Please help me with PHP problem!

[neutronical]

Hi all,

Stuck on another problem. I have ip ranges in the format:

127.0.0.0 - 127.0.0.5 192.168.0.1 -192.168.0.5 192.168.0.6 - 192.168.0.9

So beginning number then 'space dash space' ending number space next beginning number...

I have a massive load of these as I am playing around with geo services.

But I cannot break them into an array. I'm guessing the easiest way is to use something like preg_split and set 'digit, space, digit' as the pattern (as the only times in the file the pattern 'digit, space, digit' appears is between two different ranges). I have no idea how to write these 'patterns' though, so if somebody could please help me out as I have been trying for hours now and its beginning to bug me!

Cheers In A
Dan

Are these all in one big long string? What jumps out at me is to use str_replace() to convert " - " (space dash space) to "-" (dash), and then explode() to select out pairs with the delimiter " " (space) into an array.

Your pattern isnt consistant. Try this

PHP Code:

<?php
$ax = '127.0.0.0 - 127.0.0.5 192.168.0.1 -192.168.0.5 192.168.0.6 - 192.168.0.9';

$ax=str_replace(' -','-',$ax);
$ax=str_replace('- ','-',$ax);

$array = explode(' ',$ax);
print_r($array);
?>
