JSOND: より優れた PHP JSON パーサー
まず、パフォーマンス テスト データを見てみましょう:
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 |
12
13 | 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 |
データ量が多い場合、jsond の方が json よりもはるかに高速であることがわかります。
インストールが成功したら、phpinfo:
使用法:
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 );
