Trying to spin a text based on conditions

What I am tring to do is ;
depending on the conditions (in this case if the domain is a .com domain ) then choose the first variation. If not, choose the second variation.

<?

$dom = $_GET['dom'];

function spin($var){
$words = explode("{",$var);
foreach ($words as $word)
{
    $words = explode("}",$word);
    foreach ($words as $word)
    {
        $words = explode("|",$word);
if ($dom = "com"){$word = $words[0];}
else {$word = $words[1];}
echo $word." ";
    }
}
}
$text = "<font size=\"6\">is this the domain {<b>.com</b> |<b>.us</b> } ?, so you are from {anywhere|usa} ?</font><br />";
spin($text);


?>

PHP:

 

$dom = parse_url($_GET['dom'], PHP_URL_HOST);

Code (markup):

And for the if matching 1 thing you could use is this.

if (preg_match('/\.com$/i', $dom)) {
    $word = $words[0];
}

PHP:

What all this should do is.
1. parse the get value from $_GET['dom'], which just returns domain, e.g - google.com , google.co.uk, subdomain.google.com etc etc
2. in the preg match we search for .com and indicate that the search string end after the pattern ($), so it dont match subdomain.commercial.net and the likes
Search using case-insentive (i), so it also macthes if one write .COM

For variations replace .com with .co.uk , .net etc
When you have more variations in iam sure it could be written using less code ( so not using if -> elseif -> elseif -> else )

 

For variations you may want to grab the TLD and use "switch" instead of "if"

 

thanks all but, my problem (way) is to spin the text, not get the domain name.

I was trying to spin the text based on what the domain was.

all sorted anyways.. thanks again.

 

Oh a little misread there , sorry
But good you got it sorted
