time takes from sending some email

[WiZARD]

From manual to PHP:

Code: Select all

function getmicrotime(){
   list($usec, $sec) = explode(" ",microtime());
   return ((float)$usec + (float)$sec);
   }

$time_start = getmicrotime();
   
for ($i=0; $i < 1000; $i++){
   //do nothing, 1000 times
   }

$time_end = getmicrotime();
// mail procedure
mail(.......);
$time = $time_end - $time_start;

echo "succesfully sending email in $time seconds";
