Regular expression to split on whitespace but ignore a double-quoted string

I know I am /[\s]+/'

separating the string with spaces. I'm trying to expand on this to ignore any spaces in double quotes. So I want to Hello World

be split but not"Hello World"

preg_split('/[\s]+/', $string)

is the expression I'm using in PHP.

You can use PCRE verbs (*SKIP)(*FAIL)

to tell the regular expression to skip certain parts of the expression. So:

".*?"(*SKIP)(*FAIL)|\s+

will skip double quotes. Here's a demo of regex101:
