## 定義和用法

getName() 函數從 SimpleXMLElement 對象獲取 XML 元素的名稱。

如果成功，該函數返回當前的 XML 元素的名稱。如果失敗，則返回 false。

### 語法

```
class SimpleXMLElement
{
string getName()
}
```

## 例子

XML 文件：

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

PHP 代碼：

```
<?php
if (file_exists('test.xml'))
  {
  $xml = simplexml_load_file('test.xml');
  }

echo $xml->getName();

foreach($xml->children() as $child)
  {
  echo $child->getName();
  }
?>
```

輸出類似：

```
note
to
from
heading
body
```




                    
                
        
                
            
        
                
    
                
    
                
        
                
    
                

                







                  <ruby id="bdb3f"></ruby>
