That's what a stack trace does. It shows you the chain of events that lead to your error (and can provide details like class, line number, etc)
PHP spl_autoload: how to determine the autoload function requestor

Question
Is there a way for the function registered by spl_autoload_register to know the source file/class/method that's calling it? I want to be able to output a useful error when a class is not found so I know which source file needs to be updated. For example:
spl_autoload_register(function($className)
{
$classFile = 'include/' . $className . '.php';
if (!is_readable($classFile))
{
echo 'Could not load ' . $className . ' requested by ' . $source;
// how to figure out $source -----------------------------^^
return false;
}
include $classFile;
return false;
}
Solution
OTHER TIPS
Try var dumping debug_backtrace()
to see the array it returns and if it can helps.
spl_autoload_register(function($className)
{
var_dump(debug_backtrace());
