json_decode 长整数,丢失精度,为何 window xp
在下面的php转换中:tid的精度会丢失,后面4位,6788,变成了7000 ,为何呢?

str='{"receiver_address":"四川遂宁市","receiver_city":"遂宁市","receiver_district":"射洪县","receiver_mobile":"15228662928","receiver_name":"蔡","receiver_state":"四川省","receiver_zip":"100218","sid":"114757372016788","tid":114757372016788}';

print_r(json_decode($str));exit;

测试环境:
A:centOS5+php5* 可以正确转换,
B: window xp +php526+Apache2.2 ,出错,丢失精度。

谢谢关注的亲们。

------解决方案--------------------
114757372016788 如果是数值的话,已超出 32 位机器的长整形所能表示的范围

你应该将其当做字符串处理,跟 sid 一样


------解决方案--------------------
编码问题吧
------解决方案--------------------
给数字两边加引号成字符串试一试
------解决方案--------------------
linux上安装的php模块和window上安装的不同, 或者php的配置不同, 所以json_decode的计算方法不一样。

如果你不懂怎么弄, 最简单的方法是当字符串处理, 在js脚本里转回整型数字。
