php - 替换域名字符串

Question

我的字符串中有如下 URL:

subdomain.domain.com/ups/a/b.gif
www.domain.com/ups/c/k.gif
subdomain1.domain.com/ups/l/k.docx

希望替换所有 URL，如下所示:

anydomain.com/ups/a/b.gif
anydomain.com/ups/c/k.gif
anydomain.com/ups/l/k.docx

在上面的字符串中(URL + ups)是常见的匹配。所有 URL 都以 HTTP 或 HTTPS 开头。

Answer 1

正如评论中所建议的，解析 URL 的方法是使用 parse_url() .

<?php
$urls = [
    "http://subdomain.domain.com/ups/a/b.gif",
    "https://www.example.com/ups/c/k.gif",
    "https://subdomain1.domain.com/ups/l/k.docx",
];
$domain = "anydomain.com";
foreach ($urls as &$url) {
    $u = parse_url($url);
    $url = "$u[scheme]://$domain$u[path]" . (isset($u["query"]) ? "?$u[query]" : "");
}
print_r($urls);
