如何在php中将json对象转换为数组？

Question

I have this JSON

[size: null, color: "white"]

Which send to the server via post method.

I try

$your_json_string = json_decode($your_json_string, TRUE)

and

$your_json_string = html_entity_decode($your_json_string);
$your_json_string = json_decode($your_json_string, true);

• With print_r($your_json_string); I get: null .
• With echo json_last_error(); I get: 4 .

Any ideas on how I can solve this?

Answer 1

1) that is a json array [] not an object {}. 2) it will want property names quoted.

$String = <<< LOL
{"size": null, "color": "white"}
LOL;

print_r(json_decode($String,TRUE));

then you get

Array
(
    [size] =>
    [color] => white
)

Answer 2

If you have a wrong json string and you don't know how it will convert json to array in php. Example Below:

$string = '{test ing,test ingredients,test ingredients3,test ingredients4,test ingredients5}';

Trim your json string and remove non required data.

    $string = ltrim($string, '{');
    $string = rtrim($string, '}');

Remove comma from string and get normal php array

    $newSting = explode(',', $string);

Now you can loop through your data

foreach ($newSting as $key => $value) {
        echo $value;
    }
