PHP - PPT to JPG

Using PHP to convert PPT to JPG

Zamzar offers a simple file conversion API to convert files from your applications with support for 100's of formats. Below we have listed an example to convert a PPT file to JPG using PHP. We also support a variety of other programming languages.

If you have any questions check out our comprehensive FAQ which contains further information on how to use the API.

PHP Code Sample

Our example code assumes that you're using PHP 5.3 or newer.

To convert your first file with the Zamzar API, send an HTTP request to POST https://sandbox.zamzar.com/v1/jobs containing your source file, and the your desired target format. If the source file is on the web or in S3, send us the URL: the source file doesn't need to hit your servers.

<?php
$endpoint = "https://sandbox.zamzar.com/v1/jobs";
$apiKey = "GiVUYsF4A8ssq93FR48H";
$sourceFile = "https://s3.amazonaws.com/zamzar-samples/sample.ppt";
$targetFormat = "jpg";

$postData = array(
  "source_file" => $sourceFile,
  "target_format" => $targetFormat
);

$ch = curl_init(); // Init curl
curl_setopt($ch, CURLOPT_URL, $endpoint); // API endpoint
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return response as a string
curl_setopt($ch, CURLOPT_USERPWD, $apiKey . ":"); // Set the API key as the basic auth username
$body = curl_exec($ch);
curl_close($ch);

$response = json_decode($body, true);

echo "Response:\n---------\n";
print_r($response);

Your source file is now being converted. Send an HTTP request to GET https://sandbox.zamzar.com/v1/jobs/$jobId to check its progress. The response will also give you details about your converted file.

<?php
$jobID = 15;
$endpoint = "https://sandbox.zamzar.com/v1/jobs/$jobID";
$apiKey = "GiVUYsF4A8ssq93FR48H";

$ch = curl_init(); // Init curl
curl_setopt($ch, CURLOPT_URL, $endpoint); // API endpoint
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return response as a string
curl_setopt($ch, CURLOPT_USERPWD, $apiKey . ":"); // Set the API key as the basic auth username
$body = curl_exec($ch);
curl_close($ch);

$job = json_decode($body, true);

echo "Job:\n----\n";
print_r($job);

Once the status of your job is successful, your converted file is ready to download. Send an HTTP request to GET https://sandbox.zamzar.com/v1/file/$fileId/content to download it. We store your files for a day by default, and for longer on our paid plans.

<?php
$fileID = 3;
$localFilename = "converted.jpg";;
$endpoint = "https://sandbox.zamzar.com/v1/files/$fileID/content";
$apiKey = "GiVUYsF4A8ssq93FR48H";

$ch = curl_init(); // Init curl
curl_setopt($ch, CURLOPT_URL, $endpoint); // API endpoint
curl_setopt($ch, CURLOPT_USERPWD, $apiKey . ":"); // Set the API key as the basic auth username
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);

$fh = fopen($localFilename, "wb");
curl_setopt($ch, CURLOPT_FILE, $fh);

$body = curl_exec($ch);
curl_close($ch);

echo "File downloaded\n";

Using PPT with PHP

Powerpoint files can be manipulated through a number of open source tools. You could consider using the PHP Presentation open source software library which is written in pure PHP (and licensed under LGPL version 3). It supports both the reading and writing of Powerpoint files, but does have some limitations around rendering - for example losing styling in some cases. It is however actively updated so over time bugs and issues are being fixed.

Another option is to use LibreOffice Impress, this is an actively developed solution for reading and writing Powerpoint files, however it's automation API is limited in PHP. It does have some fairly well documented rendering issues too, for example with SmartArt presentations. Think carefully before using it if rendering is an important cog in your conversion needs, but as a low cost solution this might suffice.

If you need commercial software that renders as accurately as the native Microsoft Office tooling then you could consider using the Zamzar API. With a dedicated support team, code examples in many of the major languages including PHP, simple low cost conversion credits and support for direct import and export to S3, it may cover most of the use cases you require. Feel free to reach out to our support team with any questions or dip into the getting started guide in our docs.

Using JPG with PHP

You have a number of options when looking to convert JPG files using PHP and each of them have various pros and cons. You could consider using the GD PHP library which has quite extensive support for image processing and has a large number of online resources which you can use as a great reference guide when writing your code.

Another option is to use an open source tool such as ImageMagick, which is known as the "Swiss Army Knife" of image processing. It has a large number of configurable options and is fairly easily configurable through a handy object-oriented interface - see these examples. It also has extensive documentation and there is a wide body of online support in forums should you hit technical issues.

If you'd prefer to use commercial software with dedicated support from developers and a high quality rendering engine you could consider using the Zamzar API. With code examples in many of the major languages including PHP, simple low cost conversion credits and support for direct import and export to S3, it may cover most of the use cases you have.
