PHP json_encode将数字编码为字符串 [英] PHP json_encode encoding numbers as strings
问题描述
我遇到了PHP json_encode函数的一个问题。它将数字编码为字符串,例如
I am having one problem with the PHP json_encode function. It encodes numbers as strings, e.g.
array('id' => 3)
变为
"{ ["id": "3", ...)
当js遇到这些值时,它会将它们解释为字符串,并且数字操作会失败。有没有人知道某种方法来防止 json_encode
从编码数字作为字符串?谢谢!
When js encounters these values, it interprets them as strings and numeric operations fail on them. Does anyone know some way to prevent json_encode
from encoding numbers as strings? Thank you!
推荐答案
我做了一个非常快速的测试:
I've done a very quick test :
$a = array(
'id' => 152,
'another' => 'test',
'ananother' => 456,
);
$json = json_encode($a);
echo $json;
这似乎就像你描述的那样,如果我是没错?
This seems to be like what you describe, if I'm not mistaken ?
我得到的是输出:
{"id":152,"another":"test","ananother":456}
因此,在这种情况下,整数尚未转换为字符串。
So, in this case, the integers have not been converted to string.
尽管如此,这可能取决于我们使用的PHP版本:已经纠正了几个与json_encode相关的错误,具体取决于PHP的版本......
Still, this might be dependant of the version of PHP we are using : there have been a couple of json_encode related bugs corrected, depending on the version of PHP...
此测试是使用PHP 5.2.6进行的;我在PHP 5.2.9和5.3.0中得到了同样的东西;我没有其他5.2.x版本可供测试,但是: - (
This test has been made with PHP 5.2.6 ; I'm getting the same thing with PHP 5.2.9 and 5.3.0 ; I don't have another 5.2.x version to test with, though :-(
您使用的是哪个版本的PHP?或者您的测试用例比您发布的示例?
Which version of PHP are you using ? Or is your test-case more complex than the example you posted ?
可能有一个关于 http:/的错误报告/bugs.php.net/ 可能是相关的?例如, Bug#40503 :json_encode整数转换与PHP不一致?
Maybe one bug report on http://bugs.php.net/ could be related ? For instance, Bug #40503 : json_encode integer conversion is inconsistent with PHP ?
也许 Bug#38680 也会让你感兴趣,顺便说一下?
Maybe Bug #38680 could interest you too, btw ?
