[SOLVED] question about \n

[CyberShot]

I was looking at some of the things you could do with php and one of the things I have tried is \n.

 

used this way

 

while(list($key, $val) = each($myArray)){
echo "$key => $val\n";

 

I expect it to echo the values out on a newline but never does any time I use \n I have tried \r. What am I missing

[Gayner]

use break tag if \n doesnt work lol

[MatthewJ]

while(list($key, $val) = each($myArray)){
   echo $key." => ".$val."\n";

 

The \n has to be inside quotes... but yes, you could use

 

while(list($key, $val) = each($myArray)){
   echo $key." => ".$val."<br />";

 

as well

If you view the page source for the generated html, you'll find that it does insert the \n

The issue is that browsers don't display \n, same as they reduce all consecutive white spaces to a single space character. Instead, HTML uses the <br /> tag

 

You could use

echo "$key => $val<br />";[code=php:0]or PHP also provides a function to help you with this:[code=php:0]echo nl2br("$key => $val\n");

\n doesn't change the view that you see in the browser; the same way returns in html doesn't cause text to goto the next line. You'll see it on the next line if you goto view page source. Otherwise use <br  />.

well my issue is that I am going through the php documentation and it gives code like this

 

$fruit = array('a' => 'apple', 'b' => 'banana', 'c' => 'cranberry');

reset($fruit);
while (list($key, $val) = each($fruit)) {
    echo "$key => $val\n";
}

 

and then says that it will output

 

a => apple

b => banana

c => cranberry

 

 

but then it doesn't. So I am trying to figure out if most or all or just some of the info on the site is B.S
