Replace square-braced placeholder with new text

Question

I've this URL:

https://example.com/[photo-s]/photo.jpg

Sometimes the part between [] changes.

How in PHP, can I replace this part with another thing ?

Example:

preg_replace('photo-[a-z]', 'newphotopath', 'photo-s');

Answer 1

$url = 'https://example.com/[photo-s]/photo.jpg';
preg_replace('~\[(.*?)\]~', 'something_new', $url);

->

https://example.com/something_new/photo.jpg

If you mean to replace everything between .com/ and the following / regardless of having brackets or not you could use:

preg_replace('~.com\/(.*?)\/~', '.com/something_new/', $url)

->

https://example.com/something_new/photo.jpg

Answer 2

Code

$target = 'https://example.com/[photo-s]/photo.jpg';
$result = preg_replace('/\[photo-[a-z]+]/', 'somethingElse', $target);

Output

string(43) "https://example.com/somethingElse/photo.jpg"

Working example.
