What stands a '~' for in a regular expression?.

'\s*' means a possible space right?.
and []? a possible space?.

Is there a site where to find a list of options to use i a regular expression?.

PHP Code:

$pattern2 = "~(<div\s*.?>)~"; // seems to me to search for a div opening en div closing tag
$pattern3 = "~(<span\s*.?>)~"; // seems to me to search for a span opening en span closing tag
