    Time To Create Page

    shows the loading time of a page.

    <?
    function getmicrotime(){
    list($usec, $sec) = explode(" ",microtime());
    return ((float)$usec + (float)$sec);
    }
    $time_start = getmicrotime();

    // start page content
    // this is dummy - content
    for ($i=0; $i <1000; $i++){
    }
    // end page content

    $time_end = getmicrotime();
    $time = $time_end - $time_start;
    $time = round($time,6);
    echo "This page loaded in $time seconds.";
    ?>

      i have an easier and shorter code that will do the exact same thing...

      Code:
      $time=number_format(microtime(),2);
echo "Script loaded in: $time Sec(s)";
      but thanks for this other code that was posted also..
      <?php
      include ('Ghost');
      if ($Post == true) {
      echo '

      sigpic
      alt='coding-talk.com!!' />';
      echo 'Sharing Is Caring!';
      } else {
      echo '

      alt='the username GHOST has been comprimised!' />';
      echo 'OMG SOMEBODY HELP ME!!';
      }
      ?>

        Good question.. I never thought of that but it would be a nice feature.. ir would be easy to get the size of the page but im not sure about ading the size of all images.. maybe there is a complete function for thisa on php.net.. mmm

              To get the size of each page is very simple one line of php but im really not sure how to total the images.. i will look into it later.

                a php function to get the size of a remote file without the need of download it.

                <?php

                {

                $path = $url_p["path"];

                $fp = fsockopen($host, 80, $errno, $errstr, 20);
                if(!$fp)
                { return false; }
                else
                {
                fputs($fp, "HEAD ".$url." HTTP/1.1\r\n");

                while (!feof($fp)) {
                $headers .= fgets ($fp, 12;
                }
                }
                fclose ($fp);
                $return = false;
                $arr_headers = explode("\n", $headers);

                  yes but that gets ONLY the file sixe, you can do it in a much smaller line than that with the file size php function.. it does not include images or css in the total eh... here is a class that will determine the true web page size but its a big clas and a waste of resources in my opinion...
