I am working on attendance application using PHP and MySQL, I want to automate the attendance process by getting all data from fingerprint devices directly and import them into MySQL database through PHP script.

I googled and found a script which uses PHP SOCKETS to retrieve data through device IP (Link):

$ cd your_repo_root/repo_name
$ git fetch origin
$ git checkout gh-pages

The problem is the data looks messy, not complete and there's a lot of decryption through library functions.

I also tried the CURL, but it's not working (Link):

$number="";
    for($i=1;$i<=100;$i++){
      $number.=($i.",");
    }
    $number=substr($number,0,strlen($number)-1);
    $url = "http://192.168.2.201/form/Download?uid=".$number."&sdate=2013-09-10&edate=2013-09-10";

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $server_output = curl_exec ($ch);

    curl_close ($ch);

    $data = array();
    $record = explode("\n",$server_output);
    foreach($record as $r){
      $r = str_replace("\t"," ",$r);
      $isi = explode(" ",$r);
      array_push($data, $isi);
    }

    print_r($data);

Is there's any other ways that I can get all the data from fingerprint through PHP, as the provider of the device doesn't provide any PHP SDK for it.

Fingerprint type: Granding

Available SDKs: C# and ASP.NET

    Well what type of api or interface *is* provided with the device? This question is probably too specific for SO – Steve Jan 20 '15 at 11:21
  • @Steve, they provided a C# and ASP.NET SDKs. – CairoCoder Jan 20 '15 at 11:22
  • @CairoCoder it's true that the question is too specific, but if you have a C#/ASP.NET SDK and you're running on a windows machine you can give a try to the dotnet class - http://php.net/manual/en/class.dotnet.php – Diogo Raminhos Jan 20 '15 at 11:32

    Do you have a link to the c# api documentation? I expect the simplest thing to do would be to write a small c# app that dumps the data into database or flatfile for simple retrieval via php. – Steve Jan 20 '15 at 11:39
  • Yes @Steve, I have a link: http://www.granding.com/CMS/Uploads/SDK_6.2.4.1_with_DEMO.rar – CairoCoder Jan 20 '15 at 11:52
  • @Whiteagle Will give it a try, but I don't have past experience with C# or ASP.NET – CairoCoder Jan 20 '15 at 11:53
  • It is indeed possible.Check out this solution PHP Web Biometric Authentication PACK found here https://jomutech.com/phpwebbiometricauthenticationlitepack/ You could also check out other examples of PHP Web Biometric Authentication and Integration at https://jomutech.com . Disclaimer:Some of the pictures for the said PHP Biometric Web Applications found in those links are mine. – Joseph Aug 12 '19 at 09:37

Handling the biometric machine through PHP is possible. There is an answer for a similar question in Quora:

Can we integrate bio-metric attendance system with php?

According to this, you can configure an internet URL where you can handle the attendance data.

    While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes. – Martin Evans Aug 30 '17 at 17:41
  • @kevin, your link points to the api documentation which helps to recording the attendance. There is another api link: https://www.quora.com/Can-we-integrate-bio-metric-attendance-system-with-php/answer/Otchathevan which talks about capturing a fingerprint from the client page. – Ravanan Nov 11 '18 at 15:35
  • The link from above comment is not accessible. https://youtu.be/w5QEQglRmK8 Check this video link which demonstrates integrating biometrics with PHP program – Ravanan Oct 01 '20 at 19:55

along with the granding fingerprint devices (zk7000) I faced similar difficulties, php scripts was not working for me. you can try bio-plugin that supports php integration and worked well in my system.
