如何从php数组中删除SimpleXMLElement对象

Question

我已经使用simplexml_load_file php函数读取了xml文件。

我有存储XML数据到PHP阵列，但在一些阵列它的XML的显示阵列like SimpleXMLElement Object ([0] => some value)

当我打印的XML数据，其显示正常但是当我XML值如上分配给PHP数组其显示在阵列XML对象

XML

PHP：

$child=$xml->children(); 
foreach($xml->children() as $child) 
{    
    foreach($child->children() as $child_t) 
    { 
     $weather_arr[$child_t->getName()]=$child_t; 
     echo $child_t->getName() . ": " . $child_t . "<br />"; 

    } 
} 

echo "<pre>".html_entity_decode(print_r($weather_arr,true))."</pre>"; 

Answer 1

我一直在使用下面的代码解决了我的问题。

function simplexml_to_array($xmlobj) { 
    $a = array(); 
    foreach ($xmlobj->children() as $node) { 
     if (is_array($node)) 
      $a[$node->getName()] = simplexml_to_array($node); 
     else 
      $a[$node->getName()] = (string) $node; 
    } 
    return $a; 
} 


foreach($xml->children() as $child) 
{ 
    $arr=simplexml_to_array($child); 
    echo "<pre>".html_entity_decode(print_r($arr,true))."</pre>"; 
}

这会给你一个简单的关联数组：

$array = json_decode(json_encode($xml), true);
