 public function gettext($text){       if(!empty($text)){           $dom = new domdocument();           $dom->loadhtml($text);            $xpath=new domxpath($dom);           $result = $xpath->query('//a');            if($result->length > 0){               $atags=$dom->getelementsbytagname('a');               foreach($atags $atag){                   $style = $atag ->getattribute('style');                   $atag->setattribute('style',$style.' text-decoration:none;color:black;');               }               $returntext .= $dom->savehtml();               return $returntext;           }            $result = $xpath->query('//table');           if($result->length > 0){               $tables = $dom->getelementsbytagname('table');                             $inputs = $dom->getelementsbytagname('input');                foreach ($inputs $input) {                   $input->setattribute('style','text-align:center;');               }                foreach ($tables $table) {                   $table->setattribute('width',500);                   $table->setattribute('style','border:2px solid #8c8c8c;text-align:center;table-layout:fixed;');               }               $returntext .= $dom->savehtml();               return $returntext;           }       }       return $text;   }    public function gettextwithindex($text,$index=''){       if(!empty($text[$index])){           $dom = new domdocument();           $dom->loadhtml($text[$index]);            $xpath=new domxpath($dom);           $result = $xpath->query('//a');            if($result->length > 0){               $atags=$dom->getelementsbytagname('a');               foreach($atags $atag){                   $style = $atag ->getattribute('style');                   $atag->setattribute('style',$style.' text-decoration:none;color:black;');               }               $returntext .= $dom->savehtml();               return $returntext;           }            $result = $xpath->query('//tbody');           if($result->length > 0){               $tbodies = $dom->getelementsbytagname('tbody');               $cells = $dom->getelementsbytagname('td');               $inputs = $dom->getelementsbytagname('input');                foreach ($inputs $input) {                   $input->setattribute('style','text-align:center;');               }                foreach ($cells $cell) {                   $cell->setattribute('style','border:1px solid black;');               }                foreach ($tbodies $tbody) {                   $table = $dom->createelement('table');                   $table->setattribute('width',500);                   $table->setattribute('style','border:2px solid #8c8c8c;text-align:center;table-layout:fixed;');                    $tbody->parentnode->replacechild($table, $tbody);                   $table->appendchild($tbody);               }               $returntext .= $dom->savehtml();               return $returntext;           }       }       return $text;   } 

the difference between method $index , modification of domdocument. feel it's cumbersome , use refactoring. have suggestions? thanks!

how this:

public function gettextwithindex($text,$index='') {     if (empty($index))         return gettext($text); //not sure how $text works, line might different.      return gettext($text[$index]); } 

or this:

public function gettext($text, $index = false){     if ($index)         $text = $text[$index];   if(!empty($text)){       $dom = new domdocument();       $dom->loadhtml($text);        $xpath=new domxpath($dom);       $result = $xpath->query('//a');        if($result->length > 0){           $atags=$dom->getelementsbytagname('a');           foreach($atags $atag){               $style = $atag ->getattribute('style');               $atag->setattribute('style',$style.' text-decoration:none;color:black;');           }           $returntext .= $dom->savehtml();           return $returntext;       }        $result = $xpath->query('//table');       if($result->length > 0){           if ($index) {               //do 'gettextwithindex' dom stuff           } else {               $tables = $dom->getelementsbytagname('table');                             $inputs = $dom->getelementsbytagname('input');           }            foreach ($inputs $input) {               $input->setattribute('style','text-align:center;');           }            foreach ($tables $table) {               $table->setattribute('width',500);               $table->setattribute('style','border:2px solid #8c8c8c;text-align:center;table-layout:fixed;');           }           $returntext .= $dom->savehtml();           return $returntext;       }   }   return $text;
