How to convert an HTML Document to PNG Array in PHP

Today’s goal is pretty straightforward: to use PHP to render an HTML document, then export it as a series of PNG images. Want to know a secret? I know how to get this done instantly, with almost no work involved. How about I show you.

Kicking things off: client installation.

composer require cloudmersive/cloudmersive_document_convert_api_client

Following that is our function call:

<?php
require_once(__DIR__ . '/vendor/autoload.php');
// Configure API key authorization: Apikey
$config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('Apikey', 'YOUR_API_KEY');
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// $config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKeyPrefix('Apikey', 'Bearer');
$apiInstance = new Swagger\Client\Api\ConvertDocumentApi(
// If you want use custom http client, pass your client which implements `GuzzleHttp\ClientInterface`.
// This is optional, `GuzzleHttp\Client` will be used as default.
new GuzzleHttp\Client(),
$config
);
$input_file = "/path/to/file"; // \SplFileObject | Input file to perform the operation on.
try {
$result = $apiInstance->convertDocumentHtmlToPng($input_file);
print_r($result);
} catch (Exception $e) {
echo 'Exception when calling ConvertDocumentApi->convertDocumentHtmlToPng: ', $e->getMessage(), PHP_EOL;
}
?>

Whew! Already done. APIs make everything a breeze, don’t they. This same client contains numerous other functions, such as more format conversions as well as document editing and template application.
