PHP - PPT to HTML

Using PHP to convert PPT to HTML

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 HTML 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 = "HTML";

$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.html";;
$endpoint = "https://sandbox.zamzar.com/v1/files/$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 HTML with PHP

There are a number of open source tools for creation of HTML files from a variety of different source file formats. Often the rendering of the outputted HTML file can be very heavyweight or difficult to edit, so it is worth reviewing the various different programs on offer to see which suits your needs. If you have a fairly simple source format such as a Microsoft Word document that is not too complex then you could consider using a tool such as Unoconv which converts between formats that OpenOffice supports and can output to HTML, the results however can be a little mixed if you have more complex documents.

Another option is to use another open source tool - Poppler. A number of developers have created PHP libraries that utilise Poppler for converting from PDF into HTML, so one option would be to convert the file into PDF then use a Poppler PHP library to convert that resulting PDF file into HTML - see PDF to HTML PHP Library using Poppler. Poppler is known to have some rendering issues, so it is certainly worth testing on a wide variety of files before deciding on this as a solution.

If you need a commercial solution with the benefit of the support that comes with that you could consider the Zamzar API. With a dedicated team on hand to help, 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.
