## **Overview**

[Open Presentations in PHP](/slides/php-java/open-presentation/) described how to use the [Presentation](https://reference.aspose.com/slides/php-java/aspose.slides/presentation/) class to open a presentation. This article explains how to create and save presentations. The [Presentation](https://reference.aspose.com/slides/php-java/aspose.slides/presentation/) class contains a presentation’s contents. Whether you’re creating a presentation from scratch or modifying an existing one, you’ll want to save it when you’re finished. With Aspose.Slides for PHP, you can save to a **file** or **stream**. This article explains the different ways to save a presentation.

## **Save Presentations to Files**

Save a presentation to a file by calling the [Presentation](https://reference.aspose.com/slides/php-java/aspose.slides/presentation/) class’s `save` method. Pass the file name and save format to the method. The following example show how to save a presentation with Aspose.Slides.

```php
// Instantiate the Presentation class that represents a presentation file.
$presentation = new Presentation();
try {
    // Do some work here...

    // Save the presentation to a file.
    $presentation->save("Output.pptx", SaveFormat::Pptx);
} finally {
    $presentation->dispose();
}
```

## **Save Presentations to Streams**

You can save a presentation to a stream by passing an output stream to the [Presentation](https://reference.aspose.com/slides/php-java/aspose.slides/presentation/) class’s `save` method. A presentation can be written to many stream types. In the example below, we create a new presentation and save it to a file stream.

```php
// Instantiate the Presentation class that represents a presentation file.
$presentation = new Presentation();
try {
    $fileStream = new Java("java.io.FileOutputStream", "Output.pptx");
    try {
        // Save the presentation to the stream.
        $presentation->save($fileStream, SaveFormat::Pptx);
    } finally {
        $fileStream->close();
    }
} finally {
    $presentation->dispose();
}
```

## **Save Presentations with a Predefined View Type**

Aspose.Slides lets you set the initial view that PowerPoint uses when the generated presentation opens through the [ViewProperties](https://reference.aspose.com/slides/php-java/aspose.slides/viewproperties/) class. Use the [setLastView](https://reference.aspose.com/slides/php-java/aspose.slides/viewproperties/#setLastView) method with a value from the [ViewType](https://reference.aspose.com/slides/php-java/aspose.slides/viewtype/) enumeration.

```php
$presentation = new Presentation();
try {
    $presentation->getViewProperties()->setLastView(ViewType::SlideMasterView);
    $presentation->save("SlideMasterView.pptx", SaveFormat::Pptx);
} finally {
    $presentation->dispose();
}
```

## **Save Presentations in the Strict Office Open XML Format**

Aspose.Slides lets you save a presentation in the Strict Office Open XML format. Use the [PptxOptions](https://reference.aspose.com/slides/php-java/aspose.slides/pptxoptions/) class and set its conformance property when saving. If you set [Conformance.Iso29500_2008_Strict](https://reference.aspose.com/slides/php-java/aspose.slides/conformance/#Iso29500_2008_Strict), the output file is saved in the Strict Office Open XML format.

The example below creates a presentation and saves it in the Strict Office Open XML format.

```php
$options = new PptxOptions();
$options->setConformance(Conformance::Iso29500_2008_Strict);

// Instantiate the Presentation class that represents a presentation file.
$presentation = new Presentation();
try {
    // Save the presentation in the Strict Office Open XML format.
    $presentation->save("StrictOfficeOpenXml.pptx", SaveFormat::Pptx, $options);
} finally {
    $presentation->dispose();
}
```

## **Save Presentations in Office Open XML Format in Zip64 Mode**

An Office Open XML file is a ZIP archive that imposes 4 GB (2^32 bytes) limits on the uncompressed size of any file, the compressed size of any file, and the total size of the archive, and it also limits the archive to 65,535 (2^16-1) files. ZIP64 format extensions raise these limits to 2^64.

The [PptxOptions.setZip64Mode](https://reference.aspose.com/slides/php-java/aspose.slides/pptxoptions/#setZip64Mode) method lets you choose when to use ZIP64 format extensions when saving an Office Open XML file.

