Trace where code is coming from (PHP)

Question

I\'m going through a customer\'s server, running crazy proprietary forum software (vBulletin) and even worse SEO mods (vbseo). I cannot figure out where the php code for a page

Answer 1

To trace the origin of a specific function, you can do this:

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

See How to find out where a function is defined?

To trace the origin of a specific class, you can do this:

$reflClass = new ReflectionClass('class_name');
print $reflClass->getFileName() . ':' . $reflClass->getStartLine();

To get a list of all the includes that went into making a page, you can do this:

var_dump(get_included_files());

To get a list of all the functions that are defined on a page, you can do this:

var_dump(get_defined_functions());

To get a list of all the user-defined functions on a page, you can do this:

$defined_functions = get_defined_functions();
var_dump($defined_functions["user"]);
