Why is my PHP file writing `\n` as a string instead of new lines?

Line Feed Issues in PHP File Writing

When writing data to a file in PHP, it is essential to correctly handle line feed characters to ensure desirable results. Encountering unforeseen issues with line feed representation can be frustrating.

In this case, the code provided is writing 'n' as a string instead of creating new lines in the output file. To resolve this, replace the usage of 'n' with "n" instead. The reason for this is that when using single quotes ('') for the string, the escape sequence 'n' is not recognized. Therefore, the literal string 'n' is written to the file instead of a line feed character.

Regarding the use of "rn" versus "n" for line feeds, it is important to note that different operating systems have different conventions. Windows systems typically use "rn" (carriage return followed by a newline), while UNIX-based systems use "n" alone.

To ensure portability and cross-platform compatibility, it is recommended to use "n" for line feeds and open the file in binary mode (using "wb" instead of "w" in the fopen function). This approach will prevent potential issues with line ending conversions and ensure consistent line breaks across different systems.
