{
private static $graphicsAPI;
public static function initialize()
{
switch (PHP_OS_FAMILY) {
case 'Windows':
self::$graphicsAPI = 'DirectX';
break;
case 'Linux':
self::$graphicsAPI = 'OpenGL';
break;
case 'Darwin':
self::$graphicsAPI = 'Metal';
break;
default:
self::$graphicsAPI = 'OpenGL';
}
self::applyPlatformSpecificConfig();
}
private static function applyPlatformSpecificConfig()
{
// Windows特定配置
if (self::$graphicsAPI === 'DirectX') {
Core::setConfigFlags(FLAG_MSAA_4X_HINT);
}
// macOS Metal优化
if (self::$graphicsAPI === 'Metal') {
Core::setConfigFlags(FLAG_VSYNC_HINT);
}
// Linux OpenGL配置
if (self::$graphicsAPI === 'OpenGL') {
Core::setConfigFlags(FLAG_WINDOW_RESIZABLE);
}
}
public static function getSupportedShaderFormats(): array
{
$formats = ['glsl'];
if (self::$graphicsAPI === 'DirectX') {
$formats[] = 'hlsl';
} elseif (self::$graphicsAPI === 'Metal') {
$formats[] = 'metal';
}
return $formats;
}
}
输入系统兼容性处理
class InputCompatibilityHandler
{
public static function normalizeKeyCodes(int $keyCode): int
{
// 跨平台键码映射
$keyMap = [
// Windows -> 标准键码映射
// Linux -> 标准键码映射
// macOS -> 标准键码映射
];
return $keyMap[$keyCode] ?? $keyCode;
}
public static function handleTouchInput(array $touchPoints): array
{
// 统一触摸输入处理
$normalizedPoints = [];
foreach ($touchPoints as $point) {
$normalizedPoints[] = [
'id' => $point['id'],
'x' => $point['x'],
'y' => $point['y'],
'pressure' => $point['pressure'] ?? 1.0
];
}
return $normalizedPoints;
}
}
性能监控与优化
跨平台性能基准测试
class PerformanceBenchmark
{
private array $metrics = [];
public function measureRenderPerformance(): array
{
$results = [];
// 2D渲染性能测试
$results['2d_rendering'] = $this->test2DRendering();
// 3D渲染性能测试
$results['3d_rendering'] = $this->test3DRendering();
// 纹理加载性能测试
$results['texture_loading'] = $this->testTextureLoadingPerformance();
return $results;
}
private function test2DRendering(): array
{
$startTime = microtime(true);
$frames = 0;
Core::initWindow(800, 600, "性能测试");
Core::setTargetFPS(0); // 无限制帧率
while ($frames < 1000) {
Core::beginDrawing();
Core::clearBackground(Utils::color(255, 255, 255));
// 绘制1000个矩形
for ($i = 0; $i < 1000; $i++) {
Shapes::drawRectangle(
rand(0, 800),
rand(0, 600),
10, 10,
Utils::color(rand(0, 255), rand(0, 255), rand(0, 255))
);
}
Core::endDrawing();
$frames++;
}
$endTime = microtime(true);
Core::closeWindow();
return [
'total_time' => $endTime - $startTime,
'frames' => $frames,
'fps' => $frames / ($endTime - $startTime)
];
}
}
测试结果分析与报告
兼容性评分系统
class CompatibilityScorer
{
public static function calculateScore(array $testResults): float
{
$totalTests = 0;
$passedTests = 0;
foreach ($testResults['tests'] as $category => $tests) {
foreach ($tests as $testResult) {
$totalTests++;
if ($testResult['success']) {
$passedTests++;
}
}
}
return $totalTests > 0 ? ($passedTests / $totalTests) * 100 : 0;
}
public static function generateCompatibilityReport(array $testResults): array
{
$score = self::calculateScore($testResults);
$platform = $testResults['platform'];
return [
'platform' => $platform['os'] . ' ' . $platform['architecture'],
'php_version' => $platform['php_version'],
'compatibility_score' => $score,
'grade' => self::getGrade($score),
'test_summary' => self::generateTestSummary($testResults['tests']),
'recommendations' => self::generateRecommendations($testResults['tests'])
];
}
private static function getGrade(float $score): string
{
if ($score >= 95) return 'A+ (优秀)';
if ($score >= 85) return 'A (良好)';
if ($score >= 75) return 'B (一般)';
if ($score >= 60) return 'C (需要改进)';
return 'D (不兼容)';
}
}
最佳实践与建议
跨平台开发准则
-
资源路径处理
// 错误的做法 $texturePath = "C:\\textures\\image.png"; // 正确的做法 $texturePath = DIRECTORY_SEPARATOR . "textures" . DIRECTORY_SEPARATOR . "image.png"; -
图形API抽象层
interface GraphicsRenderer { public function initialize(); public function render(); public function shutdown(); } class OpenGLRenderer implements GraphicsRenderer { // OpenGL具体实现 } class DirectXRenderer implements GraphicsRenderer { // DirectX具体实现 } -
输入系统标准化
class InputManager { public static function getKeyName(int $keyCode): string { // 跨平台键名映射 $keyNames = [ KEY_W => 'W', KEY_A => 'A', KEY_S => 'S', KEY_D => 'D' ]; return $keyNames[$keyCode] ?? 'Unknown'; } }
持续集成策略
结论
php-raylib的跨平台兼容性测试是一个系统工程，需要从图形渲染、输入处理、音频系统等多个维度进行全面验证。通过建立完善的测试工具链、自动化测试流水线和兼容性评分系统，可以确保库在不同平台下的稳定性和性能。
关键成功因素包括：
- 多平台测试环境的标准化配置
- 自动化测试用例的全面覆盖
- 实时性能监控和优化
