How can I parse a JSON file with PHP? -

i tried parse json file using php. stuck now.

this content of json file:

{     "john": {         "status":"wait"     },     "jennifer": {         "status":"active"     },     "james": {         "status":"active",         "age":56,         "count":10,         "progress":0.0029857,         "bad":0     } } 

and have tried far:

<?php  $string = file_get_contents("/home/michael/test.json"); $json_a = json_decode($string, true);  echo $json_a['john'][status]; echo $json_a['jennifer'][status]; 

but because don't know names (like 'john', 'jennifer') , available keys , values (like 'age', 'count') beforehand, think need create foreach loop.

i appreciate example this.

to iterate on multidimensional array, can use recursivearrayiterator

$jsoniterator = new recursiveiteratoriterator(     new recursivearrayiterator(json_decode($json, true)),     recursiveiteratoriterator::self_first);  foreach ($jsoniterator $key => $val) {     if(is_array($val)) {         echo "$key:\n";     } else {         echo "$key => $val\n";     } } 

output:

john: status => wait jennifer: status => active james: status => active age => 56 count => 10 progress => 0.0029857 bad => 0
