php code that will add spaces in desired positions of the string

I have entries like this:

username08-15-1008-31-1174.86.60.91http://sitename.com/04442

Where:

• username = username ;)
• 08-15-10 = year
• the rest of the numbers ( 08-31-1174.86.60.91 ) represents another date and ip which do no interest me
• the url of the site
• the first 0 zero after the url is the site's pagerank which can vary from 1 to lets say 7
• the second and third number 44, represents the number of internal links
• the fourth and fifth number represents the number of backlinks

What I am looking for is a php code that will add "space" after:

• the username;
• the date;
• the IP (just before http)
• after the url;
• after the first number;
• after the third number

With this spaces I can echo my code, copy paste it into excel and with the help of the spaces I can separate the data into columns. This way, I can manipulate it, lets say the oldest sites, with the greatest number of backlinks and the lowest number of outgoing links. etc.

I am thinking of something like this, but I do not know how to add the spaces:

<?
$sites = array(
'username08-15-1008-31-1174.86.60.91http://sitename.com/04442',    
'username08-11-1009-05-1196.44.171.207http:开发者_开发百科//sitename.com/034'
);

foreach ($sites as $site)
{
// HERE WILL BE THE CODE    
echo $site;
}
?>

Hope you can help! Ty!

Ok, if I understood correctly, this should do the trick for you:

for($i = 0; $i < count($sites); ++$i) {
    $sites[$i] = preg_replace("/(\w*)(\d\d-\d\d-\d\d)\d\d-\d\d-\d\d([\d.]*)(.*\/)(\d)(\d\d)(\d*)/","$1 $2 $3 $4 $5 $6 $7",$sites[$i]);
    echo $sites[$i];
} 

Note that this assumes that your username consists of only letters, numbers or underscores, and that your URL will end with /.

You can use regex for that:

preg_match('/(\w+)(\d{2}-\d{2}-\d{4})-(\d{2}-\d{2})(\d+\.\d+\.\d+\.\d+)(.*)/',$string,$matches);

After this, just use $matches as array, to extract each part of string. Concate with whatever spacers you like. $matches[1].' '.$matches[2].'etc'
