Today, I spent two hours configuring the environment for a colleague. I didn't find the problem. I just loaded a file and didn't run it. my colleague told me about the problem of short labels, it was discovered later that it was caused by short tags .??? In php. ini, enable the short label control parameter: short_open_tag = On. if it is set to Off, the php file like this format cannot be parsed normally: phpinfo ()?> But only parse To support short tags in php, we need to set short_open_tag to On.
