php - 使用 PHP 查找 URL 的一部分

Question

获取这个域:

http://www.?.co.uk/elderly-care-advocacy/mental-capacity-act-advance-medical-directive.html

我如何使用 PHP 找到第一个和第二个斜线之间的所有内容，而不管它是否发生变化？

即。老年护理倡导

任何 helo 将不胜感激。

Answer 1

//strip the "http://" part. Note: Doesn't work for HTTPS!
$url = substr("http://www.example.com/elderly-care-advocacy/mental-capacity-act-advance-medical-directive.html", 7);

// split the URL in parts
$parts = explode("/", $url);

// The second part (offset 1) is the part we look for
if (count($parts) > 1) {
    $segment = $parts[1];
} else {
    throw new Exception("Full URLs please!");
}
