PHP将XML输出作为数组读取 - PHP read XML output as array

PHP read XML output as array

本文关键字：数组读取输出 XML PHP | 更新日期: 2023-09-27

我正在遍历XML文件中的节点值，但无法获得所需的输出。下面是我正在使用的代码。

PHP:

$xml = simplexml_load_file("file.xml") or die("Error: Cannot create object");         
$result = array();
foreach($xml->picture as $item)
{
     $result[]  =  $item->logo;
}
echo '<pre>';
print_r($result);
echo '</pre>';

当前输出:

Array
(
    [0] => SimpleXMLElement Object
        (
            [0] => img/a.jpg
        )
    [1] => SimpleXMLElement Object
        (
            [0] => img/b.jpg
        )
    [2] => SimpleXMLElement Object
        (
            [0] => img/c.jpg
        )
    ...
 )

所需输出:

Array
(
    [0] => a.jpg
    [1] => b.jpg
    [2] => c.jpg
    ...
)

function toArray(SimpleXMLElement $xml) {
    $array = (array)$xml;
    foreach ( array_slice($array, 0) as $key => $value ) {
        if ( $value instanceof SimpleXMLElement ) {
            $array[$key] = empty($value) ? NULL : toArray($value);
        }
    }
    return $array;
}

在数组中分配循环的编号，您的代码保持如下:

$xml = simplexml_load_file("file.xml") or die("Error: Cannot create object");         
$result = array();
$i = 0;//set a variable to loop throw the foreach
foreach($xml->picture as $item)
    {
//assign the variable with the number of the loop in the disired array
         $result[$i]  =  $item->logo;
    }
echo '<pre>';
print_r($result);
echo '</pre>';
