Question

How can I print an array so instead of being all a single line such as:

Array ( [0] => Array ( [Palabra] => correr [Tipo] => Verbo ) [1] => Array ( [Palabra] => es [Tipo] => Verbo [PersonaSujeto] => tercera [CantidadSujeto] => singular [Tiempo] => presente ) 

It displays something more readable like this or similar:

Array ( 
    [0] => Array ( 
        [Palabra] => correr
        [1] => Array ( 
             [Tipo] => Verbo 
             [Tiempo] => Infinitivo) )
    [1] => Array ( 
        [Palabra] => es 
        [Tipo] => Verbo 
        [PersonaSujeto] => tercera 
        [CantidadSujeto] => singular 
        [Tiempo] => presente ) 

Answer 1

It is printed out with a line break, but in HTML line breaks are meaningless. You can do one of 2 things:

1. Tell the browser it’s not an HTML document, but a text, by placing the following code before any output is sent:

   header('Content-type: text/plain');
   

2. Simply have <pre> tags around the printed array:

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