🚀 Simplify ZKTeco Biometric Device Integration in PHP — No SDK Needed

Working with ZKTeco biometric attendance devices can be frustrating.

Most developers struggle with SDKs that are Windows-only, hard to configure, or poorly documented.

That’s why I built jmrashed/zkteco —

an open-source PHP library that lets you connect directly to any ZKTeco device via TCP/IP and manage data seamlessly.

💡 What This Library Does

This package gives PHP developers a simple, clean API to communicate with ZKTeco devices —

no proprietary SDKs or Windows dependencies required.

You can easily:

✅ Connect to your device using IP and port

✅ Retrieve attendance logs

✅ Add, update, or delete users

✅ Clear attendance data

✅ Restart the device remotely

All using pure PHP, compatible with Laravel, CodeIgniter, or standalone PHP apps.

🧠 Quick Start

Install via Composer:

composer require jmrashed/zkteco

Example Usage:

use jmrashed\Zkteco\Lib\ZKTeco;

$zk = new ZKTeco('192.168.1.201');

if ($zk->connect()) {
    $attendance = $zk->getAttendance();
    print_r($attendance);
    $zk->disconnect();
}

That’s it — you’ve just pulled attendance logs directly from your ZKTeco device 🎯

📊 Current Stats

📦 3,136+ installs on Packagist
⭐ 30+ stars on GitHub
🍴 11 forks
🐛 8 active issues (community-driven improvements ongoing)

Already used in HRM, ERP, and attendance SaaS systems across multiple companies.

⚙️ Why This Matters

ZKTeco integration is a critical feature for enterprise and HR software —
but SDK limitations often slow developers down.

This library bridges that gap — enabling faster, cross-platform, and cloud-ready attendance solutions in PHP.

🚀 Building a Production-Ready PHP REST API Framework (Open Source)

Md Rasheduzzaman — Tue, 21 Oct 2025 04:37:01 +0000

After building and managing 25+ enterprise applications (ERP, HRM, CRM, LMS, SaaS), I realized most PHP frameworks are powerful but heavy for small, API-only or microservice projects.

So, I decided to build a custom, production-ready REST API framework in raw PHP — clean, lightweight, and fully modular — now open-sourced on GitHub! 🎉

⚙️ Why I Built This

I wanted complete control over every layer: routing, middleware, authentication, and performance.

I needed something faster and leaner than Laravel for internal APIs and microservices.

I wanted to learn deeply how an API framework works under the hood — HTTP handling, dependency injection, error management, and versioning.

🧩 Framework Highlights

✅ Lightweight & Fast – built on raw PHP 8+, PSR-4 autoloading
✅ JWT Authentication – secure token-based access
✅ Clean Modular Structure – controllers, routes, middleware
✅ Built-in CLI & Job Queue System
✅ Debug Mode – track queries, memory, and response time
✅ API Versioning Support
✅ Error Handling, CORS, and Rate Limiting
✅ Ready for Docker & Production

🏗 Folder Structure Example
app/
├── core/
├── controllers/
├── middleware/
├── models/
├── routes/
├── storage/
public/
└── index.php

This structure keeps everything modular, testable, and scalable.

Let’s make this the go-to starting point for developers who want to build fast, clean, production-ready APIs with PHP!

Why does the First Flutter app take so long?

Md Rasheduzzaman — Thu, 29 Sep 2022 19:15:02 +0000

When we build the Flutter application the first time, it will take more time. It is because Flutter developed the device-specific IPA or APK file. So, the Xcode and Gradle are used for building the file, taking more time.

What are access modifiers in C++?

Md Rasheduzzaman — Sat, 03 Sep 2022 16:43:39 +0000

One of the main features of object-oriented programming languages such as C++ is data hiding. Data hiding refers to restricting access to data members of a class. This is to prevent other functions and classes from tampering with the class data.

You use access modifiers to define accessibility for the class members. It defines how to access the members of the class outside the class scope.

There are three types of access modifiers:

Private
Public
Protected

What is the difference between C and C++?

Md Rasheduzzaman — Sat, 03 Sep 2022 16:31:57 +0000

C and C++ are programming languages that are used for developing applications, games, database systems, operating systems, and more. While both C and C++ may sound similar, their features and usage are different.

C is a procedure-oriented programming language
It follows a top-down approach
C doesn’t support function or operator overloading
C language doesn’t support virtual and friend function
C language has 32 keywords

C++

C++ is a partially object-oriented programming language
It follows a bottom-up approach
C++ supports function as well as function overloading
C++ language supports both virtual and friend functions.
C++ language contains 52 keywords

C++ header

in C++

Md Rasheduzzaman — Sat, 03 Sep 2022 15:33:25 +0000

It is basically a header file that includes every standard library.

People do focus more on finding the algorithm to solve a problem than on software engineering.

✔ In contests, using this file is a good idea, when you want to reduce the time wasted doing chores; especially when your rank is time sensitive.

✔ This also reduces all the chores of writing all the necessary header files.

✔ You don’t have to remember all the STL of GNU C++ for every function you use.

𝘿𝙞𝙨𝙖𝙙𝙫𝙖𝙣𝙩𝙖𝙜𝙚𝙨 𝙤𝙛 𝙗𝙞𝙩𝙨/𝙨𝙩𝙙 𝙞𝙣 𝘾++

✘ bits/stdc++.h is a non-standard header file of GNU C++ library. So, if you try to compile your code with some compiler other than GCC it might fail.

✘ Using it would include a lot of unnecessary stuff and increase compilation time.

✘ This header file is not part of the C++ standard and is, therefore, non-portable, and should be avoided.
