Tutorial: php functions and elementary problems-php Tutorial

For advice, I have just been involved in php functions and elementary problems, so I am a newbie here, so I am asking for advice. I am still reading books about php,
I have some questions about the following code:

The latest 10 investment records of this project

{$ Vi. user_name | hidecard ###, 4}
        
{$ Vi. transfer_num}
        
{$ Vi. investor_capital | Fmoney =###} RMB
        
{$ Vo. borrow_interest_rate} %/year
        
{$ Vi. transfer_month} months

Code, It should contain the content for reading the database. I do not know whether it is correct or not, but it is usually stored somewhere. I did not find it on this file page,
In the {$ vi. investor_capital | Fmoney =###} sentence, $ vi. investor_capital is the read field? Fmoney #### is it a function? I don't know if this understanding is correct. what does it mean?

Reply to discussion (solution)

You are a template, not a php code

This is a page template. what kind of page template do you use?
The data is transmitted from the php background.

This is a template, not the field read by $ vi. investor_capital | Fmoney =###} in the above sentence of php code {$ vi. investor_capital? Fmoney #### is it a function? I don't know if this understanding is correct. what does it mean?

Read the development instructions carefully.

I already told you: this is not a php syntax.
