special characters don't work (\n, \t, ...)

 

what is the problem 

 

<?php

$string = "Hello \nWorld";
echo $string;

?>

 

Output:

Hello World

 

Not:

Hello

World

It doesn't work because you're looking at it with a browser, which anticipates HTML.  \n is meaningless to a browser (at least, in terms of what it renders to the screen).  Your normal white space characters won't work.  Instead, use <br />, the HTML tag for a line break.

Alternatively, wrap the output inside <pre>...</pre> tags. Then tabs and newlines will be output as expected.

Note that your thread title fell into the classic trap of new programmers.  You said "special characters don't work."  That's not the problem.  The problem is "I don't see special characters when I expect to see them."  The problem is that you're viewing your output incorrectly (in a browser, rather than plain text), not anything to do with PHP.  Make sure you define the question properly, it may help you understand a way to fix it on your own.

KevinM1& Barand thank you. I understand the cause of the problem now.

 

ManiacDan you are right. I am not a native English speaker, so expect faults like this and I am sorry, it wasn't intended.

Dergam, I wasn't attempting to scold you.  The phrasing lead me to assume something about the way you were thinking about the problem.  If you were thinking incorrectly, it would be good for you to think a different way so you could easily solve the problems.

 

Good that you got it working, and keep at it!  you're welcome here.
