Question

Well, I am abit confuse using these \r,\n,\t etc things. Because I read online (php.net), it seems like works, but i try it, here is my simple code:

<?php
    $str   = "My name is jingle \n\r";
    $str2  = "I am a boy";

    echo $str . $str2;
?>

But the outcome is “My name is jingle I am a boy”

Either I put the \r\n in the var or in the same line as echo, the outcome is the same. Anyone knows why?

Because you are outputting to a browser, you need to use a <br /> instead, otherwise wrap your output in <pre> tags.

Try:

<?php
    $str   = "My name is jingle <br />";
    $str2  = "I am a boy";

    echo $str . $str2;
?>

Or:

<?php
    $str   = "My name is jingle \n\r";
    $str2  = "I am a boy";

    echo '<pre>' .$str . $str2 . '</pre>';
?>

Browsers will not <pre>serve non-HTML formatting unless made explicit using <pre> – they are interested only in HTML.
