局部分析

<?php
$token = Profiler::start('test', 'profiler');
for($i=0;$i<10000000;$i++){
	$sgr.='aa';
}
print_r(Profiler::total($token));
Profiler::stop($token);
Profiler::delete($token);

out:

Array

(

[0] => 2.28606700897

[1] => 20001440

)

0用时 1内存使用

但有多个$token时候,变为数组传给

$stats = Profiler::stats($tokens);

取得和group_stats()查不多的结果~
