Basic PHP file to read the API

Hi, I saw this site and the API and though i would write a script to use it.

I have tried to comment is well as I can. Hopefully people can make use of this.

<?php

function checkspammers($input,$inputtype='ip'){
    //Load the file, and implode the array.
    $xml = implode('',file("http://www.stopforumspam.com/api?".$inputtype."=".$input));
    
    //Start new xml parser.
    $p = xml_parser_create();
    
    //Get the xml into an array
    xml_parse_into_struct($p, $xml, $vals, $index);
    
    //Free some memory by clearing the xml parser
    xml_parser_free($p);
    
    //We don't need $index or the $xml any more
    unset($index,$xml);
    
    
    //Prepare the return array
    $return = array();
    
    //Now we are going to make the aray useable
    foreach($vals as $array){
        //If it's the opening array we can do it slightly differnetly
        if($array['type'] == 'open'){
            //Just get weather it was sucess or not.
            $return[$array['tag']] = $array['attributes']['SUCCESS'];
        }elseif($array['type'] == 'complete'){
            //Else just get the value
            $return[$array['tag']] = $array['value'];
        }
    }
    
    //Save a bit mroe memory by clearing the vals array
    unset($vals);
    
    //Now make time into a unix timestamp
    if($return['LASTSEEN']){
        //Sepparate the timestamp into the time and the date
        $time = explode(' ',$return['LASTSEEN']);
        //Sepparate the date
        $date = explode("-",$time[0]);
        //Sepparate the time
        $time = explode("-",$time[0]);
        
        //Now make the time, note we times by 1 to remove leading zeros, if we don't then php cansometimes use teh octal system instead of decimal.
        $return['UNIXLASTSEEN'] = gmmktime($time[0]*1,$time[1]*1,$time[2]*1,$date[1]*1,$date[2]*1,$date[0]*1);
    }
    
    //RESPONCE would be better as booleen, not a string
    if($return['RESPONCE'] == 'true'){ $return['RESPONCE'] = true; }else{ $return['RESPONCE'] = false; }
    
    //Now return our array.
    return $return;
}

//Example function to check in ip
function isaspammer($ip){
    //Get the xml results as an array from teh function above
    $result = checkspammers($ip);
    //Is he reported?
    if($result['FREQUENCY'] > 0){
        //He is a spammer
        return true;
    }else{
        //He is not reported as a spammer
        return false;
    }
}

//Demo of example function
//Is he a spammer
if(isaspammer($_GET['ip'])){
    //Yes
    echo $_GET['ip'].' is a spammer.';
}else{
    //No
    echo $_GET['ip'].' is ok.';
}

?>

Edit: At a quick glance at the rest of the forum some people want to know how to only get recently reported people.

$result = checkspammers($ip);
if($result['FREQUENCY'] > 0 && (time() - $result['UNIXLASTSEEN']) < (3600 * 24 * 365)){
//We have a spammer active in the last 365 days
}

Edit2: I have an smf forum, this is what I did to implement this checker at registration.

./sources/Register.php - Line 142
Add $_SERVER to the global.

Just below that add the following code

    // Is he a reported spammer?
    if(isaspammer($_SERVER['REMOTE_ADDR'])){
        die("You are a reported spammer, please contact an admin regarding registration");
    }

And at the top of that file, around line 43, just before the Register() function starts, add the isaspammer() and checkspammers() functions listed above. That should stop anyone listed as a spammer from registering

yh, sorry I didn't check what version of php the functions were for. I'm guessing that most people have version 5 though? The only person I know how doesn't has the beta of version 6.

Re: Basic PHP file to read the API

There are actually still thousands of people still using PHP4, either through choice, or because their hosting co doesn't want to upgrade for whatever reason.

ok, probably a stupid question but why not upgrade? Are there advantages to php4?

Re: Basic PHP file to read the API

Many people regard php5 to be badly broken and a waste of time.

Re: Basic PHP file to read the API

There are so many hosting companies out there that would break a serious amount of their customers sites if they upgraded to php5.  So many in fact that I doubt any of them would do an in place upgrade

Re: Basic PHP file to read the API

What they need to do is make PHP5 a concurrent PHP version with 4 at it's core, and simply use <?php5 ?> as a preamble to alert the interpereter that the code is PHP5. This way nothing breaks, new functions are still available.

Re: Basic PHP file to read the API

I know this is an old thread, but this is a small and useful script and I would like to thank MadnessRed for sharing it. I am planning to use it with lastseen and frequency.

Is there any way to rewrite this script to do ip and email lookups (with only one call to SFS)?

Re: Basic PHP file to read the API

Hi, yes It should be possible, the api does support multiple inputs. I'll edit the code.

