foreach和simplexml [英] foreach and simplexml
本文介绍了foreach和simplexml的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
这是我的xml文件:
<?xml version="1.0" encoding="utf-8" ?>
<documentElement>
<rows>
<row>
<column>1</column>
<column>David</column>
<column>Johnson</column>
</row>
<row>
<column>2</column>
<column>Jack</column>
<column>Nixon</column>
</row>
</rows>
</documentElement>
我想遍历行并将它们添加到数组中.我将其传递给simplexml
,然后遍历这些对象,但无法做到这一点:
I want to loop over rows and add them to an array. I passed it to simplexml
and then loop through these objects, but couldn't do it:
$xml->rows
$xml->rows->row
$xml->row
$xml->column
我该怎么办?
谢谢.
推荐答案
这实际上是更基本的示例之一:
This is actually one of the more basic examples:
$sxml = simplexml_load_string($xml);
foreach($sxml->rows->row as $name => $row)
{
echo $name, ': ', var_dump($row);
}
将为您提供以下输出:
row: object(SimpleXMLElement)#3 (1) {
["column"]=>
array(3) {
[0]=>
string(1) "1"
[1]=>
string(5) "David"
[2]=>
string(7) "Johnson"
}
}
row: object(SimpleXMLElement)#5 (1) {
["column"]=>
array(3) {
[0]=>
string(1) "2"
[1]=>
string(4) "Jack"
[2]=>
string(5) "Nixon"
}

您实际上应该看一下手册中的简单示例部分,其中有一些非常有见地的示例,在这里比我更深入地解释了这些示例:
You should actually take a look at the simple exmamples section in the manual, it has some very insightful examples that are explained more in depth than mine here:
