如何使用PHP将XML转换为数组？

我试图在数组中拆分XML，下面是我的php代码：

---

我不知道如何像上面的示例输出那样将它们设置到数组中。希望有人能帮助我。谢谢。

此代码片段将把XML转换为数组

$array = json_decode(json_encode((array)simplexml_load_string($xml)),true);
echo '<pre>';
print_r($array);

$array=json_decode（json_encode（（array）simplexml_load_string（$xml）），true）；
回声'；
打印（数组）；

然后您可以将其作为数组使用

步骤：

1） 首先使用

simplexml\u load\u string（）

将XML转换为可读的字符串对象

2） 然后

json\u encode（）

it

3）

json\u decode（）

it，带有第二个参数

TRUE

，它将返回数组而不是对象

4） 现在，XML被转换为数组

5） 取一个空白数组，从上面的代码循环数组并向其追加元素

要获得所需的输出：

Array
(
    [0] => Array
        (
            [title] => Java
            [tutor] => Gopal
            [duration] => 3
            [price] => $30
        )

    [1] => Array
        (
            [title] => Hadoop
            [tutor] => Satish
            [duration] => 3
            [price] => $50
        )

    [2] => Array
        (
            [title] => html
            [tutor] => raju
            [duration] => 5
            [price] => $50
        )

    [3] => Array
        (
            [title] => Web Technologies
            [tutor] => Javed
            [duration] => 10
            [price] => $60
        )

)

你的初始代码是创建一个数组的90%——不用担心json编码和解码，只需

$books[]=['title'=>$books->title'，tutor'=>$books->tutor…

代替你的

echo…

，别忘了先创建一个空白数组。

(
[0] => Array
    (
        [title] => Java
        [tutor] => Gopal
        [duration] => 3

    )

[1] => Array
    (
        [title] => Hadoop
        [tutor] => Satish
        [duration] => 3
        [price] => $50
    )

[2] => Array
    (
        [title] => HTML
        [tutor] => raju
        [duration] => 5
        [price] => $50
    )

[3] => Array
    (
        [title] => Web Technologies
        [tutor] => Javed
        [duration] => 10
        [price] => $60
    )

$array = json_decode(json_encode((array)simplexml_load_string($xml)),true);
echo '<pre>';
print_r($array);

<?php
$xml = '<?xml version = "1.0" encoding = "utf-8"?>

$arr = [];

   $arr[$i]['price'] = $elem['price'];
  ++$i;
