Function call error? Let's take a look at the tutorial.

See what the template tag is.

How is your template hello.html Supposed To Be php?

Check whether execution is performed.helloMethod.
You should read the template directly.
You paste your access URL.

Check whether the configuration file has any settings.TMPL_L_DELIMIn this case, it is generally a matter of delimiters, causing the template engine to not parse variables.

I didn't see any problems.

The default template tag is <$ name>.

You need to take a look at your project configuration file to see your template selection. If it is not set to smarty, the default template is Think, which uses <$ name> for output.
