json无法显示为php数组

Question

The examples I checked seems simple but I can't figure it out what I'm doing wrong. I'm trying to convert and display JSON text as object array in PHP.

$json = '{"color1":red, "color2":blue, "color3":yellow}';
    $arr= json_decode($json, true);
    print_r($arr);

It doesn't output anything. but when I print $json, the output is just fine

Answer 1

Well that's not json, try

$json = '{"color1":"red", "color2":"blue", "color3":"yellow"}';
$arr= json_decode($json, true);
print_r($arr);

notice the strings are quoted with ", also see http://json.org
