## 定義和用法

xml_parse_into_struct() 函數把 XML 數據解析到數組中。

該函數把 XML 數據解析到 2 個數組中：

*   Value 數組 - 包含來自被解析的 XML 的數據
*   Index 數組 - 包含指向Value 數組中值的位置的指針

如果成功，則該函數返回 1。否則返回 0。

### 語法

```
xml_parse_into_struct(parser,xml,value_arr,index_arr)
```

| 參數 | 描述 |
| --- | --- |
| parser | 必需。規定要使用的 XML 解析器。 |
| xml | 必需。規定要解析的 XML 數據。 |
| value_arr | 必需。規定 XML 數據的目標數組。 |
| index_arr | 可選。規定 index 數據的目標數組。 |

## 提示和注釋

注釋：xml_parse_into_struct() 若失敗返回 0，成功則返回 1。這和 false 與 true 不同，使用例如 === 運算符時要注意。

## 例子

XML 文件：

```
<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<to>George</to>
<from>John</from>
<heading>Reminder</heading>
<body>Don't forget the meeting!</body>
</note>

```

PHP 代碼：

```
<?php
//無效 xml 文件
$xmlfile = 'test.xml';
$xmlparser = xml_parser_create();

// 打開文件并讀取數據
$fp = fopen($xmlfile, 'r');
$xmldata = fread($fp, 4096);

xml_parse_into_struct($xmlparser,$xmldata,$values);

xml_parser_free($xmlparser);
print_r($values);
?>
```

輸出：

```
