"\n" not working, arrays not displaying properly...

[rxgvhqkrywq6cxdjoar]

Hey everyone,

 

PHP is not co-operating today!

I'm having issues creating new lines...

 

This is my code:

 

<?php
$a = array ('a' => 'apple', 'b' => 'banana', 'c' => array ('x', 'y', 'z'));
print_r ($a);
echo "first line". "\n";
echo "second line\n";
echo "third line \n";
echo "...";
?>

 

The expected output is:

 

Array
(
    [a] => apple
    [b] => banana
    [c] => Array
        (
            [0] => x
            [1] => y
            [2] => z
        )
)
first line
second line
third line
...

 

The actual output is:

 

Array ( [a] => apple [b] => banana [c] => Array ( [0] => x [1] => y [2] => z ) ) first line second line third line ...

 

Which is hardly readable when using large arrays!

Any help us much appreciated 

 

Thanks in advance!

If you view the source of the output you'll see it is as expected. You're looking for HTML <br /> line breaks. If you want the print_r to display the line breaks in html as well, use the second parameter in print_r to return the output and then perform nl2br on that to convert character \n to <br />.

 

echo nl2br(print_r($a, true));

or:

<?php 
echo '<pre>';
print_r($some_array);
exit('printed nicely as source me');
?>

 

or you can create your own print function to reuse it elsewhere.

You need to read up on content types. If you send data as text/html to a web browser, it'll regard it as HTML. In HTML, consecutive whitespace is ignored. For example, a billion space characters would still only be represented as a single space.

freakstyle, you are a saint.

thank you so much!

As Daniel said, send the output as plain text rather than HTML and you won't have to play around with writing HTML tags to show the text in a monospace font.  Use something like the following, before your print_r:

 

header('Content-Type: text/plain; charset=utf-8');

 

 

Edit: Can't speel correctely!!

salathe another great solution that solves my problem.

thanks all.

LOL, it wasn't my solution. Thank Daniel.

 

[ot]Do you only read code, rather than taking notice of all those other less-colourful words? Not a jab, just an observation.[/ot]

I had no idea what Daniel was referring to until you enlightened me.

Thanks all.

 

Over and Out.
