PHP preg_match URL段不起作用

Question

I have a string:

https://domain.tld/123456/api/v1/projects/45242457-foo-bar.json

And I'm trying to match '45242457-foo-bar' using:

preg_match('~"/projects/(.*).json"~', $url, $matches, PREG_OFFSET_CAPTURE);

This keeps returning zero matches. Why?

Answer 1

你需要逃避你的时期（和贪婪的*）：

~"/projects/(.*?)\.json"~
