代码如下 function test(){
list($a,$b)= explode(" ",microtime());
return (float)$a+(float)$b;
}
echo $a;
$time = sprintf("%.12f",(double)test()-$a);
//方法二
代码如下 function ss_timing_start ($name = "default") {global $ss_timing_start_times;
$ss_timing_start_times[$name] = explode(" ", microtime());
}
function ss_timing_stop ($name = "default") {
global $ss_timing_stop_times;

}

}

$stop_time = explode(" ", microtime());
}

// do the big numbers first so the small ones aren"t lost
