PHPCap

PHPCap is a PHP API (Application Programming Interface) for REDCap, that lets you:

• export/import/delete data in REDCap
• export/import/delete project information (e.g., field names and types) in REDCap

PHPCap makes accessing REDCap from a PHP program easier by providing:

• a high-level interface
• improved error checking

REDCap is a web application for building and managing online surveys and databases. For information about REDCap, please see http://www.project-redcap.org.

• A computer with PHP 5.6 or later installed, and PHP needs to have cURL and OpenSSL enabled.

$project = new RedCapProject($apiUrl, $apiToken);

# Print the project title
$projectInfo = $project->exportProjectInfo();
print "project title: ".$projectInfo['project_title']."\n";

# Print the first and last names for all records
