print values of a nested array php

Question

First let me say that I have gone through a lot of related question on here but none of them solve my issue. I have and php nested array in db and need to print the all the values. the output prints out the first top most array (which is the 'name', and values "Office , home") but does not get the nested array values which is contained in 'BB". this is my code:

function getTB($name='', $value='') {
$value    = json_decode($value);

$name = '';  $BB= ''; 
foreach ($value  as $key=>$val) {
    $name .= $val['name'].',';

JSON code:

[{"name":"Office","TB":[{"date":[false,true],"time":"8:00 AM"}]},{{"days":[false,true],"time":"6:00 PM"},

Are you printing the array out for debugging purposes? Perhaps print_r or var_dump may be of use (uk3.php.net/print_r uk3.php.net/var-dump) — Pudge601

no i need to print the information out in a doc which will be used later by a different program — user3581872

Okay, so can you not just re-encode it in JSON format with json_encode? — Pudge601

@Pudge601 I do not understand your suggestion. My problem is that am unable to print out the entire array not with the format — user3581872

use array_walk_recursive

for example if you have json like this (which is having a subarray)

$decoded = json_decode('{"abc": "one",
                         "def": "two",
                         "sub_array": {
                                 "ABC": "ONE"
                                 }}', true);

array_walk_recursive($decoded, function($value,$key) {
  echo $key.' :'.$value.'<br>';
});

the output will be

abc :one
def :two
ABC :ONE

so use like this instead of normal foreach

Update

use like this

$arr='[{"name":"Office","TB":[{"date":[false,true],"time":"8:00 AM"},{"days":[false,true],"time":"6:00 PM"}]}]';

$rr=json_decode($arr);

foreach ($rr[0]->TB as $key => $value) {
array_walk_recursive($value, function($k,$kk){
     echo 'Key is '.$kk.' & Value is '.$k.'<br>';   
});
}

output:

Key is 0 & Value is 

Key is 1 & Value is 1

Key is time & Value is 8:00 AM

Key is 0 & Value is 

Key is 1 & Value is 1

Key is time & Value is 6:00 PM

can you post the json code,with out decoding it..? which looks like {abc:adad...}

ɹɐqʞɐ zoɹǝɟ Over a year ago

you can access each subarray like this $rr[0]->TB[0] and $rr[0]->TB[1]
