system() does not work at certain times

[hexguy]

Hi,
I have a php file that uses system() command.But it gives me a blank screen when I give system("ping localhost") whereas it gives me a list of files when I give system("ls") and returns the directory name when I give system("pwd").What could be wrong?What should be changed.Please help me.
Thanks in Advance.

You probably have to put a count value in
ping -c5 localhost

You may have to specify the full path to ping.
What type of OS system ?
