  <?php 

  echo $m1 = memory_get_usage(); 

  echo "<br />";

   

  echo $m2 = memory_get_usage()-$m1; 

  echo "<br />";

   

  echo $m3 = memory_get_usage()-$m1-$m2; 

  echo "<br />";

   

  echo $m4 = memory_get_usage()-$m1-$m2-$m3; 

  echo "<br />";

   

  echo $m5 = memory_get_usage()-$m1-$m2-$m3-$m4; 

  ?>

  大神请问一下

  echo $m2 = memory_get_usage()-$m1; 

  echo "<br />";

  这个是什么意思右边为什么显示144呢
