如何在php中解码json数组？

Question

lets say I have an json array like

{
    [
       {"id" : 1, "src" : src1, "name" : name1},
       {"id" : 2, "src" : src2, "name" : name2},
       {"id" : 3, "src" : src3, "name" : name3},
       {"id" : 4, "src" : src4, "name" : name4}
    ]
}

how should I decode this json array in php??

$project_info_json = $_POST['project_info_json'];

if (get_magic_quotes_gpc()) {
    $project_info_json =  stripslashes($_POST['project_info_json']);
}else {
    $project_info_json = $_POST['project_info_json'];
}
$project_info_array = json_decode($project_info_json, true);

I already tried json_decode method but it seems like $project_info_array has 0 element count. can anybody tell me what am I doing wrong?

Answer 1

i Think this is not valid JSON

JSON should be like

[
    {
        "id": 1,
        "src": "src1",
        "name": "name1"
    },
    {
        "id": 2,
        "src": "src2",
        "name": "name2"
    },
    {
        "id": 3,
        "src": "src3",
        "name": "name3"
    },
    {
        "id": 4,
        "src": "src4",
        "name": "name4"
    }
]

Validate Your JSON @ http://jsonlint.com/

Your outer object in json does not have a key where the internal list is stored in.

Also, your strings in json should be quoted. src1 , name1 are unquoted.
