Copyleaks detects online plagiarism and checks content distribution. Use Copyleaks to find out if textual content is original and where it has been used before. This example in PHP shows how to integrate with the Copyleaks cloud to search for copyright infringement.

Copyleaks PHP SDK

Copyleaks SDK is a simple framework that allows you to scan text for plagiarism and detect content distribution online, using the Copyleaks plagiarism checker cloud.

Using Copyleaks SDK you can detect plagiarism in:

• Online content and webpages
• Local and cloud files (see supported files)
• Free text
• Images of text(using OCR) - scanning pictures with textual content (see supported files)

Installation

Integrate with the Copyleaks SDK in one of two options:

• Recommended: Use the Package Manager - Packagist.
  When integrating that way you will automatically be able to update the SDK to its latest version:

  composer require copyleaks/php-plagiarism-checker @dev
  

  Following that, in order to use the SDK, add this to your code:

  //copyleaks dependencies 
  include_once( __DIR__.'/vendor/copyleaks/php-plagiarism-checker/autoload.php');
  use Copyleaks\CopyleaksCloud;
  use Copyleaks\CopyleaksProcess;
  

• Download the code from this repository and add it to your project.

Register and Get Your API Key

To use the Copyleaks API you need to first have a Copyleaks account. The registration to Copyleaks takes a minute and is free of charge. Signup and confirm your account to finalize your registration.

You can generate your personal API key. Do so by entering your dashboard (Businesses dashboard/Academic dashboard/Websites dashboard), and under 'Access Keys' you will be able to see and generate your API keys.

For more information check out our API guide.

Examples

See example_asynchronous.php for an example using callbacks and example_synchronous.php for a synced example that update the status programatically.

Usage

To scan for plagiarism the URL: 'https://www.copyleaks.com'. All you have to do is to update the following two lines with your email and API key:

$email = 'Your-Email-Address-Here';
$apiKey = 'Your-API-Key-Here';

Add this additional header to get a completion callback:

$additionalHeaders = array($clConst['HTTP_CALLBACK'].': http://your.website.com/callbacks/' 

For testing purposes you can use http://requestb.in

Create a process using createByUrl:

$process  = $clCloud->createByURL('https://www.copyleaks.com',$additionalHeaders); 

Available create methods are: createByURL, createByFile, createByFiles, createByOCR and createByText.

If you don't want to use callbacks you can wait for the scan to complete:

while ($process->getStatus() != 100){
	sleep(2);              
}

And get the results:

$results = $process->getResult();
// Print the results
foreach ($results as $result) {
	echo $result;
}

Configuration

You can set specific headers:

$additionalHeaders = array(
  $clConst['SANDBOX_MODE_HEADER'], // Sandbox mode - Scan without consuming any credits and get back dummy results
  $clConst['HTTP_CALLBACK'].': http://your.website.com/callbacks/', # For a fast testing of callbacks option we recommend to use http://requestb.in
  $clConst['IN_PROGRESS_RESULT'].': http://your.website.com/callback/results/,
  $clConst['EMAIL_CALLBACK'].': [email protected]',
  $clConst['CLIENT_CUSTOM_PREFIX'].'name: some name'
  $clConst['PARTIAL_SCAN_HEADER'],
  $clConst['COMPARE_ONLY'] # Compare files in between - available only on createByFiles
  $clConst['IMPORT_FILE_TO_DATABASE'] # Import your file to our database only
  );

For more info about the optional headers see API Request Headers
