The only escape sequence you can use in single quotes is for the single quote itself.

New Lines (\n) and Single Quotes - PHP, No, not that I'm aware of :) you can try: <?php define('LF', "\n"); // or 'NL' or 'NewLine' or 'LineFeed' or echo 'first line', LF, 'second line'; the sequence of characters matching the regular expression is a Unicode codepoint, which will be output to the string as that codepoint's UTF-8 representation (added in PHP 7.0.0) As in single quoted string s, escaping any other character will result in the backslash being printed too.

- Ah ok.. I was hoping I wouldn't have to resort to that.. Thanks!
- yessir. He answered it in under 10 min. I had to wait till then to accept, then I forgot about it haha.

- That's not the right reasoning. It's no because in PHP you can not express a new-line character in single quotes. And that's it. Reading the manual could have helped :)
- @hakre Surely, reading the manual could have helped, but thankfully, StackOverflow is the place to conveniently look for exactly these answers ;)
- You should usually not use PHP_EOL as this makes your code dependent on the system it is running on. E.g. your Linux server is communicating with another server and then your server gets replaced by Windows... Not good.
- Unfortunately its more for terminal purposes.. thanks for your response though.
- Try this in a text-only email ;)
- It's not a fear.. you just get better performance when you use single quotes, so I try to use them more often then not.. but yah, this isn't really a great solution for this problem, its more trouble than its worth. Thanks.
