|
|
## File Structure
|
|
|
|
### Before (Duplicated Code)
|
|
```

|
header01.php (400 lines) ─┐
|
|
├─ 280 lines DUPLICATE
|
|
header02.php (400 lines) ─┘
|
|
┌─ 120 lines DIFFERENT
|
|
|
|
Total: 800 lines | Duplication: 70%
|
|
```
|
|
|
|
### After (Consolidated)
|
|
```
|
|
header.php (300 lines) ┐
|
|
header_config.php (100 lines) ├─ Zero duplication
|
|
┘
|
|
|
|

## Code Reduction Examples
|
|
|
|
### Example 1: Logo Implementation
|
|
|
|
**Before (Two Files):**
|
|
```php
|
|
// header01.php
|
|
<img src="assets/images/logos/logo.png" style="width:200px;" alt="Logo">
|
|
|
|
// header02.php
|
|
<img src="assets/images/logos/logo-two.png" style="width:200px;" alt="Logo">
|
|
```
|
|
|
|
**After (Single File with Config):**
|
|
```php
|
|
// header.php
|
|
<img src="<?php echo $config['logo_image']; ?>" style="<?php echo $config['logo_width']; ?>" alt="Logo">
|
|
|
|
// header_config.php
|
|
'01' => ['logo_image' => 'assets/images/logos/logo.png'],
|
|
'02' => ['logo_image' => 'assets/images/logos/logo-two.png'],
|
|
```
|
|
|
|
**Lines Saved:** 2 lines → 1 line logic (config-driven)
|
|
|
|
### Example 2: Welcome Text Color
|
|
|
|
**Before (Two Files):**
|
|
```php
|
|
// header01.php
|
|
<span style="color: #fff;">Welcome, <?php echo $_SESSION['first_name']; ?></span>
|
|
|
|
// header02.php
|
|
<span style="color: #111111;">Welcome, <?php echo $_SESSION['first_name']; ?></span>
|
|
```
|
|
|
|
**After (Single File with Config):**
|
|
```php
|
|
// header.php
|
|
<span style="color: <?php echo $config['welcome_text_color']; ?>;">Welcome, <?php echo $_SESSION['first_name']; ?></span>
|
|
|
|
// header_config.php
|
|
'01' => ['welcome_text_color' => '#fff'],
|
|
'02' => ['welcome_text_color' => '#111111'],
|
|
```
|
|
|
|
**Lines Saved:** 2 files with duplication → 1 line logic (config-driven)
|
|
|
|
### Example 3: Conditional Menus
|
|
|
|
**Before (Two Files):**
|
|
```php
|
|
// header01.php
|
|
<?php if ($is_member): ?>
|
|
<li class="dropdown"><a href="#">Members Area</a>
|
|
<ul><li><a href="#">Coming Soon!</a></li></ul>
|
|
</li>
|
|
<?php endif; ?>
|
|
|
|
// header02.php
|
|
<!-- No Members Area Menu -->
|
|
<!-- (Menu logic duplicated, just removed) -->
|
|
```
|
|
|
|
**After (Single File with Config):**
|
|
```php
|
|
// header.php
|
|
<?php if ($config['member_area_menu'] && $is_member): ?>
|
|
<li class="dropdown"><a href="#">Members Area</a>
|
|
<ul><li><a href="#">Coming Soon!</a></li></ul>
|
|
</li>
|
|
<?php endif; ?>
|
|
|
|
// header_config.php
|
|
'01' => ['member_area_menu' => true],
|
|
'02' => ['member_area_menu' => false],
|
|
```
|
|
|
|
**Lines Saved:** 2 implementations → 1 implementation (config-driven)
|
|
|
|
### Example 4: Security Headers
|
|
|
|
**Before (Two Files):**
|
|
```php
|
|
// header01.php
|
|
if (empty($_SERVER['HTTPS']) || $_SERVER['HTTPS'] === 'off') {
|
|
header('Location: https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'], true, 301);
|
|
exit;
|
|
}
|
|
header('Strict-Transport-Security: max-age=31536000; includeSubDomains; preload');
|
|
header('X-Content-Type-Options: nosniff');
|
|
// ... 4 more header() calls
|
|
|
|
// header02.php
|
|
// No security headers (omitted entirely)
|
|
```
|
|
|
|
**After (Single File with Config):**
|
|
```php
|
|
// header.php
|
|
if ($config['include_security_headers']) {
|
|
if (empty($_SERVER['HTTPS']) || $_SERVER['HTTPS'] === 'off') {
|
|
header('Location: https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'], true, 301);
|
|
exit;
|
|
}
|
|
header('Strict-Transport-Security: max-age=31536000; includeSubDomains; preload');
|
|
// ...
|
|
}
|
|
|
|
// header_config.php
|
|
'01' => ['include_security_headers' => true],
|
|
'02' => ['include_security_headers' => false],
|
|
```
|
|
|
|
**Lines Saved:** 2 complete implementations → 1 implementation (config-driven)
|
|

## Trips Menu Comparison
|
|
|
|
### Variant 01: Full Submenu
|
|
```php
|
|
<li><a href="trips.php">Trips</a>
|
|
<ul>
|
|
<li><a href="tour-list.html">Tour List</a></li>
|
|
<li><a href="tour-grid.html">Tour Grid</a></li>

