Please read this document setup a PHP error handler that shows solutions on a Web page for known errors.

Hitilafu - Beautiful PHP Error Handler

A developer-friendly error page renderer inspired by Laravel Ignition, but standalone with no dependencies.

Features

• Beautiful, modern error pages with dark/light theme
• Stack trace with code context
• Intelligent solution suggestions
• Request and environment information
• Responsive design
• Syntax-highlighted code blocks

Installation

composer require wepesi/hitilafu

Usage

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

use Wepesi\Hitilafu\Hitilafu;

// Register the error handler
Hitilafu::register()
    ->setAppName('My Awesome App')
    ->setTheme('dark'); // or 'light'

Custom Solutions

Add custom solutions for specific error patterns:

Hitilafu::register()
    ->addSolution(
        'mysqli_connect',
        'MySQL Connection Issue',
        'Make sure your MySQL server is running and credentials are correct.',
        [
            ['text' => 'MySQL Docs', 'url' => 'https://dev.mysql.com/doc/']
        ]
    );

custom solutions are used based on the application implementation like (plugins, component, models, controllers, ...)

Important: Syntax Error Limitations

Why Syntax Errors Can't Be Caught

Syntax errors (parse errors) occur during PHP's compilation phase, BEFORE your code executes. This means:

1. Same file syntax errors: Cannot be caught because PHP parses the entire file before running it
2. Included file syntax errors: CAN be caught via `handleShutdown()` when using `include` or `require`

Example

This WON'T work (syntax error in main file):

<?php
Hitilafu::register(); // Handler registered

echo "test"  // Syntax error - handler never runs because file fails to parse

This WILL work (syntax error in included file):

<?php
// index.php
Hitilafu::register(); // Handler registered successfully

include 'bad_file.php'; // If bad_file.php has syntax errors, handler catches it

Testing Syntax Error Handling

To test syntax error you can check the example file where the is a list of custom example already tested.

<?php
Hitilafu::register();

// This will trigger the error handler
include 'example.php'; // Contains syntax errors

Error Types Handled

• Runtime Errors: Division by zero, undefined variables, etc.
• Exceptions: Uncaught exceptions
• Fatal Errors: Memory exhaustion, maximum execution time
• Parse Errors: In included files (NOT in the main file)
• Warnings & Notices: Converted to ErrorException

Built-in Solutions

The handler provides intelligent solutions for common errors:

• File not found
• Database connection errors
• Undefined variables/functions
• Class not found
• Memory exhausted
• Permission denied
• And more...
