考虑如下所示的html代码
<html>
<div class="allItems">
<div class="Item" id="12345">
<div class="ItemName">Tom</div>
<div class="ItemAge">34</div>
<div class="ItemGender">male</div>
</div>
<div class="Item" id="17892">
<div class="ItemName">Dick</div>
<div class="ItemAge">23</div>
<div class="ItemGender">male</div>
</div>
<div class="Item" id="98776">
<div class="ItemName">Harry</div>
<div class="ItemAge">65</div>
<div class="ItemGender">male</div>
</div>
</div>
</html>
我正在尝试如下解析这个html文档：
<?php
include_once("/simple_html_dom.php");
<--a bunch of code that works until here -->
$html = str_get_html($str); //this pulls the html code fine
//this is where my array constructions does not work
foreach ($html->find('div.allItems > *') as $article) {
$item['name'] = $html->find('div.ItemName', 0)->plaintext;
$item['age'] = $html->find('div.ItemAge',0)->plaintext;
$item['gender'] = $html->('div.ItemGender', 0)->plaintext;
$articles[] = $item;
}
print_r($articles);
?>
我期望得到的：
Array ( [0] => Array ( [name] => Tom [Age] => 34 [Gender] => male )
[1] => Array ( [name] => Dick [Age] => 23 [Gender] => male )
[2] => Array ( [name] => Harry [Age] => 65 [Gender] => male )
相反，这就是我得到的
Array ( [0] => Array ( [name] => Tom [Age] => 34 [Gender] => male )
[1] => Array ( [name] => Tom [Age] => 34 [Gender] => male )
[2] => Array ( [name] => Tom [Age] => 34 [Gender] => male )
因此，我的问题是：
如何获得所需的数组？
您的做法是正确的，唯一的想法是需要将div的索引设置为find函数的第二个参数。看看下面的解决方案：
include_once("simple_html_dom.php");
$str = '<html>
<div class="allItems">
<div class="Item" id="12345">
<div class="ItemName">Tom</div>
<div class="ItemAge">34</div>
<div class="ItemGender">male</div>
</div>
<div class="Item" id="17892">
<div class="ItemName">Dick</div>
<div class="ItemAge">23</div>
<div class="ItemGender">male</div>
</div>
<div class="Item" id="98776">
<div class="ItemName">Harry</div>
<div class="ItemAge">65</div>
<div class="ItemGender">male</div>
</div>
</div>
</html>';
$html = str_get_html($str); //this pulls the html code fine
//this is where my array constructions does not work
$i = 0;
foreach ($html->find('div.allItems > *') as $article) {
$item['name'] = $html->find('div.ItemName', $i)->plaintext;
$item['age'] = $html->find('div.ItemAge',$i)->plaintext;
$item['gender'] = $html->find('div.ItemGender', $i)->plaintext;
$articles[] = $item;
$i++;
}
print_r($articles);
输出：
Array
(
[0] => Array
(
[name] => Tom
[age] => 34
[gender] => male
)
[1] => Array
(
[name] => Dick
[age] => 23
[gender] => male
)
[2] => Array
(
[name] => Harry
[age] => 65
[gender] => male
)
)
