echo system('whoami');
?>

but when i tried to run this php from prompt it works perfectly
php test.php


i could'nt find reason y this is happening


please put ur thoughts

Probably PHP safe mode is enabled. Safe mode will prevent PHP, as invoked from Apache, from executing any executables except in precepicief directories (see the safe_mode_exec_dir parameter in your php.ini to see what this is set to). Believe me, safe mode is a good thing that helps prevent people from exploiting buggy PHP scripts to exploit your system (it's not perfect, or anywhere close, but it helps).

exec not working
 

i set safe_mode_exec_dir variable to "On" in php.ini but still not working
