Cannot decode JSON long value (results to 2147483647)

[rjjuu...@gmail.com]

Hello,

I'm trying to decode a JSON encoded string. This string contains a big
value (of type long).
The result in PHP is always 2147483647 (PHP s max integer value), see
the code below.

How to make PHP aware of the fact that we deal with a long value?

<?php

$input = '{ "abc" : 121212121212 }';
$val = json_decode($input, true);

echo '<pre>';
echo var_dump($val);
echo '</pre>';

?>

array(1) {
["abc"]=>
int(2147483647)
}

just ran across this problem today...
here's a quick fix, modify the json_create_zval function in
JSON_parser.c to the code below so it just treats everything as a
string...
I'm sure there is a better way to fix this problem, but i just spent a
minute to quickly fix the problems i was having.

static void json_create_zval(zval **z, smart_str *buf, int type)
{
ALLOC_INIT_ZVAL(*z);

if (type == IS_LONG)
{
ZVAL_STRINGL(*z, buf->c, buf->len, 1);
}
else if (type == IS_DOUBLE)
{
ZVAL_STRINGL(*z, buf->c, buf->len, 1);
}
else if (type == IS_STRING)
{
ZVAL_STRINGL(*z, buf->c, buf->len, 1);
}
else if (type == IS_BOOL)
{
ZVAL_STRINGL(*z, buf->c, buf->len, 1);
}
else /* type == IS_NULL) || type unknown */
{
ZVAL_NULL(*z);
}
}

Try this patch:

http://treehou.se/~omar/php-json-ext-1.2.1-32bit_int.patch

This bug exists as I don't have any 32bit machines in active use. ;)

I'll be sure to test this on future releases.

Thanks.
