Why Optimize a Typecho Site?

As website traffic increases, performance becomes a critical factor in user experience. Typecho is a lightweight blogging system, and although it’s efficient by default, properly optimizing PHP code can further boost page speed and overall stability. This guide offers practical strategies focusing on caching, query optimization, static resource management, and memory control.

1. Implementing Redis Caching for Data

Caching is a powerful way to accelerate access times and reduce database load. Typecho can integrate with Redis to cache frequently accessed data, minimizing backend processing.

// Connect to Redis
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

// Check if cache exists
if ($redis->exists('data_cache')) {
    $data = $redis->get('data_cache');
} else {
    // Fetch data from database
    $data = $db->query('SELECT * FROM table');

    // Store data in cache
    $redis->set('data_cache', serialize($data));
}

// Use data
foreach ($data as $row) {
    // Process data
}

2. Optimize Database Queries

Slow database queries are a common performance bottleneck. Indexing, using efficient joins, and reducing query frequency are all effective ways to speed up data retrieval.

• Use Indexes: Index frequently queried fields to enhance search speed.

• Use Inner Joins: Simplify queries and reduce load.

• Batch Queries: Replace multiple queries with a single IN statement.

Below is a comparison between inefficient and optimized queries:

// Multiple queries (not recommended)
foreach ($ids as $id) {
    $row = $db->query('SELECT * FROM table WHERE id = '.$id);
    // Process data
}

// Batch query (recommended)
$ids = implode(',', $ids);
$rows = $db->query('SELECT * FROM table WHERE id IN ('.$ids.')');

foreach ($rows as $row) {
    // Process data
}

3. Optimize Static Resource Loading with Caching

Efficiently managing CSS/JS resources helps reduce HTTP requests and speeds up page loading. Techniques include compression, merging, and caching.

function load_css(){
    $css_file = 'style.css';
    $cache_file = md5($css_file).'.css';

    // Check if cache exists
    if(file_exists($cache_file)){
        include $cache_file;
    } else {
        ob_start();
        include $css_file;
        $content = ob_get_clean();

        // Compress CSS
        $content = compress_css($content);

        // Save cached file
        file_put_contents($cache_file, $content);

        // Output content
        echo $content;
    }
}

4. Prevent Memory Leaks in PHP

Memory leaks can lead to increasing memory usage over time, potentially crashing your server. Good coding habits and awareness of object handling help prevent such issues.

• Release Resources: Close database connections and file handlers when done.

• Avoid Circular References: Be cautious with objects that reference each other.

// Release resources properly
$db->close();

// Avoid circular references
class A {
    public $b;
}
class B {
    public $a;
}

$a = new A();
$b = new B();
$a->b = $b;
$b->a = $a;

Conclusion

Optimizing PHP in a Typecho-based website can significantly enhance performance and the overall user experience. With the right strategies—such as implementing caching, improving database queries, compressing resources, and managing memory—you can make your site faster, more responsive, and scalable for the future.
