Typed correctly, they are escape sequences that correspond to one ASCII character each\t = tab\r = carriage return\n = linefeed ("newline")To be interpreted correctly by PHP they must be placed in "double" quote marks.They do not print out as HTML, so they are invisible in browser view. You should see tabs and line breaks correctly if you View Source.

FWIW, the online manual has some explanation here: http://php.net/manual/en/language.types.string.php . Scroll down a bit.

Stay calm... you can find more information about them in the PHP manual here.

Thank you...Thank you thank you thank you.

Different operating system families have different line-ending conventions. When you write a text file and want to insert a line break, you need to use the correct line-ending character(s) for your operating system.Unix based systems use \n as the line ending characterMacintosh based systems use \r as the line ending characterWindows based systems use \r\n as the line ending charactersYou may like to check out the note under the $mode parameter of the fopen() function for more information about the use of these characters in PHP.Roddy

I Add and remove them to my code and they do NOTHING

They do nothing? You mean all this time, when all of these people have been using them, they haven't actually been doing anything? Maybe you should let everyone know.

I can't Google Them

Maybe you're just not trying hard enough:http://www.google.com/search?q=%22%5Cn%22+php

BUT I SEE PEOPLE USING THEM

Well, why didn't you just ask someone what they were? You would have heard the term "escape sequence", then you could have looked that up:http://www.google.com/search?q=escape+sequence

I SEE PEOPLE HAVING PROBLEMS WITH IT IN PHP 5.3

THAT'S BECAUSE NO ONE BOTHERS TO LEARN HOW ANYTHING WORKS BEFORE THEY USE IT.

ITS NOT EVEN IN THE PHP MANUAL (or if they are... They can't be searched because THEYRE ONE RECOGNIZABLE CHARACTER LONG!

Instead of searching through the manual, just start at the beginning and read until the end. If you're trying to write PHP code and you haven't read through or even glanced at the "Language Reference", "Security", and "Features" sections in the manual, then you're wasting your time (and the time of those you yell at online):http://www.php.net/manual/en/index.phpThe part you're looking for is in the Types section, only the second section in the Language Reference. It wouldn't kill you to read through it at least once.

JSG, you really need to get in touch with your inner self. You're so laid back, who can even tell what you mean? Let some emotion shine through, man!

I'm going to channel my inner Glenn Beck, where I start crying before explaining that "I just love this internet".
