Question from a newbie. The documentation says that
\r\nis an indication of the end of a line and a carriage return. Actually doesn’t work. I translate by
/br. What is
I asked about something else. The tutorial explicitly says:
<?php echo "1 \n"; echo "2"; ?>
But it doesn’t work in practice. Writes in one line. That’s what I didn’t understand. What’s the catch.

If all your code is written for output through “\r\n” (By the way, it’s better to use
PHP_EOLinstead, for cross-platform), then there is a wonderful function nl2br(), which will go through the line in which all the text generated by the page was written, and replace all line breaks with

If you want to break lines on the page that is being displayed, use
<br/>and there is also source code. The transfer there is carried out precisely by means of
\n. Source code is formatted for readability.
Take a look at the source codeof this page. All these transfers are made by means of
\nor by pressing
This code is in php
echo "1<br/>"; echo "2";
on the page and
in the file itself.
That’s the difference. I hope I understood your question correctly.

The newline result will be obtained when the text is output to a file or placed in
textarea. If you want to wrap text on the screen, use nl2br.
And in general, do not take the textbooks at their word. 😉

<br />is an HTML tag that tells the browser to display the content that follows it on a new line.
\r\n– normal line feed in text. There is also a cross-platform constant for line feed –
Line breaks in text are ignored by the browser (except in a few exceptions) and can only be seen if you open the page’s HTML code.

They said it was true about PHP_EOL, for example this code:

Look, I’m writing in the Clous9 console:
echo "\n"; echo "1: first_srt=1\nsecnd_srt=2\n"; echo "\n"; echo '2: first_srt=1\nsecnd_srt=2\n'; echo "\n"; echo "==============\n"; echo "\n";
1: first_srt=1 secnd_srt=2 2: first_srt=1\nsecnd_srt=2\n ==============
The difference between strings 1 and 2 is double and single quotes.

You need to put
headerat the beginning of the code
header("Content-Type: text/plain; charset=utf-8"); echo " ...\n"; echo " ...\n"; echo " ...\n";
