Replace domain name string

Question

I have URLs in my string like below:

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

Looking to replace all URL like below:

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

In above string (URL + ups) is common to match. All URLs are started with either HTTP or HTTPS.

Answer 1

As suggested in comments, the way to parse URLs is with 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);

Maybe it's too late... For a single string:

$components = parse_url( $url);
return str_replace($components['host'], 'anydomain.com', $url);

Protocol in url required. If urls are array - run above in a loop

Answer 3

use:

$new_string = preg_replace("/(http|https):\/\/(?:.*?)\/ups\//i", "$1://anydomain.com/ups/", $old_string);

so for input string:

http://subdomain.domain.com/ups/a/b.gif
https://www.domainX.com/ups/c/k.gif
http://subdomain1.domain.com/ups/l/k.docx

the output will be:

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