Question

I notice that every time I print_r some array, I can’t get the display style correctly, I mean it displays in just one line on the browser client view. Have you any tools, methods or any ways that can help display it better in a readable format ?

Answer 1

echo'<pre>';
print_r();
echo'</pre>';

or, if you don’t have anything else to output:

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