adding newline in php

[nokmaster]

hi,

in php how to add a newline?

for example:

echo "Test1";
echo "Test2;

Result should be look like this:

Test1
Test2

but isnt working

Echo just outputs what you put between the quotes. If you try:

// two lines
echo "Test
test1";

// a new line in linux
echo "test1\ntest2";

// a new line in windows
echo "test1\r\ntest2";

// a new line in MAC
echo "text1\rtest2";

// a new line in XHTML
// test1<br />test2

// a new line in html
// test1<br />test2

Strictly speaking, that's XHTML (and even more strictly speaking, only in XML parsing mode, although no-one seriously observes that).

In HTML a new line is simply <br>.

I edited my post. I always observe that in XHTML.

Slightly bad wording by me. I meant that no-one really observes the difference between XHTML in XML parsing mode and in text/html mode; most people send XHTML in text/html mode anyway. So rather than <br> in XML mode you will almost always see <br /> in text/html mode; which is fine since no real-world user agents care anyway.

And IE6 doesn't recognise application/xhtml+xml MIME type.

Nor 7, which makes properly handling XHTML more or less a giant pain in the arse.

Doesnt the \n just do a simple new line?

It represents a newline character, yes, but whether a newline is actually a line break depends on the platform. On Unix/Linux it is all that is required. On Windows, most applications recognise it as a line break, but some require \r\n. And on older Mac platforms only \r is required although \r\n will function as well. Newer Mac platforms, I believe, use only \n, since they're now based on Unix.


This all applies to text-only response bodies of course. If you are using HTML or XML then formatting your response body nicely is generally over the top.

Thanks for the details.

So then when I format my dynamic code to be correctly indented when a user "view source" is over the top

Definitely, unless you are caching the results and subsequently simply serving from the cache.

You dont say why you are asking, so just saying for incase this help:

I store breaks as new line chars, then if i want to display it on a page, i use the build in nl2br function

by the way....there's no <br> in xhtml...it's <br />!!!!!!!
