[Vtigercrm-developers] performance and profiling

[Alan Bell]

turns out that most of what to_html is processing is very repetitive, if 
it just populates an array as it goes along and then checks in that 
array it is a lot faster than doing htmlentities on the string every time.

global $htmlcache;//store the stripped HTML as we go along, a lot of the 
time we are processing the same strings
function to_html($string, $encode=true)
{
         global $doconvert;
         global $default_charset;
         global $htmlcache;
         if($doconvert){
                 if(isset($htmlcache[$string])){
                     return $htmlcache[$string];
                 }else{
                     $clean= htmlentities($string, ENT_QUOTES, 
$default_charset);//we don't care if it is a string or not, faster not 
to care
                     $htmlcache[$string]=$clean;
                     return $clean;
                 }
         }else{
                 return $string;
         }
