    $charactersLength = strlen($characters);
    $randomString = '';
    for ($i = 0; $i < $length; $i++) {
        $randomString .= $characters[rand(0, $charactersLength - 1)];
    }
    return $randomString;
}

// Echo the random string.
// Optionally, you can give it a desired string length.
echo generateRandomString();

?>

Example 2: php random string:

<?php
class Random{
  public static function Numeric($length)
      {
          $chars = "1234567890";
          $clen   = strlen( $chars )-1;
          $id  = '';

          for ($i = 0; $i < $length; $i++) {
                  $id .= $chars[mt_rand(0,$clen)];
          }
          return ($id);
      }

  public static function Alphabets($length)
      {
          $chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
          $clen   = strlen( $chars )-1;
          $id  = '';

                  $id .= $chars[mt_rand(0,$clen)];
          }
          return ($id);
      }

  public static function AlphaNumeric($length)
      {
          $chars = "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
          $clen   = strlen( $chars )-1;

          for ($i = 0; $i < $length; $i++) {
                  $id .= $chars[mt_rand(0,$clen)];
          }
          return ($id);
      }
}

  echo Random::Numeric(6).'<br/>'; #Example output: "567268"
  echo Random::Alphabets(9).'<br/>'; #Example output : IAGRmZyJS
  echo Random::AlphaNumeric(10); #Example output: Gzt6syUS8M

?>