|
```
|
|
|
|
### Variant 02: Simplified Menu
|
|
```php
|
|
<li><a href="trips.php">Trips</a></li>
|
|
```
|
|
|
|
### Consolidated: Single Code Block
|
|
```php
|
|
<?php if ($config['trip_submenu']): ?>
|
|
<li><a href="trips.php">Trips</a>
|
|
<ul>
|
|
<li><a href="tour-list.html">Tour List</a></li>
|
|
<li><a href="tour-grid.html">Tour Grid</a></li>
|
|
<li><a href="tour-sidebar.html">Tour Sidebar</a></li>
|

|
</ul>
|
|
</li>
|
|
<?php else: ?>

|
<li><a href="trips.php">Trips</a></li>
|
|
<?php endif; ?>
|
|
```
|
|
|

|
|
|
|
## Shadow Style Comparison
|
|
|
|
### Variant 01: Simple Shadow
|
|
```css
|
|
box-shadow: 0px 8px 16px rgba(0, 0, 0, 0.1);
|
|
```
|
|
**Effect:** Subtle depth, light glow
|
|
|
|
### Variant 02: Enhanced Shadow
|
|
```css
|
|
box-shadow: 2px 2px 5px 1px rgba(0, 0, 0, 0.1),
|
|
-2px 0px 5px 1px rgba(0, 0, 0, 0.1);
|
|
```
|
|
**Effect:** Double shadow with directional emphasis
|
|
|
|
### Consolidated:
|
|
```php
|
|
// header_config.php
|
|
'01' => ['shadow_style' => '0px 8px 16px rgba(0, 0, 0, 0.1)'],
|
|
'02' => ['shadow_style' => '2px 2px 5px 1px rgba(0, 0, 0, 0.1), -2px 0px 5px 1px rgba(0, 0, 0, 0.1)'],
|
|
|
|
// header.php
|
|
box-shadow: <?php echo $config['shadow_style']; ?>;
|
|
```
|
|
|
|
---
|
|
|
|
## CSS File Handling
|
|
|
|
### Variant 01 (Minimal Extra CSS)
|
|
```php
|
|
'extra_css_files' => [
|
|
'header_css.css',
|
|
],
|
|
'style_css_version' => '?v=1',
|
|
```
|
|
|
|
### Variant 02 (Extended CSS)
|
|
```php
|
|
'extra_css_files' => [
|
|
'https://fonts.googleapis.com/icon?family=Material+Icons',
|
|
'assets/css/jquery-ui.min.css',
|
|
'https://cdn.jsdelivr.net/npm/aos@2.3.4/dist/aos.css',
|
|
],
|
|
'style_css_version' => '',
|
|
'extra_styles' => true,
|
|
```
|
|
|
|
### Consolidated Loading:
|
|
```php
|
|
<?php foreach ($config['extra_css_files'] as $css_file): ?>
|
|
<link rel="stylesheet" href="<?php echo $css_file; ?>">
|
|
<?php endforeach; ?>
|
|
|
|
<link rel="stylesheet" href="assets/css/style_new.css<?php echo $config['style_css_version']; ?>">
|
|
```
|
|
|
|
---
|
|
|
|
## Page Setup Comparison
|
|
|
|
### Old Way (Two Different Files)
|
|
```php
|
|
// Homepage
|
|
<?php require_once('header01.php'); ?>
|
|
|
|
// Trip details page
|
|
<?php require_once('header02.php'); ?>
|
|
```
|
|
|
|
### New Way (Single File, Config-Driven)
|
|
```php
|
|
// Homepage
|
|
<?php define('HEADER_VARIANT', '01'); require_once('header.php'); ?>
|
|
|
|
// Trip details page
|
|
<?php define('HEADER_VARIANT', '02'); require_once('header.php'); ?>
|
|
```
|
|
|
|

|
|
|
|
## Maintenance Workflow
|
|
|
|
### Updating a Feature
|
|
|
|
**Before (Two Files - Must Edit Both):**
|
|
```bash
|
|
1. Edit header01.php nav menu
|
|
2. Edit header02.php nav menu
|
|
3. Test variant 1
|
|
4. Test variant 2
|
|
5. Risk: Forgetting to sync one file
|
|
```
|
|
|
|
**After (One File - Edit Once):**
|
|
```bash
|
|
1. Edit header.php nav logic
|
|
2. Test variant 1
|
|
3. Test variant 2
|
|
4. Done - always in sync
|
|
```
