php - Need some advice/suggestions on template syntax -

I have coded a small php template parser, so the template can be easily parsed, and within templates {variable_name} example

  & lt; Title & gt; {Title} & lt; / Title & gt;  

Can you suggest me if / else statement syntax?

I have thought of doing this:

  {if {logged_in}: TRUE} You are logged in ... {else} You are not ... {/ If}  

and ...

  {if {logged_in}: TRUE} You are logged in ... {/ if}  

Shows the above original if / other template syntax (it checks whether the variable is logged == true), but since I am doing more of a designer, I was thinking that I myself The input can be obtained (hence the designer can easily understand syntax without knowledge of server-side coding Es).

Cheers!

Sure.
Here is:

  & lt ;; If ($ logged_in):? & Gt; You are logged in ... & lt ;? Else:? & Gt; You are not ... & lt ;? Endif? & Gt;  

The best syntax ever
As you can see, the opening and closing tags have been slightly altered.
But nothing needs to be parsed altogether - just include this file!
BTW, your output

  & lt; Title & gt; & Lt ;? = $ Heading? & Gt; & Lt; / Title & gt;
