Difference between extension and library in PHP

0

In PHP there are some extensions within the language, basically they are sets of classes. For example, PHAR is one of these extensions. Basically, my question is this:

  • What's the difference of an extension to a library?
  • Would it be correct to call them libraries because they are a set of classes?
