PHP Exec Ping Destination host unreachable?

What you need is preg_grep . Give this a try.

In_array will expect the whole string i.e. "Reply from 192.168.200.254: Destination host unreachable." . You can use strstr php manual strstr php function or regular expression check instead.

And since it's in the array - like someone suggested .. join the string of the array and try to find the text.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
