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.
