? about regular expresions

[Anon]

Please help me understand some things in this example:
$search = array
("'<script[^{>]?>.?</script>'si",}

"'<[\/!]?[^<>]?>'si");

What does it mean [^>]*?
-One or more simbols that are not >
OR
-Ziro or more simbols that are not >

What does it mean 'si

Thank you

• means zero or more,
• means one or more
  s means "search accross lines" so your search can include newline characters
  i means "case insensitive"

vincent is right. Another addition: *? means it does the minimal search for [^>].. but that doesn't change anything here.

Another example of *? use:

"%foo%bar%foo2%"
"%(.)%" would return "foo%bar%foo2"
while "%(.?)%" would return "foo"

As you can see, there is no use for it here, because [^>] garantees that there won't be any ">" character that can be repeated several times.
