How to add php code to Joomla?

Question

PHP

There is such a Joomla
hostingkartinok.com/show-image.php?id=318b12c7dbb0...
I need to generate a date
I write:
2015 - <?php echo(date("Y"));?>
and nothing.
Why?

Answer 1

This thing needs to be implemented through /templates/your_template/index.php (or any other php).
If you really want to use the module/material editor, then you need a plugin.

In the material it will look something like this.
2015 - {source}<?php echo(date("Y"));?>{/source}
