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

You could do it like below.

$array = array(
   "a" => "apple",
   "b" => "banana",
   "c" => "catnip"
);

foreach ($array as $a_key => $a_val) {
   $json .= "\"{$a_key}\" : \"{$a_val}\",\n";
}

header('Content-Type: application/json');
echo "{\n"  .rtrim($json, ",\n") . "\n}";

Above would output kind of like Facebook.

{
"a" : "apple",
"b" : "banana",
"c" : "catnip"
}
