. I believe everything is setup correctly but I get no output when I run it. M

Answer 1

Comment out xdebug.profiler_output_dir and xdebug.profiler_output_name and see whether you can find the output under /tmp/.

Answer 2

Also, beware of access restrictions, such as access rights, groups, owner and SElinux...

Answer 3

The full path was required, not just the path:

xdebug.profiler_append=1
xdebug.profiler_output_dir ="/home/username/debug/xdebug/profiler_output_dir"
xdebug.profiler_output_name = "cachegrind.out.%s.%H"

Answer 4

There is also problem with /tmp folders on some distributions, i couldnt get output on centos 7 and then i found this

So, i have set

xdebug.profiler_output_dir=/home/jirka/profile

chmod 777 /home/jirka/profile and its ok now.

Answer 5

Another possible cause of this issue is the permissions on the folder of profiler_output_dir.

Adding write permissions to the group and owner resolved the issue for me:

sudo chmod go+w /home/dimitris/cachegrind/
