如果你的网页内容的html标签显示不全,有些表格标签不完整而导致页面混乱,或者把你的内容之外的局部html页面给包含进去了,我们可以写个函数方法来补全html标签以及过滤掉无用的html标签.

php实现网页HTML标签补全方法

php使HTML标签自动补全闭合函数方法如下:

<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="code">
Copy after login
<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="code">
Copy after login

function closetags($html) {

preg_match_all('#<(?!meta|img|br|hr|input\b)\b([a-z]+)(?: .*)?(?#iU', $html, $result);

$openedtags = $result[1];

preg_match_all('##iU', $html, $result);

$closedtags = $result[1];

$len_opened = count($openedtags);

if (count($closedtags) == $len_opened) {

return $html;

}

$openedtags = array_reverse($openedtags);

for ($i=0; $i < $len_opened; $i++) {

if (!in_array($openedtags[$i], $closedtags)) {

$html .= '';

} else {

unset($closedtags[array_search($openedtags[$i], $closedtags)]);

}

}

return $html;

}

<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="code"><strong>解析: </strong>
Copy after login

array_reverse() : 此函数将原数组中的元素顺序翻转，创建新的数组并返回。如果第二个参数指定为 true，则元素的键名保持不变，否则键名将丢失。

array_search() : array_search(value,array,strict),此函数与in_array()一样在数组中查找一个键值。如果找到了该值，匹配元素的键名会被返回。如果没找到，则返回 false。 如果第三个参数strict被指定为 true，则只有在数据类型和值都一致时才返回相应元素的键名。
