I like Abraham's idea: Twitter could add: next_cursor_string:1314614526448841129 Or a general return_as_string parameter which would return all values as strings. This would solve the problem for future values that might exceed the max int. There are going to be a lot of devs using PHP that don't have the option to switch to 64 bit or make any php.ini changes.

I'm sorry, but the problem isn't Twitter- its your language and JSON parser. Outputting everything as a string, when it clearly should be a number, is inefficient and crazy. Saying that startups can't afford 64 bit processors in systems is crazy. Most startups I know are running on EC2 or have fairly new hardware. I bought a killer 64-bit quad xeon server for less than $1,500 for our startup and its rocking. If your startup doesn't have $1,500 for a primary capital computing expense that's another problem you have there. You either need to run on a newer system or use a language that can properly handle 64-bit numbers. C, Python, Ruby, Scala, Erlang, C#, etc none of them have problems with 64-bit ints. Not a Twitter problem. It's a programming issue on your end and unfortunately I can't help as I don't know PHP in depth. -dave On Sep 24, 3:29 pm, Dewald Pretorius dpr...@gmail.com wrote: That magical maximum number appears to be 1 (1.0E+12).

I don't think anyone's saying it's Twitter's problem (at least I hope not). It's the same issue as supporting Internet Explorer. You can bitch and complain all you want about IE not supporting standards but if it's the most popular (or one of the most popular) browsers that are in use --- then practical beats principle. My suggestion was to return everything as a string if that's how it's being requested. It's a safe backwards compatible addition that doesn't affect anyone that doesn't run into this problem. If your scope is limited to what startups can or can't afford, then that's really narrow. This applies to anyone consuming the API be than on a laptop for development or anything else.

I tend to agree, a MacMini, around 600.00, would build php out as 64 bit no issue. If you are a baby startup, that should really cover you and be able to handle a lot more load than you would think. You may have to pop your database on something more robust, but it works quite well as a php front end. Take it to 1000.00 or so, and you can built out your own 1U server that is going to hold it's own very very well. Or, rent a 1U, they are a few hundred bucks a month, you get to pick the OS, pick the bit'ness, etc. If you are a startup, on a shoestring, part of the fun is being creative, and making due with what you have. And don't laugh at that MacMini, you can easily get to the SATA port, and plug it right into a SATA array elsewhere, getting SATA II on full size dives. I just pegged the drives to a cork board, its not pretty, but it works. I have a second on standby in case that one craps. I just had them laying around, and made them up from parts. While I am not going to mention the site, I can tell you, it is php on the front, apache2 with a good deal of mod_rewriting going on, and substantial database work, all happening on the MacMini, handling 500,000+ average unique visitors, which is a lot more requests when you add in images and the rest. (this site is not twitter related) If I was sloppy, that database would fall on it's face under that load. I have added in some caching where needed, so pages are rendered to disk at the expense of a php include of the data. I am in this thread to learn about the issue, but so far, getting to 64 bits should not be a barrier. Isn't this really a php issue anyway? Why can't php handle a 64 bit int in a 32 bit system? Maybe they need a bug report or a patch. MySql seems to handle 64 bit on my 32 bit test system here just fine.

