I have array like:
$array = ['id' => '76561198165327575'];
And I need it to work in JavaScript on client side. So I'm trying to encode it with JSON_NUMERIC_CHECK:
json_encode($array, JSON_NUMERIC_CHECK);
And getting result like:
{"id":7.6561198165328e+16}
But it should be:
{"id":76561198165327575}
What is wrong?

JSON_NUMERIC_CHECK basically tells the encoder "If it looks like a number, encode it as a number":
php > $x = '123456789012234567890';
php > echo json_encode($x, JSON_NUMERIC_CHECK);
1.2345678901223e+20
php > echo json_encode($x);
"123456789012234567890"
And since your number exceeds the representable range for an INT on your platform, you get a float instead.
JSON_BIGINT_AS_STRING.You are exceeding the bounds of integer on your 32-bit system. The documentation describes that when this occurs, the number is converted to a float.
If PHP encounters a number beyond the bounds of the integer type, it will be interpreted as a float instead. Also, an operation which results in a number beyond the bounds of the integer type will return a float instead.
If you encode in JSON objects with large numbers (greater than PHP_MAX_INT), you will always end up getting a floating point value. The only solution is to store them in the object/array as string (that you already) and not use JSON_NUMERIC_CHECK (but convert the string to a number on the client) or write your own encoding routine.
