just try "if ($POS !== 0) {"
well, that said, isn't the first position in a string 0 ?
So, in the above example the OP would need
// This would mean that www. was found any where in the string
if ( $POS )
or
// Would mean that www. was found at the beginning of the string
if ( $POS === 0 )
Remember that in PHP land $var = 0 evaluates to FALSE. So strpos('foo',
'f') will return 0 (first char), which in an if() expression would turn
to false:
if(strpos('foo', 'f')) {
echo 'f found in foo';
} else {
echo 'f not found in foo, or maybe it is the first character; we can
not tell';
}
That's the reason people use strpos('foo', 'f) !== false since that
differentiates the false result (nothing found) from an integer result
(for the position it was found on).