This method can be used with the following modes:

- [IfNecessary](https://reference.aspose.com/slides/php-java/aspose.slides/zip64mode/#IfNecessary) uses ZIP64 format extensions only if the presentation exceeds the limitations above. This is the default mode.
- [Never](https://reference.aspose.com/slides/php-java/aspose.slides/zip64mode/#Never) never uses ZIP64 format extensions.
- [Always](https://reference.aspose.com/slides/php-java/aspose.slides/zip64mode/#Always) always uses ZIP64 format extensions.

The following code demonstrates how to save a presentation as PPTX with ZIP64 format extensions enabled:

```php
$pptxOptions = new PptxOptions();
$pptxOptions->setZip64Mode(Zip64Mode::Always);

$presentation = new Presentation("Sample.pptx");
try {
    $presentation->save("OutputZip64.pptx", SaveFormat::Pptx, $pptxOptions);
} finally {
    $presentation->dispose();
}
```

{{% alert title="NOTE" color="warning" %}}

When you save with [Zip64Mode.Never](https://reference.aspose.com/slides/php-java/aspose.slides/zip64mode/#Never), a [PptxException](https://reference.aspose.com/slides/php-java/aspose.slides/pptxexception/) is thrown if the presentation cannot be saved in ZIP32 format.

{{% /alert %}}

## **Save Presentations without Refreshing the Thumbnail**

The [PptxOptions.setRefreshThumbnail](https://reference.aspose.com/slides/php-java/aspose.slides/pptxoptions/#setRefreshThumbnail) method controls thumbnail generation when saving a presentation to PPTX:

- If set to `true`, the thumbnail is refreshed during save. This is the default.
- If set to `false`, the current thumbnail is preserved. If the presentation has no thumbnail, none is generated.

In the code below, the presentation is saved to PPTX without refreshing its thumbnail.

```php
$pptxOptions = new PptxOptions();
$pptxOptions->setRefreshThumbnail(false);

$presentation = new Presentation("Sample.pptx");
try {
    $presentation->save("Output.pptx", SaveFormat::Pptx, $pptxOptions);
}
finally {
    $presentation->dispose();
}
```

{{% alert title="Info" color="info" %}}

This option helps reduce the time required to save a presentation in PPTX format.

## **Save Progress Updates in Percentage**

Save-progress reporting is configured via the [setProgressCallback](https://reference.aspose.com/slides/php-java/aspose.slides/saveoptions/#setProgressCallback) method on [SaveOptions](https://reference.aspose.com/slides/php-java/aspose.slides/saveoptions/) and its subclasses. Provide a Java proxy that implements the [IProgressCallback](https://reference.aspose.com/slides/java/com.aspose.slides/iprogresscallback/) interface; during export, the callback receives periodic percentage updates.

The following code snippets show how to use `IProgressCallback`.

```php
class ExportProgressHandler {
    function reporting($progressValue) {
        // Use the progress percentage value here.
        $progress = java("java.lang.Double")->valueOf($progressValue)->intValue();
        echo($progress . "% of the file has been converted.");
    }
}

$progressHandler = java_closure(new ExportProgressHandler(), null, java("com.aspose.slides.IProgressCallback"));

$saveOptions = new PdfOptions();
$saveOptions->setProgressCallback($progressHandler);

$presentation = new Presentation("Sample.pptx");
try {
    $presentation->save("Output.pdf", SaveFormat::Pdf, $saveOptions);
} finally {
    $presentation->dispose();
}
```

Aspose has developed a [free PowerPoint Splitter app](https://products.aspose.app/slides/splitter) using its own API. The app lets you split a presentation into multiple files by saving selected slides as new PPTX or PPT files.

## **FAQ**

### Is "fast save" (incremental save) supported so only changes are written?

No. Saving creates the full target file each time; incremental "fast save" isn’t supported.

### Is it thread-safe to save the same Presentation instance from multiple threads?

No. A [Presentation](https://reference.aspose.com/slides/php-java/aspose.slides/presentation/) instance [isn’t thread-safe](/slides/php-java/multithreading/); save it from a single thread.

### What happens to hyperlinks and externally linked files when saving?

[Hyperlinks](/slides/php-java/manage-hyperlinks/) are preserved. External linked files (e.g., videos via relative paths) aren’t copied automatically—ensure the referenced paths remain accessible.

### Can I set/save document metadata (Author, Title, Company, Date)?

Yes. Standard [document properties](/slides/php-java/presentation-properties/) are supported and will be written to the file on save.
