这是我的数组输出：
Array
(
[0] => http://www.example.com/some-page/
[1] => http://www.example.com/another-page/
[2] => http://www.example.com/third-page/
[3] => https://www.example.com/ssl/
[4] => https://www.example.com/with-slash-at-the-end/
[5] => https://www.example.com/without-slash-at-the-end
[6] => /internal-link
[7] => /anther-internal-link/
[8] => https://www.my-own-domain.com/internal-link-too-but-with-absolute-path/
)
如何从该数组中只获取外部链接和内部链接？我不在乎哪一个。
此正则表达式似乎可以很好地查找internal link
(.*my-own-domain'.com.*)|(^'/.*$)

PHP代码
$re = "/(?:.*my-own-domain''.com.*)|(?:^''/.*$)/m";
foreach($str as $x) {
if (preg_match($re, $x)) {
echo $x . "" . "'n";
}
}
