Pretty-Printing JSON with PHP

Question

I\'m building a PHP script that feeds JSON data to another script. My script builds data into a large associative array, and then outputs the data using json_encode

Answer 1

The following is what worked for me:

Contents of test.php:

Testing JSON array output
  
  'apple', 'b'=>'banana', 'c'=>'catnip');
  // encode in json format 
  $data = json_encode($data);

  // json as single line
  echo "
Json as single line 
";
  echo $data;
  // json as an array, formatted nicely
  echo "
Json as multiline array 
";
  print_r(json_decode($data, true));
  ?>
  

output:

Testing JSON array output


Json as single line 
{"a":"apple","b":"banana","c":"catnip"}
Json as multiline array 
Array
(
    [a] => apple
    [b] => banana
    [c] => catnip
)

Also note the use of "pre" tag in html.

Hope that helps someone
