Question

当我使用

时，我正试图在php上打印一个数组

echo json_encode($array);

它告诉我这个：

{
    "1": {
        "x": "145",
        "y": "20"
    },
    "2": {
        "x": "145",
        "y": "40"
    }
}

但我想要这个：

{
    {
         "x":"145",
         "y":"20"
    },
    {
        "x":"145",
        "y":"40"
    }
}

怎么做？

Answer 1

只需使用array_values，如

echo json_encode(array_values($array));

Answer 2

为了达到这个目的，你需要像这样构建你的数组;

$arr = array();
$arr[] = array("x"=>145, "y"=>20);
$arr[] = array("x"=>145, "y"=>20);

或

[{"x":145,"y":20},{"x":145,"y":20}]

这将为您提供以下json_encode

$Articles =  DB::table('articles')->get();

//for test purpose here i can run a for-loop and print its values

foreach ($Articles as $Article) {
    echo "Article id : ".$Article->id";
    //here i cant print $Article->score
}

$Articles = $this->likesScoreFunction1($Articles);
$Articles = $this->scorefunction2($Articles);
$Articles = $this->scorefunction3($Articles);

Answer 3

$newArray = array();
foreach ($array as $key => $val)
{
    $newArray[] = $val;
}

print_r(json_encode($newArray));

**Result**: [{"x":"145","y":"20"},{"x":"145","y":"40"}]
