> 使用 Aspose.Slides 在 PHP 中绘制和控制连接器：添加、路由、重新路由、设置连接点、箭头和样式，以链接 PPT、PPTX 和 ODP 中的形状。

演示如何使用 **Aspose.Slides for PHP via Java** 将形状通过连接器连接并更改其目标。

## **添加连接器**

在幻灯片的两个点之间插入一个连接器形状。

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

        $connector = $slide->Shapes->addConnector(ShapeType::BentConnector2, 0, 0, 100, 100);

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

## **访问连接器**

检索添加到幻灯片的第一个连接器形状。

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

        // 访问幻灯片上的第一个连接器。
        $firstConnector = null;
        $shapeCount = java_values($slide->getShapes()->size());
        for ($index = 0; $index < $shapeCount; $index++) {
            $shape = $slide->getShapes()->get_Item($index);
            if (java_instanceof($shape, new JavaClass("com.aspose.slides.Connector"))) {
                $firstConnector = $shape;
                break;
            }
        }
    } finally {
        $presentation->dispose();
    }
}
```

## **删除连接器**

从幻灯片中删除连接器。

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

        // 假设幻灯片上的第一个形状是连接器。
        $connector = $slide->getShapes()->get_Item(0);

        $slide->getShapes()->remove($connector);

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

## **重新连接形状**

通过分配起始和结束目标，将连接器附加到两个形状上。

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

        $shape1 = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 0, 0, 50, 50);
        $shape2 = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 100, 50, 50);
        $connector = $slide->getShapes()->addConnector(ShapeType::BentConnector2, 0, 0, 100, 100);

        $connector->setStartShapeConnectedTo($shape1);
        $connector->setEndShapeConnectedTo($shape2);

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