好吧，我承认我只是为了了解一下这3个函数的效率如何
-
function microtime_float() {
-
list($usec, $sec) = explode(" ", microtime());
-
return ((float)$usec + (float)$sec);
-
}
-
$time_start = microtime_float(); // Sleep for a while include(‘test’.$argv[1].’.php’);
-
$time_end = microtime_float();
-
$time = $time_end – $time_start;
-
echo " time use:$time";
-
$test=array(‘asdfasf’,'asdfasdfasdf’,'asdf’=>’aasqtwetqwet’,161346=>14361235);
-
-
for($i=0;$i<10000;$i++)
-
if(json_encode($test)!=json_encode($test))
-
break;
-
echo $i;
-
$test=array(‘asdfasf’,'asdfasdfasdf’,'asdf’=>’aasqtwetqwet’,161346=>14361235);
-
-
for($i=0;$i<10000;$i++)
-
if(serialize($test)!=serialize($test))
-
break;
-
echo $i;
命名为test1.php test2.php test3.php….
执行php test.php 1(这就跑test1.php)了
执行结果是
print_r最慢 0.2左右
serialize和json差不多json稍慢一点。。大概是0.07 0.06的样子
