An example of a text guestbook made in PHP (3)_PHP Tutorial

In the last two sections, I talked about guest.php and edit.php. What needs to be noted is the difference between php and html:
php is usually -->(1)
(2)echo("zihanonline");
">
echo(" zihanonline");
                                                                                                                                                                                                                                                                                             Management: manage.php code.
----------
//manage.php









< ;?
include('head.htm');
include("sys.php");
if ($password!=$managepwd and $dispflag)
{


echo "";
echo "

";
echo "Password Error! Unable to delete message!";
echo "

The program will return in 3 seconds

";
echo "

";
echo "
";
echo "";

exit;
}

?> ;


if ($dispflag=="show")
{
$content = file($guestfile);
$count =count($content);
$text="";
for ($h=$count;$h>0;$h--)
{
$text=$text.'nn"; [$h-1];
                                                                                                                                                                                                             ?>>
if ($submit)
{
if ($password!=$managepwd)
{
echo "";
echo "";
echo "Wrong password! Cannot delete message!" ;
echo "

";
echo "

";
  echo "

  echo "";

  exit;
  }

  if ($password==$managepwd)
  {
  $guest_content=file($guestfile);
  $count=count($guest_content);
  for ($j=1;$j<=$count;$j++)
   {
   $del_rec_num="check".$j;
   $del_num=$$del_rec_num;
   //echo "$del_num:$del_num";
   $guest_content[$del_num-1]="";
   }

  $fp=fopen($guestfile,"w");
  for ($i=0;$i<=$count-1;$i++)
  {
  if ($guest_content[$i]!="")
   {
   fputs($fp,$guest_content[$i],strlen($guest_content[$i]));
