在输出中获取额外的 <b> 标记

>我正在使用codeigniter v 3.x

现在我做了一个函数来加载带有模板的视图

    function load_guest($view,$data=array('data'=>''),$headerdata=array('data'=>''),$PageTitle='',$PageKeywords='',$PageDescription=''){
        $CI = & get_instance();  //get instance, access the CI superobject
        $headerdata['title']=$PageTitle;
        $headerdata['keyword']=$PageKeywords;
        $headerdata['description']=$PageDescription;
        $CI->load->view('partial/head',$headerdata);
        //Here i am getting opening <b> tag on html output
        $CI->load->view($view,$data);
        //Here i am getting closing </b> tag on html output
        $CI->load->view('partial/foot');
    }

但是当我在浏览器上加载任何页面后看到 html 源代码时。我在源中看到一对<b></b>标签。

我检查了我的整个项目并搜索了<b>标签，我确定我没有在任何地方使用<b>标签。

我使用 Phpstorm，所以我在路径中找到<b>标签，但什么也没找到......

编辑我也在使用钩子

function compress()
{
    ini_set("pcre.recursion_limit", "16777");
    $CI =& get_instance();
    $buffer = $CI->output->get_output();
    $re = '%# Collapse whitespace everywhere but in blacklisted elements.
        (?>             # Match all whitespans other than single space.
          [^'S ]'s*     # Either one ['t'r'n'f'v] and zero or more ws,
        | 's{2,}        # or two or more consecutive-any-whitespace.
        ) # Note: The remaining regex consumes no text at all...
        (?=             # Ensure we are not in a blacklist tag.
          [^<]*+        # Either zero or more non-"<" {normal*}
          (?:           # Begin {(special normal*)*} construct
            <           # or a < starting a non-blacklist tag.
            (?!/?(?:textarea|pre|script)'b)
            [^<]*+      # more non-"<" {normal*}
          )*+           # Finish "unrolling-the-loop"
          (?:           # Begin alternation group.
            <           # Either a blacklist start tag.
            (?>textarea|pre|script)'b
          | 'z          # or end of file.
          )             # End alternation group.
        )  # If we made it here, we are not in a blacklist tag.
        %Six';
    $new_buffer = preg_replace($re, " ", $buffer);
      // We are going to check if processing has working
    if ($new_buffer === null)
    {
        $new_buffer = $buffer;
    }
    $CI->output->set_output($new_buffer);
    $CI->output->_display();
}
