Problem printing PHP output on multiple lines

Question

I am newbie to PHP I have written the following program:

$address=array('[email protected]','[email protected]','[email protected]');

foreach($address as $value)
{
     echo "processing $value\n";
}

If you see I have \n in the echo statement but I am not getting the output on new line.

How can I get each output on a new line?

I don't see any code; I see only the closing PHP tag, nothing else. — avpaderno

If you are outputting this as HTML then you must of course use a HTML break  .

If you're working in a browser, you need to break lines with

Browsers ignore text formatting (line breaks, breaking spaces, etc) in HTML to allow for the markup to be formatted to be readable to humans (otherwise, giant paragraphs would have to be on one line, and all sorts of other messes). You can view blocks of text preformatted by wrapping them in the <pre> ... </pre> tags, or setting the CSS of an element to white-space: pre;

is valid XML if your're not using an XHTML doctype is fine

That depends on the doctype. In 4.01, the use of self closing tags is not valid AFAIK.

You need to print an HTML line break instead:

Since you are printing to a browser

\n will line break properly when you view the source, but not in the HTML display. As mentioned, you need to use the   node for HTML

You may want to wrap your output in a <pre> tag as your browser is expecting HTML and is just collapsing the whitespace. The pre tag will reflect the whitespace (\t \n etc);

Alternately you can use a break tag, or wrap the data in a block display element. (eg:  or <div>)

Remember, SO accepts some HTML as markup for formatting, always wrap it with backticks (`).