Re: Basic PHP file to read the API

hi,

Well i think this script needs

$input = htmlspecialchars($input);
$inputtype = htmlspecialchars($inputtype);

to close the door to possible XSS holes

Re: Basic PHP file to read the API

doesnt completely close the doors, for that people should really look at decoding utf8 and using htmlpurifier

Thank you very much for sharing your knowledge MadnessRed, I really appreciate it smile

Not everyone is a php experts so this is a really useful script. Maybe one of the admins could put a link to this post from the SFS "mods & plugins" page?

Re: Basic PHP file to read the API

Here's some other PHP code - I wrote this before I saw yours here. But since I finished it and it seems to work I thought I would chuck it up here as well since it doesn't hurt to have more examples...

    // Form an url to stopforumspam.com, set the flag for JSON format,
    // and add parameters for username= , ip= , and email=
    
    $url = "http://www.stopforumspam.com/api?f=json";
    
    $url .= "&username=" . urlencode($logon);
    
    $ip = $_SERVER['REMOTE_ADDR'];
    if ( $ip != "127.0.0.1" )
        $url .= "&ip=" . $ip;
        
    if ( isset($email) && $email != "none" )
        $url .= "&email=" . urlencode($email);
    
    $data = file_get_contents( $url );
    $result = json_decode( $data, true );

    // The result will be an array structured like this:
    //
    //[
    //    'success' => 1
    //    'username' => [ 'frequency' = x, 'appears' = 0 ]
    //    'email' => [ 'frequency' = x, 'appears' = 0 ]
    //    'ip' => [ 'frequency' = x, 'appears' = 0 ]
    //]
    //
    // the 'appears' field will be set to 1 or true if it appears in the spam database.
    
    // First check for overall success of the query.
    if ( is_array($result) && isset($result['success']) && $result['success'] )
    {
        // Now see if username, email, or ip appears in the database.
    
        function appears( $val, $result )
        {
            if ( isset( $result[$val] ) && is_array( $result[$val] ) && isset( $result[$val]['appears'] ) )
                return $result[$val]['appears'];
            
            return false;
        }
        
        if ( appears( 'username', $result )
            || appears( 'email', $result )
            || appears( 'ip', $result ) )
        {
            // If we get to here, the username, email, or ip has been recorded as being
            // a known spammer in the stopforumspam database.
            
            // So exit or whatever you want - don't allow the registration to proceed.

Re: Basic PHP file to read the API

You might want to add some basic error checking to that, to check if the JSON is malformed (in case of, say, packet loss or connection interruption) or if no data was returned by file_get_contents().

e.g. after file_get_contents and json_decode()

if($data !== NULL && $result === NULL)
{
    // error handling goeth here, invalid json detected
}

As an alternative though, there's this:
https://github.com/damianb/OpenFlame-Fr … y/JSON.php
Requires PHP 5.3.0+, but it provides full error handling for JSON strings.  Just pass it the string from file_get_contents and wrap in a try/catch block (the json decode uses the php-internal class RuntimeException).
It'll also tell you the reason the JSON decode failed in the exception message.

Re: Basic PHP file to read the API

If json_decode() fails, it won't return an array value, right?

So the test for is_array() shouldn't pass if json_decode() failed... It will only look at the result if json_decode() returned an array value, and that array has a 'success' value set in it.

But certainly more error handling code wouldn't hurt!

Just caught my first spam registration with this, I am thrilled! smile

Re: Basic PHP file to read the API

<?php
// Encode the data.
$json = json_encode(
    array(
        1 => array(
            'English' => array(
                'One',
                'January'
            ),
            'French' => array(
                'Une',
                'Janvier'
            )
        )
    )
);

// Define the errors.
$json_errors = array(
    JSON_ERROR_NONE => 'No error has occurred',
    JSON_ERROR_DEPTH => 'The maximum stack depth has been exceeded',
    JSON_ERROR_CTRL_CHAR => 'Control character error, possibly incorrectly encoded',
    JSON_ERROR_SYNTAX => 'Syntax error',
);

// Show the errors for different depths.
foreach(range(4, 3, -1) as $depth) {
    var_dump(json_decode($json, True, $depth));
    echo 'Last error : ', $json_errors[json_last_error()], PHP_EOL, PHP_EOL;
    }
?>

Obsidian, you have made a whole PHP library for SFS.

How can this be used on a generic site to check email and ip against the SFS database?

Maybe you can post a "quick start manual" here (or include it in the library), so that it is more easy for new beginners to PHP to use your library?

I can't, at the moment.  I'm writing the library for PHP 5.3+ at the moment, most of the codebase has been shredded to pieces.

The previous version in development, 0.3.0-dev is here though: https://github.com/damianb/SFSIntegration/tree/master

There's an example of it here: https://github.com/damianb/SFSIntegrati … xample.php

But, again, I'm rewriting it to make it more efficient and a bit easier to work with.  It'll be a while.
