PHP while loop doesn't work

[madmadmax]

if ($playercards>21 || $choice==1)

{

while($dealercards<17)

{

$key2 = array_rand($_SESSION['sesscards']);

$pick9 = $_SESSION['sesscards'][$key2];

unset($_SESSION['sesscards'][$key2]);

array_push($_SESSION['dealercards'], $pick9);

$dealercards=EvaluateHand($_SESSION['dealercards']);

$strd.="$pick9|";

}

....

}

 

This code seems to add the same card duplicated over and over again even though I use the same code outside of a while loop and it seems to work.

Edit: PLease provide the code from EvaluateHands!

Please put code in [php ] tags! (You can find a php-button in the editor)

What does EvaluateHand() look like?

 

For what it's worth, the following code works:

 

<?php
$sesscards   = array(1,2,3,4,5,6,7,8,9,10,11,12);
$dealercards = array();
//if ($playercards>21 || $choice==1) {
while(array_sum($dealercards)<17) {
	$key2 = array_rand($sesscards);
	$pick9 = $sesscards[$key2];
	unset($sesscards[$key2]);
	array_push($dealercards, $pick9);
//		$dealercards=EvaluateHand($dealercards);
	$strd.="$pick9|";

	var_dump($dealercards);
	print '<br />';
}
//}
?>

First of all, you have to check the statement.

This statement must be true:

$dealercards<17

 

While Loops execute a block of code as long as a specified condition is true.

//		$dealercards=EvaluateHand($dealercards);
	$strd.="$pick9|";

	var_dump($dealercards);
	print '<br />';
}
//}
?>

 

Evaluate hand is irrelevant because it works great, the code also works great, the only problem is it adds the same card multiple times to $strd I get output like "5D|5D|5D|".

 

Thanks everyone for being so helpful but especially you cyberRobot for actually testing this.

Just in case you're still looking for help, have you tried displaying the session variable to make sure it contains what's expected as the loop executes?

 

<?php
//...


$key2 = array_rand($_SESSION['sesscards']);
$pick9 = $_SESSION['sesscards'][$key2];
unset($_SESSION['sesscards'][$key2]);

var_dump($_SESSION['sesscards']);  //see what the session variable looks like after unset()


//...
?>

 

 

 

Displaying the session variable should let you know if the value is being removed as expected.
