PHP has multiple functions to handle files operations like read, write, create or delete a file or file contents.

1. file_put_contents():It is used to create a new file.

Syntax :

file_put_contents(file_name, contentstring, flag)

If file_name doesn't exist, the file is created with the contentstring content. Else, the existing file is override, unless the FILE_APPEND flag is set.

2. file_get_contents(): It is used to read the contents of a text file.
