Escape the dot in PHP sscanf?

Question

This doesn't work:

list($value) = sscanf('foo.bar','%s.bar');
echo $value; //foo.bar

While this does:

list($value) = sscanf('foo bar','%s bar');
echo $value; //foo

Any suggestions are really appreciated. Thanks.

You can use a basic (negated) character class instead of s as in:

list($value) = sscanf('foo.bar','%[^.].bar');
echo $value; //foo
