在不剪切标签的情况下拆分HTML

I've been trying to split a PHP string in an arbitrary number of characters per split. However, I'm looking for a way to do so without breaking HTML tags. Here is an example:

我一直试图在每次拆分时以任意数量的字符拆分PHP字符串。但是,我正在寻找一种不破坏HTML标签的方法。这是一个例子:

$string = 'Section 1: 
<table width = "528" border="0" cellpadding="0" cellspacing="0">
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 1 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 2 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 3 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top">&bull; </td>    <td valign="top"> Element 4 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 5 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 6 </td></tr>
</table>

Section 2:
<table width = "528" border="0" cellpadding="0" cellspacing="0">
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 7 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 8 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 9 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 10 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 11 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 12 </td></tr>
<tr>    <td width="20"> </td>   <td width="15" valign="top"> &bull; </td>   <td valign="top"> Element 13 </td></tr>
</table>';

$charAmount = 450;
$textSplit = array();

while ($string){
    array_push($textSplit, substr($string, 0, $charAmount));
    $string = substr($string, $charAmount);
}

var_dump($textSplit);

In this case, two tags are broken. I'd like whatever tag that is cut up at the end of a split to just skip to the next split, but I have no idea how to do this.

在这种情况下,两个标签被打破。我喜欢在分割结束时切换的任何标签只是跳到下一个分割,但我不知道如何做到这一点。

I'm not php guys, But logicwise I can help, just before split check which of dese two character is present nearest backwards from the split index < or >

我不是php的人,但逻辑上我可以提供帮助,就在拆分之前检查哪个dese两个字符最接近拆分索引 <或>

if < is encountered u r splitting in wrong place so skip

如果 <遇到你在错误的地方分裂,那么跳过< p>

if > is encountered go ahead with split

如果>遇到>继续拆分

I have done it in jQuery successfully sometimes back

我有时成功地在jQuery中完成了它
