Number of attempts to communicate with the host and unanswered time

Recommended Posts


I have a problem with writing a function that will display the number of attempts to communicate with the host that have not been answered, if the host starts responding again, the table should display, for example 0. The website addresses are taken from the MySQL database. The next column should display the time from which the communication with the host was lost and if it responds, it should display, e.g. OK. Please, give me some hints how to write it. Thanks in advance.

I do not know nothing working. Here code:

$dbhost="localhost"; $dbuser="root"; $dbpassword="xxxxxx"; $dbname="database1";
$conn = mysqli_connect($dbhost, $dbuser, $dbpassword, $dbname);
if (!$conn) {
echo "Error connection with MySQL" . PHP_EOL;
echo "Errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Error: " . mysqli_connect_error() . PHP_EOL;
$port = '80';
$result = mysqli_query($conn, "SELECT * FROM domens") or die ("Erro connection: $dbname");
print "<TR><TD>idt</TD><TD>Name</TD><TD>Working</TD><TD>Number of attempts</TD><TD>Time</TD></TR>\n";
while ($row = mysqli_fetch_array ($result)) {
$idt = $row[0];
$naame = $row[1];
$quantity = $row[2];
$time = $row[3];

$host = $name;
$numb_attemp = $quantity; 		
			$fp = @fsockopen($host, $port, $errno, $errstr, 30);

      print "<TR><TD>$idt</TD><TD>$name<TD>OK</TD><TD>0</TD><TD>$time</TD</TR>\n";
     $sql = "UPDATE addresses SET quantity = 0";
} else {
      print "<TR><TD>$idt</TD><TD>$nazwa<TD>OK</TD><TD>$numb_attemp</TD><TD>$time</TD</TR>\n";
       $sql = "UPDATE addresses SET quantity = quantity+1";

 if (mysqli_query($conn, $sql)) {
     echo "sql update";
    else {
        echo "sql no update";

print "</TABLE>";

Start by turning on the error reporting function of PHP. There are at least 3 that I've spotted.
