Check (if . exists) and Remove?

[Ethics]

Hey guys,

I was just trying to figure out how...

Check if a variable contains a . in it. Then remove everything after that dot.

Any help, or a point in the right direction would be appreciated.

Thanks,
Mario

$str = 'xewdwe dfew .fwefwef we f we f we .f wef';

$pos = strpos($str,'.');
if($pos!==false) {
    $str = substr($str,0,$pos);
}

echo '<p>',$str,'</p>';

oddz' code works well. You could also use the following which should also do the trick.

$str = 'xewdwe dfew .fwefwef we f we f we .f wef';
$str = strtok($str, '.');
echo '<p>', $str, '</p>';
