JSOND--一个更优的PHP JSON解析器

JSOND：一个更优的PHP JSON解析器

首先，我们先来看看性能测试数据：

01	STR: { "i" : 23, "array" : [1, null, false, true, [ "aha" , "baba" , 23, { "test" : 23}]]}

02	JSON: time for 100000 iterations: 0.238321

03	JSOND: time for 100000 iterations: 0.236436

04

05	STR: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

06	JSON: time for 100000 iterations: 0.110764

07	JSOND: time for 100000 iterations: 0.134212

08

09	STR: { "a" : 23.2234232}

10	JSON: time for 100000 iterations: 0.078458

11	JSOND: time for 100000 iterations: 0.055479

STR: { "long-str" : "At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident, similique sunt in culpa qui officia deserunt mollitia animi, id est laborum et dolorum fuga. Et harum quidem rerum facilis est et expedita distinctio. Nam libero tempore, cum soluta nobis est eligendi optio cumque nihil impedit quo minus id quod maxime placeat facere possimus, omnis voluptas assumenda est, omnis dolor repellendus. Temporibus autem quibusdam et aut officiis debitis aut rerum necessitatibus saepe eveniet ut et voluptates repudiandae sint et molestiae non recusandae. Itaque earum rerum hic tenetur a sapiente delectus, ut aut reiciendis voluptatibus maiores alias consequatur aut perferendis doloribus asperiores repellat." , }

14	JSON: time for 100000 iterations: 0.881429

15	JSOND: time for 100000 iterations: 0.118529

16

17	STR: ... json_encode($_SERVER)

18	JSON: time for 100000 iterations: 4.341252

19	JSOND: time for 100000 iterations: 1.960814

可以看到在大数据量的时候jsond的速度比json快多了。

根据自身情况，选择相应的安装方法，安装成功后，查看phpinfo:

使用方法：

mixed jsond_decode ( string $json [, bool $assoc = false [, int $depth = 512 [, int $options = 0 ]]] );string jsond_encode ( mixed $value [, int $options = 0 [, int $depth = 512 ]] );string jsond_last_error_msg ( void );int jsond_last_error ( void );