Precisely. If you really want to turn the numbers into strings in PHP,
here are 2 workaround examples. Please note, I use PHP personally, so
I am not apathetic to this issue. There are programmatic ways of
dealing with it, and that's half the fun of programming, right?
Example 1 (cursor specific example);
?
/* normally use curl, but using file_get_contents for simplicity of example */
$json =
file_get_contents(http://twitter.com/followers/ids/barackobama.json?cursor=-1;);
echo $json;
$pattern = /\next_cursor\:([0-9]+),/;
$replace = \next_cursor\:\$1\,;
$new_json = preg_replace($pattern, $replace, $json);
$pattern = /\previous_cursor\:([0-9]+),/;
$replace = \previous_cursor\:\$1\,;
/* note $new_json in third parameter */
$new_json = preg_replace($pattern, $replace, $new_json);
echo $new_json;
var_dump(json_decode($new_json));
?
Example 2 (generalized json naked numbers example):
?
/* generic helper function to turn all number types in json into strings */
function stringify_json_numbers($json)
{
$pattern = /([:[]?)([-]?[0-9]+)([,}\]])/;
$replace = $1\$2\$3;
$new_json = preg_replace($pattern, $replace, $json);
return $new_json;
}
/* normally use curl, but using file_get_contents for simplicity of example */
$json =
file_get_contents(http://twitter.com/followers/ids/barackobama.json?cursor=-1;);
echo $json;
$new_json = stringify_json_numbers($json);
echo $new_json;
echo pre;
var_dump(json_decode($new_json));
echo /pre;
?
Can't we all just get along?

I think the point that some folks are trying to make is that forcing consumers of the API to use 64-bit machines is stifling innovation. Many Twitter apps start as pet projects hosted on a shared HostGator or other provider's server for nine bucks a month. That's how mine started way back. You don't have the option of editing php.ini or running on a 64-bit machine, unless you want to reduce your groceries per month and fork out more for a server. Dewald
[twitter-dev] Re: SERIOUS Problem With Cursors In JSON Followers/Friends Ids
Dewald sums it up great. I'm not affected by this issue but keeping the barrier of entry low is of high value. It sucks that some PHP installations have this issue, but if there's a good way to accomodate such a popular language then what's the harm? This brings up an issue though. I'm not in favor of changing the default int to a string. It's the default that's important. Adding in an override parameter isn't really anymore helpful than suggesting to parse the json once you get it. Except, the thought of pre-parsing json (no matter how simple) makes my stomach churn. Think about it from the perspective of a developer that's just starting with the API. What would trip them up? If there's a way to resolve that, then that should be a high priority. For me it's not a big deal since I've used it enough and know people in the API community and this group where I can get an answer. That's a luxury I didn't have when I started though. So far, two proposed solutions: * Abraham suggested an additional key (this is great because you see it in the response without having to know of an additional paramter) * I suggested an additional parameter which would return all values as a string (drawback is that this is a bit more hidden - not everyone RTM :( ) * Your suggestion here!

[twitter-dev] Re: SERIOUS Problem With Cursors In JSON Followers/Friends Ids
creat[ing] any large numeric values in the JSON output as strings could potentially break existing JSON-using applications, depending on the library they use and how they have typed the variable to receive the large numeric value. For http://twxlate.com, I use Google's GSON library (http://code.google.com/p/google-gson/), and, if I had typed my variables (actually, Java class fields) as int, Integer, long, or Long, then the change you suggest would break my code. Of course the code would also have been broken when the values exceeded 2**31 or 2**63. Anticipating this and also possibly non-numeric values, I typed the fields as Strings. So I have lucked out on the impact of Twitpocalylses. But others may not have been or be so lucky. On a higher plane, to my mind this is an issue of versioning in the API syntax. Twitter does not support explicit versioning (i.e., the inclusion of an API version parameter in API requests) as other RESTful interfaces do. For example, most Google API RESTful interface methods include a v= parameter to indicate which version of the method is being used. If twitter included this, then to receive large numeric values encoded as strings the requester could simply include, e.g., v=1.1, on the request. Given that twitter specified in advance that if you request version 1.1 responses then large numeric values would be encoded as strings, then any request made with v=1.1 would have known and had to be prepared to accept string encoded values. Without v=1.1, you would still get integer encoded values, and nothing would break. There have been, and I suspect will continue to be, changes to the API specification that were or will be not backward compatible without a version parameter, and for this reason I strongly urge twitter to adopt this mechanism for all non-backward compatible API changes. Version negotiation could also be done via HTTP headers, but I prefer method parameters. Comments expected and welcome.

until 65+ bit computing becomes standard, a lot of things will break (twitter included) when id's go past 64 bits. i hate to be a naysayer though, but the difference between 2^32 and 2^64 is, well, huge. i don't expect twitter id's to break 64 bits anytime soon, until at least far past twitter's usefulness (sorry, twitter...) i know this is akin to COBOL programmers in the fifties saying hmm, i wonder if we should concern ourselves with what will happen to our apps in the year 2000? and giving it no further thought, and i apologize, but i'm ok with that.

