<?php
if (!isset($_POST['submit']))
{
	echo '
	<form action="" method="POST">
	text: <input type="text" name="text"><br>
	repeat: <input type="text" name="repeat"><br>
	<input type="submit" name="submit" value="submit">
	</form>
	';
}
else
{
	for ($i = 1; $i <= $_POST['repeat']; $i++)
	{
		echo $_POST['text'] . '<br>';
	}
}
?>

<?php
if (!isset($_POST['submit'])) 
{ 
    echo ' 
    <form action="" method="POST"> 
    text: <input type="text" name="text"><br> 
    repeat: <input type="text" name="repeat"><br> 
    <input type="submit" name="submit" value="submit"> 
    </form> 
    '; 
} 
else 
{ 
    if (is_numeric($_POST['repeat']) && $_POST['repeat'] <= 500)
		{
			for ($i = 1; $i <= $_POST['repeat']; $i++) {echo $_POST['text'] . '<br>';}
		}
		else
		{
			echo 'invalid repeat count';
		}
} 
?>
