Errors with json_decode in php

Question

We are have json:

{ "list":
 [
 {"id":"4045","value":"Xin Kai"},
 {"id":"4141","value":"YZK"},
 {"id":"4099","value":"ZX"}
 ]
}

For get value we use next code:

$json = json_decode($result, true);
foreach($json['list'] as $item) {
 print $item['value'].'<br />';
}

But now we get error: Warning: Invalid argument supplied for foreach()...

Tell me please where error in code and how will be right?

• Darren: @learner what do you get in that var_dump($result)? The full string. because as your example sits, it works: eval.in/208543
• zerkms: ideone.com/zzoQHd - it works
• user2881809: @zerkms in your code { "list":[{{ instead of { "list":[{
• zerkms: That string has broken UTF characters. JSON string must be a valid UTF string. But even that string does work fine (on php 5.3)
• user2881809: @zerkms i see it, me need delete this or other action?

Answer 1

Your issue is that you're doing this in your code:

foreach($json->list as $item) {

When you should be doing this:

foreach($json['list'] as $item) {

As you decoded it as an array and not as an object.

Also, as zerkms said,

^{>>> windows-1251 <<< JSON document must be in UTF-8}

Answer 2

Before json_decode you need get json in utf-8, in you exmple(if you get json in windows-1251) you need use next code:

EXAMPLE FIRST - if you want get array

//if you want get array
$json_obj = json_decode(iconv("windows-1251","utf-8",$result), true);
foreach($json_obj['list'] as $item) {
 print $item['value'].'<br />'; 
}

EXAMPLE SECOND - if you wnt get object

//if you wnt get object
$json_obj = json_decode(iconv("windows-1251","utf-8",$result));
foreach($json_obj->list as $item) {
 print $item->value.'<br />'; 
}

Enjoy!
