PHP New Line Help

Question

I'm just starting PHP programming as you can tell. I want the results of each statement to be on their own line but can't get it to work yet. I tried referring to the code on this page and am obvsiously doing something wrong. Thank you very much.

<?
$mySentence="This is a sentence 123456789.";
$myNumber1 = 9.5;
$myNumber2 = .5;
$sum = $myNumber1 + $myNumber2;

echo "Hello, lets display our PHP variables: \r";
echo $mySentence;
echo "The sum of $myNumber 1 and $myNumber2 = $sum ";
echo "\"This text has double quotes\"";

?>

Answer 1

Try using \n instead of \r on the first line and in the rest you'll have to add \n at the end as:

echo "Hello, lets display our PHP variables: \n";
echo $mySentence."\n";
echo "The sum of $myNumber 1 and $myNumber2 = $sum\n"
echo "\"This text has double quotes\"\n";

If you want these to be echoed in a HTML page on separate lines you'll have to use the line break tag <br /> in place of \n

Answer 2

"\n"

is ascii new line code

if you want to see the line break on html you should use

<br />

like this:

<?php

echo "Hello world! <br />";
echo "I'm Gabriel";
?>

Answer 3

Use HTTP header to do this.

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

This allows plain text to be displayed correctly.

Also, echo the <pre> tag or use the PHP function nl2br, they both work.

For example:

<?php echo "<pre>line 1\nline 2</pre>"; ?>

or

<?php echo nl2br("line 1\nline 2"); ?>
