Searching and replacing

Hi guys

I need a little help. I am working on a project for a friend. The program works like this. There is a text file that looks like this:

Code:

---

1234 = ABCD

---

The user loads a php file in the program. The program searches the php file for terms that are on the left right of the equals sign. If it finds one then it is replaced with the term on the left side.

Any help would be appreciated.

What is replaced? Are you saying, if the right side of the equals sign contains something then replace the left side of the equals sign with the right side in the text file?

thanks for the quick response.

once the php file is loaded it searches the php file. what is looking for in the php file is any term that is located on the right side of the equal sign. the text file looks like this. And say that while searching it finds text 2 in the php file, if it does it will replace it with text 1

Code:

---

text 1 = text 2
text 3 = text 4

etc...
