Simple Question- Trim str after whitespace

[HotShot99]

I have a simple string "one two three four".

I would like to 'trim' this string after the (first) whitespace, thus the above string would give "one".

Any help much appreciated.

<?
$string = "one two three";
$white_pos = strpos($string," ");

if($white_pos !== false){
  $string = substr($string,0,$white_pos);
}
?>

<? 
$string = 'one two three';
$array = explode (' ', $string);
echo $array[0]; // outputs "one"
?>

$string = 'one two three';
echo substr($string,0,strcspn($string, ' '));

Simply a matter of going through the string functions listed in the manual and seeing what they do. Who knows what else you might find along the way?
