Template directive: PHP Braces

This php smart braces {{: }} is a much concise directive that is an alternative to the @php: and @php; directive. Unlike the placeholder directive {{ }} which is used to display the content of a particular value, the php braces handles every item within it as a normal php code just as the @php: directive does. An example is shown below:
{{: }}
  {{: 

    $a = '123';
    $b = '456';

    echo( $a + $b ); //579

  }} 
                  
The sample above will be rendered just like a raw php code. The response is shown below:
  579
