Php and newlines: what do i need to know?

I have some questions about \r\n:

  • Does the new line depend on the browser? (and not how they are displayed in the browser, but how it <textarea>sends them to php via an HTTP request)
  • Are new lines system dependent? (where does php run)
  • will php apply implicit conversion?
  • Will mysql use implicit conversion?

Thanks in advance!

The system independent method uses the constant PHP_EOL.

New lines are browser independent, external tag with CSS white-space: pre you must execute the nl2br () php function to convert strings to BR tags.

It was a great success for me that in single quotes, 'like\nthis'escape sequences (for example, \n) would not be interpreted. You must use double quotes "like\nthis"to get the actual newline.
