Javascript将我的嵌套数组视为对象

Question

I'm trying to send a nested PHP array to Javascript. But Javascript parses the top level as an object.

The Teams array should contain 2 other arrays with each 2 team names

As you can see in the screenshot and the json, the "Teams" is an object.

"teams":{"1":["test","test"],"2":["test","test"]},"results":[]}

This is the code I'm using to build up the nested array

$iterator = 0;
for($i = 0; $i < $competition->teams->count(); $i++) {
    if($i % 2 == 0) {
        $iterator++;
    }
    $data["teams"][$iterator][] = "test";
}

The funny thing is, it is working when the array is not multidimensional. For example the following example doesn't return Teams as an object.

I'm guessing if I remove the array keys it might work, but It's impossible to have a nested array without array keys, right?

Any idea what I might be doing wrong? And how I can get Javascript to just see my nested array without seeing it as an object.

Thank you!

There is one problem with your code, $iterator always starts with value 1 so json_encode function uses JSON object to preserve that index.

Everything changes when you start indexing your array from 0 instead.

$test = array(
    1 => 'test'
);

echo json_encode($test);

Shows {"1":"test"} which is an object.

$test = array(
    0 => 'test'
);

echo json_encode($test);

Shows ["test"] which is an array.
