  2. $start = array_sum(explode(' ', microtime()));
  3. for($i=0;$i<10000;++$i) {
  4. strtotime("- 1 day");
  5. }
  7. $end = array_sum(explode(' ', microtime()));
  9. echo $end - $start ;
  10. echo '
    ';
  12. $start = array_sum(explode(' ', microtime()));
  14. for($i=0;$i<10000;++$i) {
  15. time() - 86400;
  16. }
  18. $end = array_sum(explode (' ', microtime()));
  20. echo $end - $start ;
  21. ?>
Copy the code

The output result is as follows: 1.13611793518 0.00332498550415

The efficiency difference is 400 times, which is indeed a big difference and deserves attention.
