How Can You Determine the Location of a Function's Definition in PHP?

Finding the Definition of a Function

Determining the location of a function's definition can be crucial for debugging or understanding the codebase. In PHP, there are several approaches to achieve this.

One method is to use the ReflectionFunction class:

$reflFunc = new ReflectionFunction('function_name');
print $reflFunc->getFileName() . ':' . $reflFunc->getStartLine();

This code snippet creates a ReflectionFunction object for the specified function and retrieves its source file and the starting line number, which represent its definition.
