To complete the request, one example (if you are not familiar with
other generators or languages):

1. include 'somfile.php'      
2.
        #line 1 "linedirective.php"
4.  class Foo                 // treated as line 1
5.  {                         // treated as line 2
6.   var $prop1;              // treated as line 3
7.                            // treated as line 4
8.   function bar ($args)     // treated as line 5
9.   {                        // treated as line 6
10.   Some invalid syntax;    // treated as line 7
11.   return;                 // treated as line 8
... 

Even if the syntax error happens on line 10 of this file, it will be
reported on line 7 of the file "linedirective.php". Not sure if it will
work exactly like that in php, but this is how it works in c# for
example.

I would love to have it in 5.x :)

Cheers,
