find a string...

Don't know which PHP you're using, but here your example returns FALSE.

With strpos() you have to be careful anyway, because strpos('this is a string', 'this') returns 0 (zero), not FALSE. The best way to deal with this is:

Code:

$haystack='This is a red car';
$needle='green car';
$check = strpos($haystack, $needle);

if (  $check===FALSE )
{
    echo 'Not found';
}
else
{
    echo 'Found';
}
