Question

我有这种格式的数组。

Array
(
    [0] => Array
        (
            [0] => User Name
            [1] => User Email
            [2] => User Mobile
        )

    [1] => Array
        (
            [0] => Anjali
            [1] => anjali@gmail.com
            [2] => 9945587526
        )

)

我正在寻找一个json

{"1":"user name","2":"user email","3":"user mobile"}

Answer 1

您正在寻找json_encode

返回包含值的JSON表示的字符串。

echo json_encode($array);

php＆gt;中也提供了json_encode {} 5.2.0

你也可以试试这个：

$json = array2json($data);

另请注意，JSON中的Array只是索引数组，而PHP Associatives数组是JSON中的对象

Answer 2

您需要json_encode，但要包含数组的键，您需要设置JSON_FORCE_OBJECT 选项（在PHP＆gt; = 5.3.0中可用）。

echo json_encode($arr, JSON_FORCE_OBJECT);

See demo

Answer 3

使用函数json_encode

示例：

echo json_encode($your_array);

Answer 4

<?php

  $your_array = array(
                      0 => array(
                                    0 => "your name",
                                    1 => "your email",
                                    2 => "your mobile"
                                ),
                      1 => array(
                                    0 => "Anjali",
                                    1 => "Anjali@gmail.com",
                                    2 => "999999999"
                                )            
                   );

foreach($your_array as $key=>$arr)
{
     $arr_temp = array();
     $i=0;
     foreach($arr as $k=>$v)
     {
        $i+=1;
        $arr_temp[$i] = $v;
     } 
     echo json_encode($arr_temp);
     echo "<br/>";
}

?>

OUPUPT：

{"1":"your name","2":"your email","3":"your mobile"}
{"1":"Anjali","2":"Anjali@gmail.com","3":"999999999"}
