json - PHP json_decode integers and floats to string

Question

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

For example:

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

to this:

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

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"}]

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

Use JSON_BIGINT_AS_STRING option:

json_decode($jsonString, false, 512, JSON_BIGINT_AS_STRING)
