Hey paulOr, try this:

PHP Code:


		
			
<?php
$aRange = range(555445, 555450, 1);

foreach ($aRange as $iValue)
{
    echo $iValue . '<br />';    
}
?>

What's the arguement "1" doing??

The third argument to range is for the step. In other words, how much the resulting numbers should differ by. For example, range(1, 20, 3) would result in an array with values 1, 4, 7, 10, 13, 16 and 19.

The 1 in the range specifies how much to step up by on each increment (or decrement). So if it was set to 2 then we would have:

555445
555447
555449
etc...

(Salathe beat me to it but I'll keep this in anyway :)

You could do a simple for loop as well.

PHP Code:


		
			
for($i = 555444; $i <= 555555; $i++)
{
    echo $i . '<br />';
}

I wrote a nice article about range over here. No doubt worth a read!

The one way, the only was, to make it easy to remember if you ask me. I am used to it since I make a lot of these loops, but you can also use while loops, instead of for and foreach. :)

A similar discussion going on in another part of TalkPHP! I'd always use the for loop as well, to be fair. I don't see the range function as having any other uses apart from that which can be achieved using the for loop. I imagine the range function itself contains nothing more than a for loop.
