How to access $ smarty variables from php code

Question

There is such a line

<input type="text" value="{$categoryID}" name="cat">

Is it possible to somehow access the $ categoryID variable from the php code?

UP

smarty.php

 $smarty->assign( "categoryID", $categoryID);

cat.html

 ... код и include файла smarty.php {php} $foo = $smarty->get_template_vars('$categoryID'); print_r($foo); {/php}

you in pkhp the code threw it there $smarty->assign('categoryID, $catId) .
Or do you want to extract and modify a previously added variable?

To get the values of previously assigned template variables in Smarty 3, use the getTemplateVars() method. When called without parameters, returns the entire array of assigned variables, and when specifying the variable name as a parameter, returns its value, respectively.

 <?php $smarty->assign('foo', 'bar'); $foo = $smarty->getTemplateVars('foo'); $all_tpl_vars = $smarty->getTemplateVars();

For earlier versions ( Smarty 2.x ) get_template_vars()

 $smarty = new Smarty; $smarty->assign('foo', 123); $foo = $smarty->get_template_vars('foo'); print_r($foo);

UPD

Since the question was revolved, the decision changes somewhat. The above code does not refer to the template, but php code. In the case of accessing a variable from a template inside the {php} tags, the code will be as follows:

 {php} print_r($this->get_template_vars('foo')) {/php}

Naturally, the work is already going on inside smarti itself, since what should be addressed to $this .

Well, in general, the tag {php} excluded from Smarty3, because do not interfere with logic and representation, for it is bad.

already tried $ foo = $ smarty-> get_template_var ('categoryID');
@sbaikov and where do you have underscores in the function name?
I tried it now $ foo = $ smarty-> getTemplateVars ('categoryID');
