Split vars. with a minus (-)

[kumschick]

Hi,

If I want to split a varsable every 6 chr. , who do I do this?

$vars = "ygfDfDVwBefDawBepzygjdygpzkLVwlukLpzaw";

This way -> ygfDfD-VwBefD-awBepz-ygjdyg-pzkLVw-lukLpz-aw

I tryied it with "strlen()" and "replace()", but it doesn't work as i want!

Nothing happens at the result with my script, I was even so angry that I delete the scipt. :bemused:

Thx

$vars = 'ygfDfDVwBefDawBepzygjdygpzkLVwlukLpzaw';
$output = '';
for($i=0;$i<strlen($vars);$i++) {
   $output .= $vars{$i};
   if((($i+1) % 6) == 0) {
      $output .= '-';
   }
}

echo $output;

If you're using php5, use [man]str_split[/man].

There's also [man]chunk_split[/man].

and wordwrap()

 echo wordwrap("hghfdhgjtyeytthkdhfjthfdhd", 6, "-", 1);
