Front End Web Development Techdegree Student 21,661 Pointswhy is $this->instructions[] = $string?
This video is a little hard to understand, at video time 2:00, Alena create a function addInstruction and set its inner body as following php $this->instructions[] = $string , i am finding hard to understand that if instructions is a array then why put php $string in front of it. Is she assigning a override of array to a single value which is string? also i am unable to understand $tags involvement in the video

Front End Web Development Techdegree Student 21,661 PointsSeth Kroger why are they using addTag, is it a setter or getter as i remember it, when setting getters and setters we need to use the word
php setandphp get`Seth Kroger
