Hello,
you just have to set a restart interval for Apache. Otherwise it will restart each time you edit php or web server settings.

I suggest to follow How to enable/disable graceful restart for Apache? to change the Apache restart to an Apache reload (graceful restart). This is an important change to reduce the number of 502 situations. If you leave it on restart it will still occur. It will not occur every time you make a change to the configuration, but once the restart interval expires, it will occur. This is not the case when you set a an interval and choose graceful restarts instead of restarts. An interval in that case should be at least 360 seconds, better more.