Clearly PHP_INT_MAX plays no role in json_decode. There must be some other mystical maximum number above which it represents the number as float in the decoded data.

That magical maximum number appears to be 1 (1.0E+12). So, for tweet ids we still have a bit of breathing space.

For reference, the PHP_INT_MAX on my 64-bit linux VM is: 9223372036854775807 and using json_decode on the next_cursor field of an ids list works just fine. I'm using PHP 5.2.10-0.dotdeb.1 (though PHP 5.2.11-0.dotdeb.1 is available) fwiw, -Chad On Thu, Sep 24, 2009 at 3:29 PM, Dewald Pretorius dpr...@gmail.com wrote: That magical maximum number appears to be 1 (1.0E+12).

Can someone explain this issue to me in more detail? How do I know my php can handle it? I'm running on an older PPC machine, which is 64 bit, but I have no idea if I built it as 64, I just supplied standard configure arguments. If php sees a 64 bit integer come in as JSON what happens on 32 bit? Does it just truncate it or completly ruin it's representation? Why can't it just be treated as a string?don't these ID's end up in a database, or maybe just passed as a URL argument? As a URL arg you pass to Twitter, so it will work fine. Any database can store a 64 bit int as a string, which gives your ability to get the string back to post to a URL. Can a 32 bit build of a database store 64 bit ints? That to me seems the bigger issue. I'm not seeing where there is a need for math on a 64 bit int ditectly in php. You get the value from JSON, treat it as a string, store that string, and use it for your lookups and sorts. Inneficient on lookups and storage, is that the core of this? What key aspect of this problem am I missing? -- Scott Iphone says hello.

If you want to consume the API with PHP, either run your stuff on a 64-bit machine, or scrape the raw JSON output and make it so that it works for you. That doesn't sound right.

from http://us2.php.net/json_decode: |In PHP = 5.1.6 trying to decode an integer value that's PHP_INT_MAX will result in an intger of PHP_INT_MAX. In PHP 5.2+ decoding an integer PHP_INT_MAX will cause a conversion to a float. Neither behaviour is perfect, capping at PHP_INT_MAX is marginally worse, but the float conversion loses precision. If you expect to deal with large numbers at all, let alone in JSON, ensure you're using a 64-bit system. -- my thoughts: if moving to a 64-bit system is not feasible and you aren't interesting in hacking the (php itself) source (num_as_string json_decode() patch at http://bugs.php.net/bug.php?id=46363), you could try xml or writing a quick-n-dirty twitter-specific decoder. other alternatives are looking at a hosting provider or paying someone (ahem) to patch your PHP instance plug(I do Linux only, not BSD or 'doze, but I've been doing Linux for a long time and I'm pretty good at it)/plug. thanks!

When retrieving ids with cursoring, and then doing a PHP json_decode on the data, the cursor value is converted to an exponentional number expression. For example: http://twitter.com/followers/ids/barackobama.json?cursor=-1 yields next_cursor:1314614526448841129 in the raw JSON data. After json_decode the value is converted to 1.31461452645E+18. I've tried both json_decode to an object and to an associative array and both give the same result. As you will notice, even if one were to typecast that number to float, there is still 8 digits missing, which would yield an invalid cursor. So, am I missing something glaringly obvious, or does someone have a solution to this issue? Dewald

All that Twitter needs to do to solve this problem is to build the JSON out with next_cursor and previous_cursor as string values.
