To run a script from web app:
http://mysite.com/?XDEBUG_SESSION_START=1
To run a script from CLI:
Terminal 1:
1. export XDEBUG_CONFIG="idekey=session_name" # נראה שהערך עוזר אם רצים כמה דיבגרים במקביל אבל אם רק אחד העיקר שמוגדר והשימוש הוא בפורט 9000 2.2. php myscript.php
Terminal 2:
1. vim 2.1. Press F5 (you have 10 sec to do step 2.2)

need Vim compiled with Python 2.6+ support not on rhel5. To chech in vim do
python import sys; print(sys.version)
runing is like the old version
<F5>: start/run (to next breakpoint/end of script)
<F2>: step over
<F3>: step into
<F4>: step out
<F6>: stop debugging (kills script)
<F7>: detach script from debugger
<F9>: run to cursor
<F10>: toggle line breakpoint
<F11>: show context variables (e.g. after "eval")
<F12>: evaluate variable under cursor
:Breakpoint <type> <args>: set a breakpoint of any type (see :help VdebugBreakpoints)
:VdebugEval : evaluate some code and display the result
<Leader>e: evaluate the expression under visual highlight and display the result
