I'm having trouble detecting whitespaces in strings.

Set up this test:

echo "<br>example 1:".intval(eregi("^\s","teststring"));
echo "<br>example 2:".intval(eregi("^\s","test string"));

Both resulting in 0 (zero)

also tried [:space:] and [:blank:] without result

Who can help this regular newbie expressing himself ?
