Anonymous functions in PHP, also known as closures, are functions that do not have a name and can be assigned to a variable or passed as an argument to another function. They provide flexibility and the ability to create functions on the fly.
They can use variables from the external scope (closing).
$func = function($name) { echo "Hello $name"; };
Call the function:
$hello("Tom");
Anonymous functions provide a powerful tool for more flexible and elegant programming in PHP. They are widely used in various scenarios, such as processing arrays, events, asynchronous operations, and many others.
