(PHP Extension) Download File from Dropbox into a String VariableDemonstrates how to download a file from Dropbox directly into a string variable.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // A Dropbox access token should have been previously obtained. // Dropbox access tokens do not expire. // See Dropbox Access Token. $rest = new CkRest(); // Connect to Dropbox $success = $rest->Connect('content.dropboxapi.com',443,true,true); if ($success != true) { print $rest->lastErrorText() .
