PHP use preg_match_all to extract attribute names from string

I'm using the following code to split a string into an array of matches:

$text = 'text required name="first_name" label="First Name"';
preg_match_all('/"(?:\\\\.|[^\\\\"])*"|[^\s"]+/', $text, $matches);
print_r($matches);

The result is:

Array
(
    [0] => Array
        (
            [0] => text
            [1] => required
            [2] => name=
            [3] => "first_name"
            [4] => label=
            [5] => "First Name"
        )

)

But I need the result to be:

Array
(
    [0] => Array
        (
            [0] => text
            [1] => required
            [2] => name="first_name"
            [3] => label="First Name"
        )

)

I tried this but it didn't work:

preg_match_all('/="(?:\\\\.|[^\\\\"])*"|[^\s"]+/', $text, $matches);

Can anyone tell me where I'm going wrong? Thanks

If you want to use preg_match_all here's a working code:

$text = 'text required name="first_name" label="First Name"';
preg_match_all('([a-zA-Z_]*[=]["][a-zA-Z_]*["]|[a-zA-Z_]*[=]["][ a-zA-Z]*["]|[a-zA-Z]+)', $text, $matches);
print_r($matches);

You can use pattern /\s(?![\w\s]+\")/ in preg_split() to split string by space that isn't in value.

$res = preg_split("/\s(?![\w\s]+\")/", $text);

Check result in demo
