So im making a scratch card system and i want it so that when the player wins if says you win but pulls a code from a txt file to display then ones its been used once it will delete outta file.
Index File
<?php
$win = 0;
$cards = 5;
$probability = 0.5;
function generateScratchCard($n,$p) {
$w = 0;
for($i = 0; $i<$n; $i++) {
$result = (mt_rand() / mt_getrandmax());
if($result >= $p) {
$w++;
}
}
return $w;
}
?>

<?php
$win = generateScratchCard($cards, $probability);
echo "var win = ".$win."; ";
echo "var cards = ".$cards."; ";
?>
var p = 0.5;
var scratched = 0;
function callback(d) {
scratched++;
if(scratched >= cards) {
if(win > (cards/2)) {
document.getElementById('result').innerHTML = '<?php include_once ("file.php"); ?>';
} else {
document.getElementById('result').innerHTML = 'You lose, but you can try again!';
}
}
}

function shuffle(o){ //v1.0
for(var j, x, i = o.length; i; j = Math.floor(Math.random() * i), x = o[--i], o[i] = o[j], o[j] = x);
return o;
};
window.onload = function() {
var container = document.getElementById('container');
var cardsArray = [];
for(var i=0, l=cards; i<l; i++) {
if(i<win) {
cardsArray[i] = true;
} else {
cardsArray[i] = false;
}
}
shuffledArray = shuffle(cardsArray);
for(var i=0; i<cards; i++) {
var scratchCard = document.createElement('div');
var backgroundImage;
if(shuffledArray[i]) {
backgroundImage = 'assets/images/win.png';
} else {
backgroundImage = 'assets/images/lose.png';
}
container.appendChild(scratchCard);
createScratchCard({
'container':scratchCard,
'background':backgroundImage,
'foreground':'assets/images/foreground.png',
'percent':40,
'coin':'assets/images/coin2.png',
'thickness':18,
'counter':'percent',

};

<style>
#container { margin: 50px auto; width: 900px; }
#container div { display: inline-block; vertical-align: top; }
#result { font-size: 15px; text-align: center; color: #514d4d; text-transform: uppercase; font-weight: bold; padding: 15px 0 15px; }
</style>
</head>
<body>
<div id="container"></div>
<div id="result"></div>
</body>
</html>
File.php that pulls from
<?php
$coupons = file("coupons.txt", FILE_IGNORE_NEW_LINES);
echo "Your Winning Code Is: ".htmlspecialchars($coupons[0]).".";
array_shift($coupons); // Removes the first coupon
file_put_contents("coupons.txt", implode("\n", $coupons));
?>
The Coupon now shows up thank to minipif, Next issue is the problem that no matter win or lose the coupon get deleted every time you refresh ?
and ideas ?
