What is the Closures?
Let’s define firstly what is the anonymous function? If you are a front-end developer and have worked with JavaScript, you should be already familiar with anonymous functions. These pretty useful to write short inline functions, define callback etc.
An anonymous function is a function that was declared without any named identifier to refer to it. Here is the PHP implementation of anonymous function:
<?php $anonymousfunctionReference = function(){ echo "Anonymous function called" }; echo $anonymousfunctionReference();
