BetterPhpInfo - Enhanced PHP Information Display

Version: 1.0 Author: Thomas Traunter | PHPLABOR | www.phplabor.de License: MIT License Description: A modern, visually appealing alternative to phpinfo() with search

         functionality and improved organization using Bootstrap 5.

OVERVIEW

BetterPhpInfo is a PHP class that provides three main ways to access PHP configuration information:

1. render() - Complete HTML standalone page with Bootstrap UI
2. search() - Filter results and return as array
3. get() - Get specific configuration value directly

INSTALLATION

1. Include the main class file in your project: require_once 'BetterPhpInfo.php';
2. Create an instance: $betterPhpInfo = new BetterPhpInfo();
3. Use any of the three methods as needed.

USAGE METHODS

Method 1: Standalone Page (render)

Basic usage (no authentication):

$betterPhpInfo = new BetterPhpInfo();
$betterPhpInfo->render();

With authentication:

$betterPhpInfo = new BetterPhpInfo();
$betterPhpInfo->render('your_username', 'your_password');

Parameters: - username (optional): Required username for access - password (optional): Required password for access

Security: If authentication fails, the login form is shown again without any error messages (for security reasons).

Method 2: Search Configuration (search)

Search for specific settings:

$results = $betterPhpInfo->search('memory');
$results = $betterPhpInfo->search('mysql');
$results = $betterPhpInfo->search('upload');

Returns: Array with matching configuration values organized by category.

Example result structure:

Array(
    [Category Name] => Array(
        [config_key] => Array(
            [local] => 'value',
            [master] => 'master_value'
        )
    )
)

Method 3: Get Specific Value (get)

Get individual configuration values using the exact key names:

$memoryLimit = $betterPhpInfo->get('memory_limit');
$phpVersion = $betterPhpInfo->get('PHP Version');
$uploadMax = $betterPhpInfo->get('upload_max_filesize');

Note: Key names may vary by PHP version. Use search() first to find exact names.

Returns: The local (currently active) value of the configuration setting, or null if not found.

Method 4: Get All Available Keys

Get list of all available configuration keys:

$allKeys = $betterPhpInfo->getAvailableKeys();

Returns: Array of all configuration keys that can be used with get() method.

FINDING AND USING CONFIGURATION VALUES

How to work with configuration values:

1. FIND THE CORRECT KEY NAME: Use search() to find the exact key name you need:

   $results = $betterPhpInfo->search('memory');

   This will show all keys containing 'memory' with their exact names.

2. GET THE VALUE: Use the exact key name from search results:

   $value = $betterPhpInfo->get('memory_limit');

   Key names vary by PHP version and configuration - always search first.

MASTER VS LOCAL VALUES: - MASTER: Original value from php.ini configuration file - LOCAL: Currently active value (may be changed at runtime)

When values differ: - The setting was modified using ini_set(), .htaccess, or scripts - get() always returns the LOCAL value (what's currently active) - search() shows both values when they differ

Example: - php.ini has: memory_limit = 128M (Master) - Script runs: ini_set('memory_limit', '256M'); (changes Local) - Result: Master = 128M, Local = 256M - get('memory_limit') returns '256M' (the active value)

FEATURES

Standalone Page Features: - Modern Bootstrap 5 responsive design - Live search with highlighting - Collapsible categories with icons - Statistics overview - Clean formatting of boolean values (enabled/disabled) - 50/50 column layout for better readability - Optional username/password authentication

Search Features: - Case-insensitive search - Searches both keys and values - Returns organized results by category - Preserves all configuration data structure

Get Features: - Direct access to any configuration value - Accepts exact key names as shown in search results - Fast lookup by key name - Returns null for non-existent keys - Returns local (currently active) values

AVAILABLE EXAMPLES

1. example_standalone_no_login.php - Simple standalone page without authentication - Perfect for development environments
2. example_standalone_with_login.php - Standalone page with username/password protection - Configure credentials in the file - Secure login without error messages
3. example_search.php - Demonstrates search functionality with console output - Simple formatted text output - Shows multiple search examples
4. example_get.php - Shows how to get specific values with console output - Lists common configuration keys organized by category - Simple formatted text output

QUICK START FOR STANDALONE USAGE

For a simple standalone PHP info page, you can also add this directly at the bottom of the BetterPhpInfo.php class file:

// Uncomment these lines for direct standalone usage:
// $betterPhpInfo = new BetterPhpInfo();
// $betterPhpInfo->render();

Then simply access the BetterPhpInfo.php file in your browser.

AUTHENTICATION DETAILS

Login System: - Optional authentication for render() method - Pass username and password as parameters - Secure form-based authentication - No error messages for failed attempts (security feature) - Session-based (form POST method)

Security Features: - No information disclosure on failed login - Clean login interface - Form-based authentication - No timing attack vulnerabilities

CONFIGURATION KEY REFERENCE

Key names in PHP configuration can vary between versions and setups. Examples of possible variations:

• "memory_limit" (standard)
• "PHP Version 8.2.29" (version-specific)
• "Shared memory model" (with spaces)
• "opcache.enable" (with dots)

RECOMMENDED WORKFLOW: 1. Use search() to locate configuration: $results = $betterPhpInfo->search('opcache'); 2. Examine results to find exact key name 3. Use exact key with get(): $value = $betterPhpInfo->get('opcache.enable');

This approach works reliably regardless of PHP version or key name variations.

COMMON USE CASES

Development Environment: - Use standalone without authentication for local development - Quick overview of PHP configuration - Search for specific settings during debugging

Production Monitoring: - Use with authentication for production servers - Programmatic access via get() for monitoring scripts - Search functionality for troubleshooting

Integration: - Embed search results in existing applications - Extract specific values for application logic - Monitor critical PHP settings programmatically

REQUIREMENTS

• PHP 7.4 or higher
• DOMDocument extension (typically included)
• Web server for standalone usage
• Bootstrap 5 (loaded via CDN in examples)

TROUBLESHOOTING

Issue: Blank page when using render() Solution: Check PHP error logs, ensure DOMDocument is available

Issue: Authentication not working Solution: Verify username/password are set correctly, check POST data

Issue: get() returns null for existing setting Solution: Use search() first to find the exact key name, then use that exact name

Issue: Search returns no results Solution: Try broader search terms, search is case-insensitive

BROWSER COMPATIBILITY

Standalone page supports: - Chrome 60+ - Firefox 60+ - Safari 12+ - Edge 79+

Features used: - CSS Grid and Flexbox - Bootstrap 5 components - Modern JavaScript (ES6+)

CUSTOMIZATION

The class can be extended for custom functionality: - Override getIconForCategory() for custom icons - Modify CSS in render() for custom styling - Extend search() for custom filtering logic - Add custom authentication methods
