phpstuty After modifying the listening port, apache cannot start

Question

Hello everyone: phpstuty listens to port 80 by default. After modification, phpstuty cannot be started after restarting. Why?

Answer 1

There are three places where you can directly modify the port that the Apache website listens to. 1. phpStudy settings - general port settings; 2. Site domain name management; 3. Apache directory - conf folder - httpd.conf file. It is worth noting that only modifying the httpd.conf file will not work. One of the other two places must be modified before the port can be set correctly
