展示如何使用 **Aspose.Slides for PHP via Java** 建立簡單的動畫並管理其順序。

## **新增動畫**

建立一個矩形形狀，並套用在點擊時觸發的淡入效果。

```php
function addAnimation() {
    $presentation = new Presentation();
    try {
        $slide = $presentation->getSlides()->get_Item(0);
        $shape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 50, 50, 100, 100);

        // 淡入效果。
        $slide->getTimeline()->getMainSequence()->addEffect($shape, EffectType::Fade, EffectSubtype::None, EffectTriggerType::OnClick);

        $presentation->save("animation.pptx", SaveFormat::Pptx);
    } finally {
        $presentation->dispose();
    }
}
```

## **存取動畫**

從投影片時間軸中取得第一個動畫效果。

```php
function accessAnimation() {
    $presentation = new Presentation("animation.pptx");
    try {
        $slide = $presentation->getSlides()->get_Item(0);

        // 取得第一個動畫效果。
        $effect = $slide->getTimeline()->getMainSequence()->get_Item(0);
    } finally {
        $presentation->dispose();
    }
}
```

## **移除動畫**

從序列中移除動畫效果。

```php
function removeAnimation() {
    $presentation = new Presentation("animation.pptx");
    try {
        $slide = $presentation->getSlides()->get_Item(0);
        $effect = $slide->getTimeline()->getMainSequence()->get_Item(0);

        // 移除效果。
        $slide->getTimeline()->getMainSequence()->remove($effect);

        $presentation->save("animation_removed.pptx", SaveFormat::Pptx);
    } finally {
        $presentation->dispose();
    }
}
```

## **動畫序列**

新增多個效果，並示範動畫發生的順序。

```php
function sequenceAnimations() {
    $presentation = new Presentation();
    try {
        $slide = $presentation->getSlides()->get_Item(0);

        $shape1 = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 50, 50, 100, 100);
        $shape2 = $slide->getShapes()->addAutoShape(ShapeType::Ellipse, 200, 50, 100, 100);

        $sequence = $slide->getTimeline()->getMainSequence();
        $sequence->addEffect($shape1, EffectType::Fly, EffectSubtype::Bottom, EffectTriggerType::OnClick);
        $sequence->addEffect($shape2, EffectType::Fly, EffectSubtype::Bottom, EffectTriggerType::OnClick);

        $presentation->save("animation_sequence.pptx", SaveFormat::Pptx);
    } finally {
        $presentation->dispose();
    }
}
```
