How to get PHP to support short tags

How do I make PHP files support short tags? But look at this problem, most of the PHP development may feel very simple, not just to change the php.ini in Short_open_tag = off to Short_open_tag = on? But today I'm having a problem.

I'm using Wamp's integrated environment, and I just started setting Short_open_tag to on in PHP's php.ini files, but I still can't use a short label. Here's my workaround: First output phpinfo (), view the directory of the loaded configuration file, and see if the profile you loaded is consistent with the path you modified. After you change it, remember to restart Apache.
