PHP json_decode整数，并浮动到字符串 [英] PHP json_decode integers and floats to string

问题描述

我想预解析一个json，然后将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
}

对此:

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

更新 我发现了以下情况，但是它不适用于浮点数:

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 固定的第二个浮点值.它有两点.

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

推荐答案

使用此方法:应该可以使用

Use this: It should work

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