How can PHP usage be optimized for better performance?

To optimize PHP usage for better performance, consider using opcode caching, minimizing database queries, enabling gzip compression, and utilizing PHP accelerators like APC or OPcache. 

// Enable opcode caching
// Add the following lines to your php.ini file
opcache.enable=1
opcache.enable_cli=1
opcache.save_comments=1

// Minimize database queries
// Use prepared statements and avoid unnecessary queries
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");
$stmt->execute(['id' => $id]);
$user = $stmt->fetch();

// Enable gzip compression
// Add the following lines to your .htaccess file
<IfModule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/html
</IfModule>

// Utilize PHP accelerators like APC or OPcache
// Install and configure the accelerator in your PHP environment
