用于修改值的循环数组（JavaScript到PHP并返回JavaScript）

Question

I'm working with JavaScript and PHP using arrays, the first step is create the array, here

var ListaA=[];
var i = 0, len = options.length;
while (i < len){
            var tmp = {
                        'proyecto':'test',
                        'pendientes1':0,
                        'pendientes2':0,
                        'terminadas1':0,
                        'terminadas2':0,
                        'solucion':0
                };
                ListaA.push(tmp);
                i++;
            }

Then i send it to my PHP file like this

var laLista = JSON.stringify(ListaA);

$.get("php/operation.php?test="+ {'test' : laLista }, function( data ){
                var tmp = {
                        'proyecto':""+value['proyecto']+"",
                        'pendientes1':""+value['pendientes1']+"",
                        'pendientes2':""+value['pendientes2']+"",
                        'terminadas1':""+value['terminadas1']+"",
                        'terminadas2':""+value['terminadas2']+"",
                        'solucion':""+value['solucion']+""
                    };
                    ListaA.push(tmp);
            });

As you can see above i have ready the code to get the data which represents the array sent by the PHP file, so i got covered that part, my issue here is in my PHP file, here.

$arrayWork = json_decode($_POST['test']);

Then i want to loop, this time, just for testing i'm just taking one of the values and incresing it to watch the result, like this

foreach($arrayWork as $value){
     $value['pendientes1']++; // this is not working for me
}

I got the following: "invalid argument supplied in foreach". So, what's wrong with my code? and which is the properly way to loop it and return it to my JavaScript?

I hope you can help me out with this issue. Thank you for your time and attention, good night.

Using this code

$arrayWork = json_decode($_POST['test']);

your json isn't really converted into an associated array, look at below

mixed json_decode ( string $json [, bool $assoc = false [, int $depth = 512 [, int $options = 0 ]]] )

assoc When TRUE, returned objects will be converted into associative arrays.

To convert json object into an array just add true to the second parameter to it

$arrayWork = json_decode($_POST['test'], true);**strong text**

To increment an index value in an array

foreach($arrayWork $key => as $value){
    $arrayWork['pendientes1']++;
}

Edited.

also since you are using $_POST method change your ajax from $.get to $.post

$.post("php/operation.php?test="+ {'test' : laLista }, function( data ){
      var result = JSON.parse(data); // parse json string into json object
       ...
    });
