I am using eclipse and Dreamweaver and i have about 650 php files and would like to replace a string in all files without opening individual files. Could you guys Please help me that, is available any function in eclipse or Dreamweaver so that i can replace the string with specified string to all files ?

There is also sub folders hierarchy.

Any help or suggestion will be highly appreciated.

In Eclipse, go to the Search menu, choose File..., enter the string to search and *.php in the file name pattern, then click the Replace... button.

You may also click the Search button, and then right-click in the Search view and choose Replace All... or Replace selected...

In Dreamweaver, CTRL+F (or Edit > Find (and replace)) then choose whatever you want from "Find in:" dropdown menu. You have:
