During the article saving process, you need to obtain the text in the html content edited by the Uediter editor on the front end. The basic idea is to use PHP's own function strip_tags() to directly filter

So edit it directly as follows:

$data   = $this->request->param();
$data['post']['content'] = strip_tags($data['post']['post_content']);
 
echo  $data['post']['post_content'];
echo  $data['post']['content'];

The output content is as follows, the strip_tags() function does not play a role:

<p>RWERWERWhgj<strong>ghhfhgn</strong>bfghgh</p>
<p>RWERWERWhgj<strong>ghhfhgn</strong>bfghgh</p>

Looking at the TP5 manual-input variable chapter-variable filtering we can find out By default, TP5 uses htmlspecialchars to convert the string passed from the front end into HTML entities. Therefore, my solution is to reverse the converted entities. This can be achieved by using the htmlspecialchars_decode() function:

$data   = $this->request->param();
$data['post']['content'] = strip_tags(htmlspecialchars_decode($data['post']['post_content']));
 
echo  $data['post']['post_content'];
echo  $data['post']['content'];

The output is as follows, the conversion is successful:

<p>RWERWERWhgj<strong>ghhfhgn</strong>bfghgh</p>
RWERWERWhgjghhfhgnbfghgh
