PHP - How to read message data without a key?

Question

This piece of jQuery codes is sent to one of our php pages.

var json = '{"object1":{"object2":[{"string1":val1,"string2":val2}]}}';
$.post("phppage", json, function(data) {
    alert(data);
});

Inside phppage, I need to do some processing depending on the message data. But I can not read these messages.

foreach ($_POST as $k => $v) {
    echo ' Key= ' . $k . ' Value= ' . $v;
}

Answer 1

What you need should work fine, but the JSON object turns into an array of arrays when it is provided to the given POST. You will get something like this:

["object1"]=>
  array(1) {
    ["object2"]=>
    array(1) {
      [0]=>
      array(2) {
        ["string1"]=>
        string(4) "val1"
        ["string2"]=>
        string(4) "val2"
      }
    }
  }
}

So object1 is an array that contains all the other data. If you do

foreach ($_POST as $key => $val) {
   echo $key . " > " . $val
}

"object1 > Array". , . , , , , , .

Answer 3

Step 1 (Javascript Code):

Instead:

$.post("phppage", json, function(data) {
    alert(data);
});

Do it:

$.post("phppage", 'json':json, function(data) {
    alert(data);
});

Step 2 (PHP code):

Change to:

$json=json_decode($_POST['json']);
foreach($json as $k => $v) {
  echo ' Key= ' . $k . ' Value= ' . $v;
}

or

$json=json_decode($_POST['json']);
print_r($json);
