Tag {var} [RU] Tag {var}
============== =========
Тег {var} предназначен для создания переменных в шаблонах. The tag {var} is used for assigning template variables during the execution of a template.

К названию новой переменной предъявляются те же требования, что и к [именам переменных](http://www.php.net/manual/en/language.variables.basics.php) в PHP. Variable names follow the same rules as other labels in PHP.
Выражение EXPR подразумевает любое поддерживаемое выражение. A valid variable name starts with a letter or underscore, followed by any number of letters, numbers, or underscores.

{var $v = 5} {var $v = 5}
