PHP Loops for Newbe

[johann75]

Hello, I am new in php and have made only little so fare. I am trying to make a script, but the script stops. I dont know how loops work.

<?php

$lenkzeit = 4.5;

$lenkunter = 1;

$ruhezeit1 = 11;

$ruhezeit2 = 9;

$stunden1 = 0;

 

$km = 1000;

$kmh = 80;

 

$stunden0 = $km/$kmh;

$stunden01 = $stunden0;

 

while ($stunden01 > $lenkzeit){

$stunden1 = $stunden1 + $lenkzeit + 1;

$stunden01 = $stunden01 - $lenkzeit;    //Stops here

 

if ($stunden01 > $lenkzeit) {

$stunden1 = $stunden1 + $lenkzeit + $ruhezeit;

$stunden01 = $stunden01 - $lenkzeit;

}

}

if ($stunden01 < $lenkzeit) {

$srunden1 = $stunden1 + $stunden01;

$stunden01 = 0;

}

echo $srunden1;

?>

A typical loop:

 

$a = 1;

$b = 99

while ($a <= $b):

    echo $a;

    $a++;

endwhile;

 

 

You don't seem to have an endwhile statement in your loop.  I would suggest doing a little reading on the web.

 

ie:  google ---  While Loops in PHP and you will find 10000 examples if not more.

The OP's form is correct also. See here

 

Add these lines to the beginning of your script and tell us the error

 

ini_set ("display_errors", "1");
error_reporting(E_ALL);

Thank you DevilsAdvocate. There was one error. The variable $ruhezeit should be $ruhezeit1. The while loop is working now, but when the while is false, the rest of the script is not running, the last IF.  When the while is false, is jumps right to the ECHO without working through the last IF.

I just like to see fully qualified and expanded code, I am not one for shortform even if it is accepted.

That would mean the condition in the if isn't being met. I have no idea what language that is or what those are supposed to mean so that's as much as I can tell you

I think that's a countdown to World War 3
