如何在PHP中更改对象中JSON数组的输出？

php arrays json api

如何在PHP中更改对象中JSON数组的输出？,php,arrays,json,api,Php,Arrays,Json,Api,我有一个关于API JSON输出的问题。在循环中，我陷入JSON输出，当我强制数组格式更改为索引数组时，它生成自己的索引 PHP代码： $sql = "SELECT name,fname,address FROM user_management"; $array = array(); $result = $conn->query($sql); $i=1; if ($result->num_rows > 0) { // output data of each row

我有一个关于API JSON输出的问题。在循环中，我陷入JSON输出，当我强制数组格式更改为索引数组时，它生成自己的索引

PHP代码：

$sql = "SELECT name,fname,address FROM user_management";
$array = array();

$result = $conn->query($sql);
$i=1;

if ($result->num_rows > 0) {
    // output data of each row
    $array=["message"=>"success"];
    while($row = $result->fetch_assoc()) {

    $array[] = ["Hello" => $row];

 } 

} 
else 
{
    echo "0 results";
}
 //echo implode(',', $array);
 // Take output array glue it with the
echo json_encode($array);
$conn->close();
?>

我得到的答复如下：

{
  "message": "success",
  "0": {
    "Hello": {
      "name": "harjot",
      "fname": "tejinder",
      "address": "noida"
    }
  },
  "1": {
    "Hello": {
      "name": "regret",
      "fname": "egegrregeger",
      "address": "gegreg"
    }
  },
  "2": {
    "Hello": {
      "name": "harjot1",
      "fname": "harjot2",
      "address": "noida"
    }
  },
  "3": {
    "Hello": {
      "name": "har",
      "fname": "har1",
      "address": "Punjab"
    }
  }
}

我希望响应没有数组自己生成的0,1,2,3。是否有方法访问数组的索引

预期输出：

{   "message": "success",
    "Hello": {
      "name": "harjot",
      "fname": "tejinder",
      "address": "noida"   },
    "Hello1": {
      "name": "regret",
      "fname": "egegrregeger",
      "address": "gegreg"   },
    "Hello2": {
      "name": "harjot1",
      "fname": "harjot2",
      "address": "noida"   },
    "Hello3": {
      "name": "har",
      "fname": "har1",
      "address": "Punjab"
    }   
}

$array[] = ["Hello" => $row];

$array["Hello".$i] = $row;

<?php //
$sql = "SELECT name,fname,address FROM user_management";
$array = array();

$result = $conn->query($sql);
$i=1;

if ($result->num_rows > 0) {
    // output data of each row
    $array=["message"=>"success"];
    while($row = $result->fetch_assoc()) {

    $array["Hello".$i] = $row;//added line here
    $i++;//added this line to increment counter everytime.
 } 

} 
else 
{
    echo "0 results";
}
 //echo implode(',', $array);
 // Take output array glue it with the
echo json_encode($array);
$conn->close();
?>

您有维护计数器的

$i

声明，但您没有使用它

更改此选项：

{   "message": "success",
    "Hello": {
      "name": "harjot",
      "fname": "tejinder",
      "address": "noida"   },
    "Hello1": {
      "name": "regret",
      "fname": "egegrregeger",
      "address": "gegreg"   },
    "Hello2": {
      "name": "harjot1",
      "fname": "harjot2",
      "address": "noida"   },
    "Hello3": {
      "name": "har",
      "fname": "har1",
      "address": "Punjab"
    }   
}

$array[] = ["Hello" => $row];

$array["Hello".$i] = $row;

<?php //
$sql = "SELECT name,fname,address FROM user_management";
$array = array();

$result = $conn->query($sql);
$i=1;

if ($result->num_rows > 0) {
    // output data of each row
    $array=["message"=>"success"];
    while($row = $result->fetch_assoc()) {

    $array["Hello".$i] = $row;//added line here
    $i++;//added this line to increment counter everytime.
 } 

} 
else 
{
    echo "0 results";
}
 //echo implode(',', $array);
 // Take output array glue it with the
echo json_encode($array);
$conn->close();
?>

这个：

{   "message": "success",
    "Hello": {
      "name": "harjot",
      "fname": "tejinder",
      "address": "noida"   },
    "Hello1": {
      "name": "regret",
      "fname": "egegrregeger",
      "address": "gegreg"   },
    "Hello2": {
      "name": "harjot1",
      "fname": "harjot2",
      "address": "noida"   },
    "Hello3": {
      "name": "har",
      "fname": "har1",
      "address": "Punjab"
    }   
}

$array[] = ["Hello" => $row];

$array["Hello".$i] = $row;

<?php //
$sql = "SELECT name,fname,address FROM user_management";
$array = array();

$result = $conn->query($sql);
$i=1;

if ($result->num_rows > 0) {
    // output data of each row
    $array=["message"=>"success"];
    while($row = $result->fetch_assoc()) {

    $array["Hello".$i] = $row;//added line here
    $i++;//added this line to increment counter everytime.
 } 

} 
else 
{
    echo "0 results";
}
 //echo implode(',', $array);
 // Take output array glue it with the
echo json_encode($array);
$conn->close();
?>

同时添加

$i++用于维护和增加计数器值

试试这个
$i = 0;
while($row = $result->fetch_assoc()) {

    $array["Hello".$i++] = $row;

 } 

或
试试这个
$i = 0;
while($row = $result->fetch_assoc()) {

    $array["Hello".$i++] = $row;

 } 

或
试试这个
if ($result->num_rows > 0) {
    // output data of each row
    $array=["message"=>"success"];
    $index = "";
    while($row = $result->fetch_assoc()) {
        $array["Hello" . $index] = $row;
        $index = $index ? ($index + 1) : 1;
    }
} 

试试这个
if ($result->num_rows > 0) {
    // output data of each row
    $array=["message"=>"success"];
    $index = "";
    while($row = $result->fetch_assoc()) {
        $array["Hello" . $index] = $row;
        $index = $index ? ($index + 1) : 1;
    }
} 

从$array[]=[“Hello”=>$row]更改
到$array[“Hello”。$i]=$row输出已更改，但仍将获得具有0,1,2,3键的数组自己的索引。如何删除它们？在屏幕截图中显示您的代码。从$array[]=[“Hello”=>$row]更改
