extract device and browser info from above

Assistant

Here’s the extracted device and browser information from the given user agent string:

### **Device Information:**
– **Operating System (OS):** Windows 10 (Windows NT 10.0)
– **Architecture:** 64-bit (Win64; x64)

### **Browser Information:**
– **Browser Name:** Chrome
– **Browser Version:** 131.0.0.0
– **Browser Engine:** WebKit (AppleWebKit/537.36)

Let me know if you need this formatted differently or additional analysis.

Here’s a PHP script to extract device and browser information from the user agent string:

<?php
// User Agent string
$userAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36";

// Extract information using regex
preg_match('/Windows NT ([d.]+);.*(Win64|WOW64|x64)/', $userAgent, $osMatches);
preg_match('/(Chrome)/([d.]+)/', $userAgent, $browserMatches);

// Device Information
$os = isset($osMatches[1]) ? 'Windows ' . $osMatches[1] : 'Unknown OS';
$architecture = isset($osMatches[2]) ? $osMatches[2] : 'Unknown Architecture';

// Browser Information
$browser = isset($browserMatches[1]) ? $browserMatches[1] : 'Unknown Browser';
$browserVersion = isset($browserMatches[2]) ? $browserMatches[2] : 'Unknown Version';

// Output the results
echo "Operating System: $osn";
echo "Architecture: $architecturen";
echo "Browser: $browsern";
echo "Browser Version: $browserVersionn";
?>

### Output:
When run with the given user agent, this script will output:

Operating System: Windows 10.0
Architecture: x64
Browser: Chrome
Browser Version: 131.0.0.0

You can adjust the regex patterns to match other potential user agent formats. Let me know if you need enhancements!

for all type of browser and devices

To handle all types of browsers and devices, you can use a comprehensive library like **`get_browser()`** (built-in in PHP) or a third-party library like **`MobileDetect`**. Here’s a solution using both approaches:

—

### **1. Using `get_browser()` (PHP Built-in Function)**

<?php
// User Agent string
$userAgent = $_SERVER['HTTP_USER_AGENT'] ?? '';

// Configure the `browscap` in php.ini if not already done (or provide an alternative ini file)
ini_set('browscap', '/path/to/php_browscap.ini');

// Get browser and device information
$browserInfo = get_browser($userAgent, true);

// Extract data
$os = $browserInfo['platform'] ?? 'Unknown OS';
$architecture = strpos($userAgent, 'Win64') !== false || strpos($userAgent, 'x64') !== false ? '64-bit' : '32-bit';
$browser = $browserInfo['browser'] ?? 'Unknown Browser';
$browserVersion = $browserInfo['version'] ?? 'Unknown Version';
$deviceType = $browserInfo['device_type'] ?? 'Unknown Device';

// Output the results
echo "Operating System: $osn";
echo "Architecture: $architecturen";
echo "Browser: $browsern";
echo "Browser Version: $browserVersionn";
echo "Device Type: $deviceTypen";
?>

**Note:**
– Ensure you have the `browscap` file properly configured in `php.ini`.
– Example configuration: `browscap = /path/to/php_browscap.ini`.

### **2. Using `MobileDetect` Library**

Install **`MobileDetect`** via Composer:

composer require mobiledetect/mobiledetectlib

Then use the following script:

<?php
require_once 'vendor/autoload.php';

use DetectionMobileDetect;

// Initialize MobileDetect
$detect = new MobileDetect();

// User Agent
$userAgent = $_SERVER['HTTP_USER_AGENT'] ?? '';

// Check device type
$deviceType = $detect->isMobile() ? 'Mobile' : ($detect->isTablet() ? 'Tablet' : 'Desktop');

// Get operating system (basic)
$os = 'Unknown OS';
if ($detect->isAndroidOS()) {
    $os = 'Android';
} elseif ($detect->isiOS()) {
    $os = 'iOS';
} elseif (preg_match('/Windows NT ([d.]+)/', $userAgent, $matches)) {
    $os = 'Windows ' . $matches[1];
} elseif (strpos($userAgent, 'Macintosh') !== false) {
    $os = 'MacOS';
}

// Extract browser information
preg_match('/(Chrome|Firefox|Safari|Opera|Edge|MSIE|Trident)/?([d.]+)/', $userAgent, $browserMatches);
$browser = $browserMatches[1] ?? 'Unknown Browser';
$browserVersion = $browserMatches[2] ?? 'Unknown Version';

// Architecture detection
$architecture = strpos($userAgent, 'x64') !== false || strpos($userAgent, 'Win64') !== false ? '64-bit' : '32-bit';

// Output results
echo "Device Type: $deviceTypen";
echo "Operating System: $osn";
echo "Architecture: $architecturen";
echo "Browser: $browsern";
echo "Browser Version: $browserVersionn";
?>

### **Key Features:**
1. **Device Type:** Identifies `Mobile`, `Tablet`, or `Desktop`.
2. **OS:** Detects major operating systems like Windows, macOS, Android, and iOS.
3. **Browser:** Matches popular browsers (`Chrome`, `Firefox`, `Safari`, etc.) with their versions.
4. **Architecture:** Determines `64-bit` or `32-bit` architecture.

### **Output Example (for your User Agent):**

Device Type: Desktop
Operating System: Windows 10.0
Architecture: 64-bit
Browser: Chrome
Browser Version: 131.0.0.0
