PHP json_decode 整数和浮点数到字符串

问题描述

我想预先解析一个 json 并将 json 中的所有数字(整数或浮点数)转换为字符串.

I want to pre-parse a json an convert all numbers in the json (integers or float) to strings.

例如:

{
 "integer": 10000,
 "big_integer": 100000999499498485845848584584584,
 "float1" : 1.121212,
 "float2" : 8.226347662837406e+09
}

到这里:

{
 "integer": "10000",
 "big_integer": "100000999499498485845848584584584",
 "float1" : "1.121212",
 "float2" : "8226347662.837406"
}

更新我找到了以下，但是它不适用于浮动:

Update I have found the following but it does not work for floats:

$jsonString = '[{"name":"john","id":5932725006},{"name":"max","id":4953467146}]';

echo preg_replace('/("w+"):(d+)/', '\1:"\2"', $jsonString);
//prints [{"name":"john","id":"5932725006"},{"name":"max","id":"4953467146"}]

更新 2 修复了第二个浮点值.它有两点.

Update 2 Fixed second float value. It had two points.

推荐答案

使用这个:它应该可以工作

Use this: It should work

echo preg_replace('/: *([0-9]+.?[0-9e+-]*)/', ':"\1"', $jsonString);
