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

There are several functions to read and write a file.

You can read the file’s content with file_get_contents, perform the replace with str_replace and put the modified data back with file_put_contents:

file_put_contents($file, str_replace("\nH", "H", file_get_contents($file)));
