PHP pretty print json encode

Question

Possible Duplicate    Pretty-Printing JSON with PHP       I m working on a script that creates a JSON file  Right now I m just using json encode  PHP 5 2 x  to encode an array into JSON output  Then I print the returned value to a file and save it  Problem is that the client wants to be able to open these JSON files for readability  so I d like to add line breaks in and  pretty print  the JSON output  Any ideas on how to do this  My only other alternative that I can see is to not use json encode at all and just write the file contents manually and add in my own line breaks for each line   Here s what I get     product name   prod1   val1  1  val2  8    Here s what I want        product name   prod1      val1  1     val2  8     I suppose I could also just replace every comma with a command followed by a  n  and same for the brackets    Thoughts
