PHP - How to Create a Newline Character

PHP - how to create a newline character?

Only double quoted strings interpret the escape sequences \r and \n as '0x0D' and '0x0A' respectively, so you want:

"\r\n"

Single quoted strings, on the other hand, only know the escape sequences \\ and \'.

So unless you concatenate the single quoted string with a line break generated elsewhere (e. g., using double quoted string "\r\n" or using chr function chr(0x0D).chr(0x0A)), the only other way to have a line break within a single quoted string is to literally type it with your editor:

$s = 'some text before the line break
some text after';

Make sure to check your editor for its line break settings if you require some specific character sequence (\r\n for example).

Print newline in PHP in single quotes

No, because single-quotes even inhibit hex code replacement.

echo 'Hello, world!' . "\xA";

newline character not converting to line break in php text area post

You need to use an actual linebreak in you <textarea>. \n wont work there.

nl2br converts linebreaks to html <br>.

With php-code you can add a linebreak like this:

<textarea name="comment" rows="5" cols="40">One line.<?= "\n" ?>Another line.</textarea>

Or you spimply write:

<textarea name="comment" rows="5" cols="40">One line.
Another line.</textarea>

If you want to reuse the submitted value:

<textarea name="comment" rows="5" cols="40"><?= htmlentities($_POST['comment']) ?></textarea>

Be careful here, you want to sanitize your user-input with htmlentities($_POST['comment']) or the user will be able to alter the page.

Additional info

<?= $var ?> is the short form of <?php echo $var; ?>

insert newline character into string in php as a delimiter

implode! Thank you @barmar for giving me the idea to send it as an array. I don't want to do that for the reasons mentioned above BUT I was able to build an array from the strings:

$textArray = array($_POST['top'], $_POST['foo'], $_POST['bottom']); 

then implode it with the newline char as the delimiter.

$text = implode("\n", $textArray); 

everything else worked as hoped in the other places throughout the code. Not sure why it wasn't working before without implode so if you've got any insights, i'm all ears. Thanks again @barmar

PHP: trying to create a new line with \n

Newlines in HTML are expressed through <br>, not through \n.

Using \n in PHP creates a newline in the source code, and HTML source code layout is unconnected to HTML screen layout.

Adding a \n newline symbol when using sprintf in PHP

The newline symbol \n will only being interpreted when it is enclosed in double quotes: ". Like that:

$line  = '...............';
$line .= "\n";

You should also know about PHP_EOL It is a constant that contains the systems newline delimiter which is different on several operating systems. For example it will be \n on Linux but \r\n on Windows. The most portable code would look like:

$line  = '.....';
$line .= PHP_EOL;

PHP new line character (\n) Not Working

This is the first thing you will learn if you are learning even from a PHP 5 For Dummies book. HTML doesn't respect new line or tab or multiple space characters. You have to use <br /> for new lines.

^{* Sourced from PHP 5 For Dummies by Janet Valade.}

Change your code to:

<?php
$firstName = 'David';
$lastName = "Powers";
$title = '"The Hitchhiker\'s Guide to the Galaxy"';
$author = 'Douglas Adams';
$answer = 42;
$newLines = "<br /><br />";

$fullName = "$firstName $lastName |";
$book = "$title by $author";

$message = "Name: $fullName $newLines";
$message .= "Book: $book <br /><br />";
$message .= "Answer: $answer";

echo $message;
echo "Line 1<br />Line 2";

If you are just opting for a text based layout, you can set the header to the browser to respect it as just a text file. For that, you need:

header("Content-type: text/plain");

This will render without any HTML.

New line character php

This will surely work.

foreach($result as $row){
    $node =  '{"author":"' . $row["name"] . '"},';
    echo "<br>";
}

New line (\n) in PHP is not working

When you run a PHP script in a browser, it will be rendered as HTML by default. If the books you’re using show otherwise, then either the code or the illustration is inaccurate. You can use “view source” to view what was sent to the browser and you’ll see that your line feeds are present.

<?php
echo "Line 1\nLine 2";
?>

This will render in your browser as:

Line 1 Line 2

If you need to send plain text to your browser, you can use something like:

<?php
header('Content-type: text/plain');
echo "Line 1\nLine 2";
?>

This will output:

Line 1
Line 2

PHP Linefeeds (\n) Not Working is referring to sending output to a file rather than the browser.
