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:

• Selected Text
• Current Document
• Open Documents
• Folder...
• Selected Files in Site
• Entire Current Local Site

For eclipse, check this: Search for all files in project containing the text 'querystring' in Eclipse
