Find and replace in a file

Question

I want to replace certain strings with another one in a text file (ex: \\nH with ,H). Is there any way to that using PHP?

Answer 1

If you're on a Unix machine, you could also use sed via php's program execution functions.

Thus, you do not have to pipe all of the file's content through php and can use regular expressions. Could be faster.

If you're not into reading manpages, you can find an overview on Wikipedia.
