Php للبحث عن نص معين داخل عدة ملفات

السلام عليكم,

كان عندى شوية وقت فاضى فكتبت كلاس صغير, طبعا انا ملحقتش احط كل امكانيات grep فى الكلاس دة حاليا, هو دلوقتى كل الى بيعمله هو recursive search على المجلدات و الملفات الى انت بتحددهاله.

ملحوظة: الكود دة php 5 , و حتلاقى الـ DirectoryIterator فى SPL .

مثال استخدام

$searcher = new SearchFile('/media/hda2/server/c/lexical analyzer', true);

var_dump($searcher->find('void'));
