for() problem

[Pig]

K, I must be missing something really obvious because I cannot get a stinking for() loop to work right. Can someone please take a look and tell me what I am missing?

<?php
$i = 0;
for($day = 1; $day < 8; $day++ )
{
	while( $i < 2400)
	{
		if( substr( $i, -2 ) > 0 )
			{
				$i = $i +100;
			}
		else
			{
				$i = $i +30;
			}
		echo("$day | $i<br>");
	}
}

?>

That should produce something like

1|30
1|100
1|130
...
2|30
2|100

and on and on, up to 7|2430. However, what I am getting is just the 1|n series. Any help is appreciated.

reset $i to zero after the while loop

<?
$i = 0;
for($day = 1; $day < 8; $day++ )
{
    while( $i < 2400)
    {
        if( substr( $i, -2 ) > 0 )
            {
                $i = $i +100;
            }
        else
            {
                $i = $i +30;
            }
        echo("$day | $i<br>");
    }
    $i=0;
}
?>

You forgot to reset $i after each inner loop ends

i.e.

<?php
$i = 0;
for ($day = 1; $day < 8; $day++)
{
	while ($i < 2400)
	{
		if (substr($i, -2) > 0)
		{
			$i += 100;
		}
		else
		{
			$i += 30;
		}
		echo $day . "|" . $i . "<br>\n";
	}
	$i = 0;
}
?>
