Code Golf: Conway's Game of Life

Answer 1

PHP - 365 328 322 Characters.

list(,$n,$l) = $_SERVER["argv"];
$f = file( $n );
for($j=0;$j<$l;$j++){   
    foreach($f as $k=>$v){  
        $a[$k]="";      
        for($i=0;$i < strlen( $v );$i++ ){
            $t = 0;
            for($m=-1;$m<2;$m++){
                for($h=-1;$h<2;$h++){
                    $t+=ord($f[$k + $m][$i + $h]);
                }
            }
            $t-=ord($v[$i]);          
            $a[$k] .= ( $t == 494 || ($t == 452 && ord($v[$i])==88)) ?  "X" : "." ;
        }
    }
    $f = $a;
}       
file_put_contents("out.txt", implode("\n", $a )); 

I'm sure this can be improved upon but I was curious what it would look like in PHP. Maybe this will inspire someone who has a little more code-golf experience.

• Updated use list() instead of $var = $_SERVER["argv"] for both args. Nice one Don
• Updated += and -= this one made me /facepalm heh cant believe i missed it
• Updated file output to use file_put_contents() another good catch by Don
• Updated removed initialization of vars $q and $w they were not being used
