我在textfile中有一个字符串
我试图从这个文件中获取文本并推送到xml属性值
这是我的代码: -
<?php
$region = file_get_contents('activity.text');
$arr1 = explode(',',$region);
$arr1[array_rand($arr1)];
$ran1 = $arr1;
// create doctype
$dom = new DOMDocument("1.0");
// display document in browser as plain text
// for readability purposes
header("Content-Type: text/plain");
// create root element
$root = $dom->createElement("products");
$dom->appendChild($root);
//for($i=0,$j=351;$i<count($arr1);$i++,$j++)
for($i=0;$i<2;$i++)
{
$pro_id = $dom->createElement("product_id");
$root -> appendChild($pro_id);
//append attribute ib product_id
$attpro = $dom->createAttribute("value");
$pro_id -> appendChild($attpro);
//append attribue value in product_id
$attval = $dom->createTextNode($i+1);
$attpro -> appendChild($attval);
// create child dist_region
$dist_region = $dom->createElement("dist_region");
$pro_id->appendChild($dist_region);
// create attribute node
$attreg = $dom->createAttribute("value");
$dist_region->appendChild($attreg);
// create attribute value node
$attval = $dom->createTextNode("$ran1[$i]");
$attreg->appendChild($attval);
}
echo $dom->saveXML();
?>
这是我的字符串(region.txt): -
10066,10067,10068,10069,10070,10071,10072,5
这里我尝试将文本从字符串中随机推送到xml文件作为属性值,我的代码输出为: -
<products>
<product_id value="1">
<dist_activity value="10066"/>
<dist_activity value="10066"/>
</product_id>
<product_id value="2">
<dist_activity value="10067"/>
<dist_activity value="10067"/>
</product_id>
</products>
我想输出类似这样的输出: -
<?xml version="1.0"?>
<products>
<product_id value="1">
<dist_activity value="10066"/>
<dist_activity value="10069(any thing not same)"/>
</product_id>
<product_id value="2">
<dist_activity value="10067"/>
<dist_activity value="10072(any thing not same)"/>
</product_id>
</products>
从字符串
中随机获取属性值
谢谢...
答案 0 :(得分:0)
我认为问题更多的是将值放入所希望的顺序而不是添加XML元素。一些提示:
shuffle()
随机化整个数组。请参阅http://php.net/shuffle array_chunk()
分别创建一组两个值。请参阅http://php.net/array_chunk 代码示例:
$values = explode(',', '10066,10067,10068,10069,10070,10071,10072,5');
shuffle($values);
$groups = array_chunk($values, 2);
print_r($groups);
$count = count($groups);
foreach ($groups as $index => $group)
{
$last = $index+1 === $count;
printf(" %s─ product_id: %d\n", $last ? '└' : '├', $index + 1);
foreach ($group as $subindex => $value)
{
printf(" %s %s─ dist_activity: %s\n", $last ? ' ' : '│', $subindex ? '└' : '├', $value);
}
if (!$last) print(" │\n");
}
输出:
Array
(
[0] => Array
(
[0] => 10069
[1] => 10068
)
[1] => Array
(
[0] => 10072
[1] => 10067
)
[2] => Array
(
[0] => 5
[1] => 10070
)
[3] => Array
(
[0] => 10071
[1] => 10066
)
)
