页面生成时间为人性化的格式

Question

function PageStartTime() { 
     $time = microtime(); 
     $time = explode(' ', $time); 
     $time = $time[1] + $time[0]; 
     $start = $time; 
    } 

function pageFinishTime() { 
     $time = microtime(); 
     $time = explode(' ', $time); 
     $time = $time[1] + $time[0]; 
     $finish = $time; 
     $total_time = round(($finish - $start), 1); 
     echo "Page generated in $total_time seconds."; 
     echo 'Peak memory usage: ',round(memory_get_peak_usage()/1048576, 2), 'MB'; 
    } 

打印：

页中1473241297.4 seconds.Peak内存使用情况产生：0.56MB

我怎样才能改变"human-friendly"格式？

我不知道您使用的类或没有，但如果没有，你必须有一定的参考$开始时间;

private $start = 0; 

function PageStartTime() { 
    $this->start = microtime(true); 
} 

function pageFinishTime() { 
     $finish = microtime(true); 
     $total_time = round(($finish - $this->start), 4); 
     echo "Page generated in $total_time seconds."; 
     echo 'Peak memory usage: ',round(memory_get_peak_usage()/1048576, 2), 'MB'; 
    }
