[SOLVED] Need help constructing a for loop

[Trium918]

Ok, Im trying to write the classic I'm Thinking of a Number game.

The user generates a number between 1 to 100 and the computer

guesses the number. The user is able to choose from high to low.

My algorithm should always be able to guess the number in seven

turns or fewer.

 

The follow code works but I need to insert a loop that will

keep up with the number of guess so that it will stop when

it reaches seven turns. I tried everything , so could

someone please help me out by trying this code to see what you

can come up with. Like I said, this code already works.

 

 

   echo "<form method=\"GET\">";
   echo "<input type=\"submit\"  name=\"Guess\" value=\"Guess\">";   
   echo "<input type=\"submit\"  name=\"Higher\" value=\"Higher\">";   
   echo "<input type=\"submit\"  name=\"Lower\" value=\"Lower\">";   
   
   if($_GET["Guess"]){
   	  $guess=50;
  $count++;
  print"<h2>My first number is: $guess <br></h2>";
  $max = 100;
  $min = 0;
   }
   
    if($_GET["Higher"]){
   	  $min = $guess;
  $guess = round($guess + (($max - $min)/2));
  $count++;
  print"<h2>Now my guess is: $guess <br></h2>";
  print"max = $max min = $min </h2>";
  print"count = $count";
   }
   
    if($_GET["Lower"]){
   	  $max = $guess;
  $guess = round($guess -(($max - $min)/2));
  $count++;
  print"<h2>Now my guess is: $guess <br></h2>";
  print"max = $max min = $min </h2>";
  print"count = $count";
   }
   
   
    
   echo "<input type=\"hidden\"  name=\"count\" value=\"$count\">";   
   echo "<input type=\"hidden\"  name=\"guess\" value=\"$guess\">";   
   echo "<input type=\"hidden\"  name=\"max\" value=\"$max\">";  
   echo "<input type=\"hidden\"  name=\"min\" value=\"$min\">";  
   
   echo"</form>";

A for loop isn't the right structure here.  Sessions would be appropriate.

 

At the VERY TOP of your script, before ANY output at all, add

 

session_start();

 

Then, each time a guess is made, do

 

$_SESSION['guesses'] += 1;

 

Then, each time the script is run, also do

 

if ($_SESSION['guesses'] == 7) {
  echo "You're out of guesses!<br>";
}

The OP is already passing the number of guesses via the hidden field "count", so just testing

<?php
if ($_GET['count'] == 7)
?>

 

would work just as well.
