非常优秀 PHP JSON解析器程序

首先，我们先来看看性能测试数据：

<table width="620" align="center" border="0" cellpadding="1" cellspacing="1" style="background:#FB7"> <tr> <td width="464" height="27" bgcolor="#FFE7CE"> 代码如下</td> <td width="109" align="center" bgcolor="#FFE7CE" style="cursor:pointer;" onclick="doCopy('copy5765')">复制代码</td> </tr> <tr> <td height="auto" colspan="2" valign="top" bgcolor="#FFFFFF" style="padding:10px;" class="copyclass" id=copy5765>

STR: {"i": 23, "array": [1, null, false, true, ["aha", "baba", 23, {"test": 23}]]}
JSON:  time for 100000 iterations: 0.238321
JSOND: time for 100000 iterations: 0.236436

STR: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
JSON:  time for 100000 iterations: 0.110764
JSOND: time for 100000 iterations: 0.134212

STR: {"a": 23.2234232}
JSON:  time for 100000 iterations: 0.078458
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.", }
JSON:  time for 100000 iterations: 0.881429
JSOND: time for 100000 iterations: 0.118529

STR: ... json_encode($_SERVER)
JSON:  time for 100000 iterations: 4.341252
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。

使用方法：

<table width="620" align="center" border="0" cellpadding="1" cellspacing="1" style="background:#FB7"> <tr> <td width="464" height="27" bgcolor="#FFE7CE"> 代码如下</td> <td width="109" align="center" bgcolor="#FFE7CE" style="cursor:pointer;" onclick="doCopy('copy7188')">复制代码</td> </tr> <tr> <td height="auto" colspan="2" valign="top" bgcolor="#FFFFFF" style="padding:10px;" class="copyclass" id=copy7188>

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 );
