Looking to profile my web app, I have added the following settings to my Applications php.ini file:
zend_extension = "C:\hqp\xampp_1.7.4\php\ext\php_xdebug.dll"
xdebug.profiler_append = 0
xdebug.profiler_enable = 1
xdebug.profiler_output_dir = "c:\hqp\xampp_1.7.4\tmp\profiles"
xdebug.profiler_output_name = "cachegrind.out.%s"
xdebug.profiler_enable_trigger = 1
In the httpd.conf file, a file is auto_prepended using the php value auto_prepend. The cachegrind.out.* file generated bears the name of this file (%s modifier in xdebug.profiler_output_name) and not the file that I actually looking to profile (for example the index.php file does not have a corresponding cachegrind.out.filepath_index.php)
Any idea what I am missing here?
It might be that you are producing two files, and the second one overwrites the first.
You can change following parameters in your php.ini :
xdebug.profiler_append=1
This should append both calls in the same file. source : https://xdebug.org/docs/profiler
xdebug.profiler_output_name = cachegrind.out.%u.%p.%r
This should make sure that if there are 2 files, their names should be different.
https://xdebug.org/docs/all_settings#trace_output_name for other modifiers.
