Get Caller Function Name in PHP
In PHP, determining the name of the caller function within a given function can be crucial for debugging and tracing purposes. To retrieve this information, you can leverage the debug_backtrace function.

debug_backtrace offers a comprehensive trace of the call stack, aiding in identifying the caller function and its details. It provides an array of frames, with each frame representing a function call.
