问题描述
Is there a best practice (IDE-based?), a PHP/bash script or something else to
- get the execution time of a line
- get the execution time of a block of lines (for example line 17 to 42)
- get the execution time of a certain function or method
in PHP ? I'm currently stuck with self-built solutions that use microtime(), but that's a dirty, unhandy and slow method to do so. I'm especially interested in solutions with the major PHP IDEs like Eclipse, Netbeans, PHPStorm and VIM. A perfect solution would be a tool that tracks an entire application and provides execution time tracking for each line, each method and each custom block of actions.
I'll provide 50 bounty for a good answer.
This is what you are looking for: http://xdebug.org/docs/profiler. You can set up netbeans to attach to php process, than run scripts step by step, watch current variables content and analyze its running times.
Just add dll to other php extension, configure by php ini:
; xdebug
zend_extension = "C:phpv5.4extphp_xdebug-2.2.3-5.4-vc9-nts.dll"
xdebug.remote_enable=on
;xdebug.remote_log="/var/log/xdebug.log"
xdebug.remote_host=localhost
xdebug.remote_handler=dbgp
xdebug.remote_port=9000
xdebug.profiler_enable=1
xdebug.profiler_output_dir="C:devprofilling"
Netbeans setup:
Then press Ctrl+F5 in netbeans (debugging). Than you can run script step by step and watch current variables values:
To browse generated profilers log use http://sourceforge.net/projects/precompiledbin/ or http://sourceforge.net/projects/wincachegrind/ in windows, or http://kcachegrind.sourceforge.net/html/Home.html for linux.
