<h3>PHP Script to print Floyd's Traingle</h3>
<form method="post">
Enter the limit: <input type="number" name="limit" />
<input type="submit" value="Print Floyd's Traingle" /><br /><br />
<?php
//check if the post data has some value
if(isset($_POST['limit']) && $_POST['limit']){
$limit = $_POST['limit'];
$a = 1;
for ($i = 1; $i <= $limit; $i++){
for ($c = 1; $c <= $i; $c++){
echo $a.' ';
$a++;
}
echo "<br>";
}
}
?>
</form>
</body>
</html>It’s a pretty easy program just see the above script to understand how it works.
