使用in_array函数在变量中找不到字符串

Question

I'm trying to search the array $outcome for the string "Destination host unreachable" and it doesn't work.

I'm not sure what I'm doing wrong and was wondering if someone could lend a hand?

   $ip = 192.168.1.30

   $pingresult = exec("ping -n 1 $ip", $outcome, $status);

   if ($status == 0) 
       {                                        
           if(in_array("Destination host unreachable", $outcome))
               {
                   echo "Unreachable";
               }
           else
               {
                   echo "Alive";
               }   
       }

P.S. Please note I'm on a Windows machine so the exit status is different to Linux etc.

Answer 1

you can also try.

if(array_search($outcome, "Destination host unreachable") !== false){
 echo 'not reachable';
}
