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>
我要循环行并将它们添加到一个数组。 我通过它simplexml
通过这些对象,然后循环,但不能做到这一点:
$xml->rows
$xml->rows->row
$xml->row
$xml->column
我该怎么办?
谢谢。
这实际上是比较基本的例子之一:
$sxml = simplexml_load_string($xml);
foreach($sxml->rows->row as $name => $row)
{
echo $name, ': ', var_dump($row);
}
它会给你以下的输出:
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"
}
你可以在这里找到一个在线演示: http://codepad.org/CYyQhvnM
实际上,你应该看看手册中的简单exmamples部分,它具有的深度比我在这里解释的多一些很有见地的例子:
我希望答案是有帮助的反正。 相关的问题是:
- 如何使用的foreach使用PHP和XML(simplexml的)
S:您还可以,如果你更习惯阵列翻转简单的XML到一个数组
<?php
$xml = simplexml_load_file('./your.xml');
$json = json_encode($xml);
$array = json_decode($json,TRUE);
print_r($array);
/**
*Array
(
[rows] => Array
(
[row] => Array
(
[0] => Array
(
[column] => Array
(
[0] => 1
[1] => David
[2] => Johnson
)
)
[1] => Array
(
[column] => Array
(
[0] => 2
[1] => Jack
[2] => Nixon
)
)
)
)
)
*/
foreach($array['rows']['row'] as $row){
echo 'Id:'.$row['column'][0],
' Firstname:'.$row['column'][1],
' Lastname:'.$row['column'][2].'<br />'.PHP_EOL;
}
/*Result
Id:1 Firstname:David Lastname:Johnson<br />
Id:2 Firstname:Jack Lastname:Nixon<br />
*/
?>
或者成为一个更清洁例如通过hakra
<?php
$xml = simplexml_load_file('./test.xml');
$rows = json_decode(json_encode(iterator_to_array($xml->rows->row, 0)), 1);
print_r($rows);
/**
*
Array
(
[0] => Array
(
[column] => Array
(
[0] => 1
[1] => David
[2] => Johnson
)
)
[1] => Array
(
[column] => Array
(
[0] => 2
[1] => Jack
[2] => Nixon
)
)
)
*/
foreach($rows as $row){
echo 'Id:'.$row['column'][0],
' Firstname:'.$row['column'][1],
' Lastname:'.$row['column'][2].'<br />'.PHP_EOL;
}
如果你只是想通过行中循环:
<?php
$xmlstr = <<<XML
<?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>
XML;
$element = new SimpleXMLElement($xmlstr);
foreach($element->rows->row as $row) {
foreach($row as $column) {
echo "{$column}<br>";
}
echo "<hr>";
}
?>
$sxml = simplexml_load_string($xml);
$newArray = array();
foreach($sxml->rows as $num => $row){
foreach($row as $el){
(array)$newArray[] = (array)$el;
}
}
var_dump($newArray);
