php修復16498行TCPDF的迷你錯誤：未定義索引：線程

Question

創建pdf時可能會出現錯誤，我需要面對它。

PHP版本5.3

TCPDF版本6.2

if (($dom[$key]['value'] == 'table') AND (!TCPDF_STATIC::empty_string($dom[($dom[$key]['parent'])]['thead']))) 
    { 
     $dom[($dom[$key]['parent'])]['thead'] = str_replace(' nobr="true"', '', $dom[($dom[$key]['parent'])]['thead']); 
     $dom[($dom[$key]['parent'])]['thead'] .= '</tablehead>'; 
    }

這裏是一個只需要檢查數組元素中的溶液。

if (array_key_exists ('thead',$dom[($dom[$key]['parent'])])) 
{ 
        if (($dom[$key]['value'] == 'table') AND (!TCPDF_STATIC::empty_string($dom[($dom[$key]['parent'])]['thead']))) { 
        $dom[($dom[$key]['parent'])]['thead'] = str_replace(' nobr="true"', '', $dom[($dom[$key]['parent'])]['thead']); 
        $dom[($dom[$key]['parent'])]['thead'] .= '</tablehead>'; 
        } 
}
