PHP ping to get response with the ip address -


i'm trying ping ip address test ip address whether available or not. having trouble on using fsockopen function. had research on using 'ping','exec' function none of them seem workable.

here code test ip address:

<?php     $ipaddress = array("192.168.1.1","192.168.1.67");     $kiosk = array("kuantan (35)","utc kuantan (36)");      $checkcount = 0;     foreach(array_combine($ipaddress,$kiosk) $items => $kiosk){         $fp = @fsockopen($items,80,$errno,$errstr,1);          if(is_resource($fp)){             if($fp) {                  $status=0;                  fclose($fp);                  echo 'success<br/>';              }         }         else{             echo 'failed<br/>';           }      } ?>

both ip address can ping cmd prompt. 192.168.1.67 lead me 'failed', 192.168.1.1. or 127.0.0.1 showing me 'success'. there wrong?

your code not pinging tries open tcp connection on port 80. ping command uses icmp packets, 192.168.1.67 not accepting connections on port 80.

following chat catalyst here sample code send 2 packets , wait 2 seconds response. $retval 0 on success, 1 on packet loss, 2 on other error. on linux, windows command parameters bit different should able change it.

<? // unset variables first avoid mixing results previous calls $retval=-1; $output=array(); exec("ping 127.0.0.1 -c2 -w2 2>&1",$output,$retval); echo "return code: ".$retval."<br>\n"; echo implode("<br>\n",$output); ?>

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
