No, there aren't equal.
Use === and you'll see the difference.
At least the manual says that the == operator is named equal and the ===
operator is named identical. Actually I wanted to point out that null is
a bit of a special case in PHP:
$ php -r 'var_dump(null == 0); var_dump(null == array()); var_dump(0 ==
array());'
bool(true)
bool(true)
bool(false)
$ php -r 'var_dump((array) ""); var_dump((array) 0); var_dump((array)
null);'
array(1) {
[0]=>
string(0) ""
}
array(1) {
[0]=>
int(0)
}
array(0) {
}
+-0 on the foreach issue, but with the SPL Iterators I can see where
Marcus is coming from.
