将HTML字符串转换为PHP数组

Question

Assuming an HTML string like this:

$str = '<p>Hello World!</p><p style="text-align:center"><img src="foo.png" /><br /></p>';

It is possible to convert it into an array like this?

[0] => '<p>Hello World!</p>'
[1] => '<p style="text-align:center">'
[2] => '<img src="foo.png" />'
[3] => '<br />'
[4] => '</p>'

I tried using DOMDocument many different ways but the problem seems to always boil down to parenting. I need to traverse the HTML without regard for parent/child relationships.

@olibiaz' Answer will do..

Just wanted to show another way of doing this using preg_split.

$str = '<p>Hello World!</p><p style="text-align:center"><img src="foo.png" /><br /></p>';
$flags = PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY;
$regex = '/(<[a-z0-9=\-:." ^\/]+\/>)|(<[^\/]+>[^<\/]+<\/[a-z0-9]+>)|(<[a-z0-9=\-:." ^\/]+>)/';
$parts = preg_split( $regex, $str, -1, $flags);

OUTPUT:

array (size=5)
    0 => string '<p>Hello World!</p>' (length=19)
    1 => string '<p style="text-align:center">' (length=29)
    2 => string '<img src="foo.png" />' (length=21)
    3 => string '<br />' (length=6)
    4 => string '</p>' (length=4)
