问题描述
这是标记。
< div class =coursesListed>
< ul>
< li>< a href =#>< h3>项目1< / h3>< / a>< / li>
< li>< a href =#>< h3>项目2< / h3>< / a>< / li>
< li>< a href =#>< h3>项目3< / h3>< / a>< / li>
< / ul>
< / div>
我想要的是一个变量或数组,它包含值Item one,Item两个,项目三。
解决方案
尝试这个
$ html ='< div class =coursesListed>
< ul>
< li>< a href =#>< h3>项目1< / h3>< / a>< / li>
< li>< a href =#>< h3>项目2< / h3>< / a>< / li>
< li>< a href =#>< h3>项目3< / h3>< / a>< / li>
< / ul>
< / div>';
$ doc = new DOMDocument();
$ doc-> loadHTML($ html);
$ liList = $ doc-> getElementsByTagName('li');
$ liValues = array();
foreach($ liList as $ li){
$ liValues [] = $ li-> nodeValue;
}
var_dump($ liValues);
Im trying to store the string value's of a list item on my website into a variable/array in PHP to do some conditional checks/statements with them. Am having a bit off difficulty getting the list item's string value using PHP, can anybody help?
This is the markup.
<div class="coursesListed">
<ul>
<li><a href="#"><h3>Item one</h3></a></li>
<li><a href="#"><h3>item two</h3></a></li>
<li><a href="#"><h3>Item three</h3></a></li>
</ul>
</div>
What i want ideally is either a variable or array that holds the values "Item one", "Item two", "Item three".
解决方案
Try this
$html = '<div class="coursesListed">
<ul>
<li><a href="#"><h3>Item one</h3></a></li>
<li><a href="#"><h3>item two</h3></a></li>
<li><a href="#"><h3>Item three</h3></a></li>
</ul>
</div>';
$doc = new DOMDocument();
$doc->loadHTML($html);
$liList = $doc->getElementsByTagName('li');
$liValues = array();
foreach ($liList as $li) {
$liValues[] = $li->nodeValue;
}
var_dump($liValues);
