json_encode和json_decode的效率并没有比serialize和unserialize的效率高,在反序列化的时候性能相差两倍左右,PHP 5.3执行效率比PHP 5.2略有提升,代码如下:

1. <?php
2. $target = array (
3. 'name' => '全能头盔',
4. 'quality' => 'Blue',
5. 'ti_id' => 21302,
6. 'is_bind' => 1,
7. 'demand_conditions' =>
8. array (
9. 'HeroLevel' => 1,
10. ),
11. 'quality_attr_sign' =>
12. array (
13. 'HeroStrength' => 8,
14. 'HeroAgility' => 8,
15. 'HeroIntelligence' => 8,
16. ),
17. );
18. $json = json_encode($target);
19. $seri = serialize($target);
20. echo "json : " . strlen($json) . " ";
21. echo "serialize : " . strlen($seri) . " ";
22. $stime = microtime(true);
23. for ($i = 0; $i < 10000; $i ++)
24. {
25. json_encode($target);
26. }
27. $etime = microtime(true);
28. echo "json_encode : " . ($etime - $stime) . " ";
29. //----------------------------------
30. $stime = microtime(true);
31. for ($i = 0; $i < 10000; $i ++)
32. {
33. json_decode($json);
34. }
35. $etime = microtime(true);
36. echo "json_decode : " . ($etime - $stime) . " ";
37. //----------------------------------
38. $stime = microtime(true);
39. for ($i = 0; $i < 10000; $i ++)
40. {
41. serialize($target);
42. }
43. $etime = microtime(true);
44. echo "serialize : " . ($etime - $stime) . " ";
45. //----------------------------------
46. $stime = microtime(true);
47. for ($i = 0; $i < 10000; $i ++)
48. {
49. unserialize($seri); //开源代码phpfensi.com
50. }
51. $etime = microtime(true);
52. echo "unserialize : " . ($etime - $stime) . " ";
53. echo 'DONE.';
54. ?>
