PHP资源编译与部署优化

PHP资源编译与部署优化

PHP项目的编译和部署涉及多个方面。从Composer优化到OPcache配置，今天说说PHP项目的编译和部署优化。

Composer优化。

```bash
# 优化自动加载
composer dump-autoload -o

# 安装生产依赖
composer install --no-dev --optimize-autoloader

# 分析依赖
composer why monolog/monolog
composer outdated
composer audit
```

OPcache配置。

```ini
opcache.enable=1
opcache.memory_consumption=256
opcache.interned_strings_buffer=16
opcache.max_accelerated_files=20000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.validate_timestamps=0

; JIT配置
opcache.jit=tracing
opcache.jit_buffer_size=100M
```

部署脚本。

```php
class DeployOptimizer
{
private string $projectDir;

public function __construct(string $projectDir)
{
$this->projectDir = rtrim($projectDir, '/');
}

public function optimize(): void
{
$this->composerOptimize();
$this->cacheConfig();
$this->warmCache();
$this->setPermissions();
}

private function composerOptimize(): void
{
chdir($this->projectDir);
exec('composer install --no-dev --optimize-autoloader 2>&1');
}

private function cacheConfig(): void
{
// 框架配置缓存
if (file_exists("{$this->projectDir}/artisan")) {
exec('php artisan config:cache');
exec('php artisan route:cache');
exec('php artisan view:cache');
}
}

private function warmCache(): void
{
// 预热常用类
$classes = ['App\Models\User', 'App\Models\Order', 'App\Services\UserService'];
foreach ($classes as $class) {
if (class_exists($class)) {
echo "预加载: $class\n";
}
}
}

private function setPermissions(): void
{
exec("chmod -R 775 {$this->projectDir}/storage");
exec("chmod -R 775 {$this->projectDir}/bootstrap/cache");
}
}
?>

部署检查。

```php
class DeployCheck
{
public static function run(): array
{
$checks = [];

// PHP版本
$checks['php_version'] = version_compare(PHP_VERSION, '8.0', '>=');

// 必要扩展
$requiredExts = ['pdo_mysql', 'mbstring', 'json', 'curl', 'gd', 'opcache'];
$checks['extensions'] = [];
foreach ($requiredExts as $ext) {
$checks['extensions'][$ext] = extension_loaded($ext);
}

// Composer
$checks['composer_optimized'] = self::isComposerOptimized();

// OPcache
$status = opcache_get_status(false);
$checks['opcache_enabled'] = $status !== false;
$checks['jit_enabled'] = ($status['jit']['enabled'] ?? false);

// 文件权限
$checks['storage_writable'] = is_writable(__DIR__ . '/storage');

return $checks;
}

private static function isComposerOptimized(): bool
{
$lock = __DIR__ . '/composer.lock';
$vendor = __DIR__ . '/vendor';
return file_exists($lock) && file_exists($vendor);
}
}
?>

部署后的配置验证。

```php
function verifyDeployment(): void
{
$checks = DeployCheck::run();
$passed = true;

foreach ($checks as $name => $result) {
if (is_array($result)) {
foreach ($result as $key => $value) {
$status = $value ? '✓' : '✗';
echo "{$key}: {$status}\n";
if (!$value) $passed = false;
}
} else {
$status = $result ? '✓' : '✗';
echo "{$name}: {$status}\n";
if (!$result) $passed = false;
}
}

exit($passed ? 0 : 1);
}
?>

部署优化是上线前的必要步骤。Composer优化减少自动加载开销，OPcache/JIT提升运行性能，配置缓存减少文件解析。部署后验证确保环境配置正确。
