The PR query tool I wrote is like this, but there is one thing to note. PR queries are sometimes a bit slow. Some people ask why other people’s sites query quickly. In fact, many PR query sites have done various It's cached, because PR generally won't change unless Google PR updates, haha.

The above introduces the latest algorithm for obtaining Google PR value using PHP. Attached is the PHP query PR value code example, including PR content. I hope it will be helpful to friends who are interested in PHP tutorials.
