redcap_info()
REDCap has a PHP function called redcap_info(), similar to phpinfo(), that can be called from anywhere within a REDCap page, plugin, or hook. Calling the redcap_info() function will automatically render a web page (when viewing the script in a web browser) that will display a table listing all PHP constants and variables that have been pre-defined by REDCap and are thus available for utilization in a hook or plugin. This provides plugin/hook developers with a head start by making known what resources are available that they may utilize in their code. The tables displayed below are the output of the redcap_info() function.
