ping domain name to get ip with php

so im probably dumb and this is probably very simple. I have a text file with around 300 domain names in it. I dont want to ping them manual so I am working on a simple little php script to ping the domain name return the ip address and then echo them

I have the domains in a text file i can read the file and output thenames but the second i try to ping them all i get is a blank list of

  • dots like i said probably missing somthing so dumb but I appreciate any help

     <?php

 $names = file('sites.txt');
 foreach ($names as $name) {
 $testping = exec("ping  $name");
  echo '<li>' . $testping . '</li>';
 }

  ?>

    new code** 

     $names = file('sites.txt');
 foreach ($names as $name) {

   $ip = gethostbyname($name);



  echo '<li>' . $ip . '</li>';
  }

   ?>

    If your end-goal is to get the ip address look into gethostbyname():

    $names = file('sites.txt');
 foreach ($names as $name) {
     $ip = gethostbyname($name);
     echo '<li>' . $ip. '</li>';
 }


    echo $ip;

    @BrandonBraner Exactly what I wanted to do too! The reason why only the last entry in the list works is because PHP reads the lines correctly but appends a character at the end. It doesn't do this for the last line - don't ask me why. Perhaps it's the new line character.

    To get round it, use substr:

        $names = file('mysites.txt');
foreach ($names as $name) {

   $mydomain = substr($name, 0, -1);
   $ip = gethostbyname($mydomain);

  echo '<li>' . $ip . '</li>';
  }

    Did the trick for me. All you then need to do is to add an empty last line in the list of domains.

    gethostbyname() will return the IP address for any domain you enter. http://php.net/manual/en/function.gethostbyname.php
