This is how I would do it ...
<?
$fp = fopen('/path/to/file','r');
while(!feof($fp))
{
$line = trim(fgets($fp,4096));
if(strlen($line))
{
$arr = explode(' ',$line);
$numbers[] = $arr[0];
// if you want to make it remove the .'s then
// do $numbers[] = str_replace('.','',$arr[0]);
}
}
for($i = 0 ; $i < sizeof($numbers) ; ++$i)
echo $numbers[$i]."\n";
?>
