note 85841 added to class.dir

I wanted to know if you have a function to replace (or add) text to the beginning of all files (with certain extension) including sub-directories? In other words, write something to every file this level and below. reason... I want to add javascript header code (also a footer) to a lot of php files. Hmmm... guess I need to write something else (footer) to end of file also? ---- Server IP: 209.41.74.194 Probable Submitter: 208.85.12.252 ---- Manual Page -- http://www.php.net/manual/en/class.dir.php Edit -- https://master.php.net/note/edit/85841 Del: integrated -- https://master.php.net/note/delete/85841/integrated Del: useless -- https://master.php.net/note/delete/85841/useless Del: bad code -- https://master.php.net/note/delete/85841/bad+code Del: spam -- https://master.php.net/note/delete/85841/spam Del: non-english -- https://master.php.net/note/delete/85841/non-english Del: in docs -- https://master.php.net/note/delete/85841/in+docs Del: other reasons-- https://master.php.net/note/delete/85841 Reject -- https://master.php.net/note/reject/85841 Search -- https://master.php.net/manage/user-notes.php
