php - Getting extra <b> tag in output -

i using codeigniter v 3.x

now make function load viewes templates

    function load_guest($view,$data=array('data'=>''),$headerdata=array('data'=>''),$pagetitle='',$pagekeywords='',$pagedescription=''){         $ci = & get_instance();  //get instance, access ci superobject         $headerdata['title']=$pagetitle;         $headerdata['keyword']=$pagekeywords;         $headerdata['description']=$pagedescription;         $ci->load->view('partial/head',$headerdata);         //here getting opening <b> tag on html output         $ci->load->view($view,$data);         //here getting closing </b> tag on html output         $ci->load->view('partial/foot');     } 

but when see html source after loading page on browser. see pair of <b></b> tag source.

i checked whole project , search <b> tag , sure not using <b> tag anywhere.

i use phpstorm find in path <b> tag , nothing found...

edit using hook also

function compress() {      ini_set("pcre.recursion_limit", "16777");     $ci =& get_instance();     $buffer = $ci->output->get_output();     $re = '%# collapse whitespace everywhere in blacklisted elements.         (?>             # match whitespans other single space.           [^\s ]\s*     # either 1 [\t\r\n\f\v] , 0 or more ws,         | \s{2,}        # or 2 or more consecutive-any-whitespace.         ) # note: remaining regex consumes no text @ all...         (?=             # ensure not in blacklist tag.           [^<]*+        # either 0 or more non-"<" {normal*}           (?:           # begin {(special normal*)*} construct             <           # or < starting non-blacklist tag.             (?!/?(?:textarea|pre|script)\b)             [^<]*+      # more non-"<" {normal*}           )*+           # finish "unrolling-the-loop"           (?:           # begin alternation group.             <           # either blacklist start tag.             (?>textarea|pre|script)\b           | \z          # or end of file.           )             # end alternation group.         )  # if made here, not in blacklist tag.         %six';      $new_buffer = preg_replace($re, " ", $buffer);       // going check if processing has working     if ($new_buffer === null)     {         $new_buffer = $buffer;     }      $ci->output->set_output($new_buffer);     $ci->output->_display(); } 

i able solve problem using lazy trick.

in hook compress() function replace <br> tag manually.

$new_buffer = str_replace("<b>","",$new_buffer); $new_buffer = str_replace("</b>","",$new_buffer); $new_buffer = str_replace("</ b>","",$new_buffer); 

this partially solves problem. still want know, there better solution this?
