How to programmatically hide a block on another page in php (drupal)?

Question

PHP

Hello!
Can you please tell me how to programmatically hide one output block on one of the pages? I am using Drupal.
That is, I have this block registered in page.tpl.php and it is displayed on all pages as it should. But one needs to be removed. How to do it? firstly I work with both Drupal and c php

Answer 1

In the block settings, you can specify on which pages it should not be displayed without PHP.
PS And what about Smarty?)

Answer 2

Why did you need to write a block in page.tpl.php? Create a block in the admin panel and set visibility there. And in the template you can add your region and display it there.
