如何从json中提取字符串

I have to extract strings from a xml file. One particular value has been generated using json enconding. Here is a exemple of what I can find:

<plus_details>
[["Neuf"],["Petite copropri\u00e9t\u00e9"],["Vue mer"]]
</plus_details>

I would like to extract the strings and display them inline and separated by commas, like this :

Neuf, Petite copropriété, Vue mer

I tried using json_decode function, but the only thing I can display is:

array(3) {
[0]=>
array(1) {
[0]=>
string(4) “Neuf”
}
[1]=>
array(1) {
[0]=>
string(20) “Petite copropriété”
}
[2]=>
array(1) {
[0]=>
string(7) “Vue mer”
}
}

Any help would be appreciated. Thanks.

    Simple use a loop to go through your data. When you json_decode the string you provided us, you will end-up with an array like this :

    Array
    (
        [0] => Array
            (
                [0] => Neuf
            )
    
        [1] => Array
            (
                [0] => Petite copropriété
            )
    
        [2] => Array
            (
                [0] => Vue mer
            )
    
    )
    

    So in order to get your data you need to loop your array.

    foreach(json_decode($json) as $data){
        echo $data[0];
        echo '<br>';
    }
    

    The output of the above code is:

    Neuf
    Petite copropriété
    Vue mer
