optimize_memory

optimize_memory(); - optimize the memory used by the program (sometimes it gives a temporary effect and then you should use the commands or restart the application or recreate the browser ).

After testing, the function returns the result of its work to the script :
  • true – the operation was completed successfully
  • true – errors occurred during the operation

    PHP example: 

    <?php $xhe_host = "127.0.0.1:7017";
 
//connect the object to control the emulator, if not already connected
if(!isset($path))
  $path = "../../../Templates/xweb_human_emulator.php";
require($path);
 
//resources
echo "<hr> <font color = blue> debug->".basename(__FILE__)."</font> <hr>";
 
//memory
$begmem = $debug->get_cur_mem_size();
$gdi = $debug->get_gui_resources(0);
$user = $debug->get_gui_resources(1);
 
//check the efficiency of cleaning memory
$num = 0;
for($i = 0; $i <5; $i ++)
{
  //create a tab
   $browser->set_count(2);
