如何从php数组中删除SimpleXMLElement对象

How to remove SimpleXMLElement Object from php array(如何从php数组中删除SimpleXMLElement对象)

问题描述

我已经使用simplexml_load_filephp函数读取了XML文件。

我已将XML数据存储到php数组中，但在某些数组中其显示数组为XML[2-1] 当我打印XML数据时，它显示正常，但当我将XML值赋给php数组时，它显示为数组中上述XML对象

XML

        <query>Anand, India</query>

            <precipMM>0.0</precipMM>
        </weather>
    </data>

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>";

推荐答案

我已使用以下代码解决了问题。

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>";
}
