Question

I use a program call php easy calendar. Into that, there is a lot of php file, most of them good php or HTML. In some file, there is some variable written in bracket like [time] [date] and so on…. it output a perfect valid value nicely formatted…

because the content of the file that DO something are encrypted with ioncude (what a shame) i cannot learn how they do that… is it a php function or a template engine…

can you explain to me, how to get a echo of a variable by telling it’s name like [name]

please share the light !

---

maybe it’s a template system, because when i try to use php function, it just don do anything

as request here is the code in file modern.php

<!--head-->

Answer 1

Yes, that’s some sort of custom template feature.
It’s not any functionality that PHP ships with out of the box.

As for how to do that yourself, a very quick and dirty way are regular expressions:

$replacements = array('foo' => 'f00', 'bar' => 'b4r');
echo preg_replace_callback('/\[(\w+)\]/', function ($match) use ($replacements) {
    return $replacements[$match[1]];
}, $template);

It may be much simpler or much more complicated than this, there are infinite ways to do this.
