In PHP, a callback function is used to pass a reference to a function as an argument to another function. This allows the receiving function to call back or execute the passed function at a later time, typically to handle events or customize behavior dynamically.
PHP callbacks are functions that PHP can use to call them dynamically. Native functions such as array map, usort, preg replace callback, and others use them. A callback function is a function that you write and then provide as a parameter to another function. Once the receiving function has access to your callback function, it can use it whenever it wants.
