Where $manifest – path to manifest file or stored_file:
$manifest contains: stored_file Object ( [fs:stored_file:private] => file_storage Object ( [filedir:file_storage:private] => /var/www/mymoodledata/filedir [trashdir:file_storage:private] => /var/www/mymoodledata/trashdir [tempdir:file_storage:private] => /var/www/mymoodledata/temp/filestorage [dirpermissions:file_storage:private] => 511 [filepermissions:file_storage:private] => 438 [unoconvformats:file_storage:private] => ) [file_record:stored_file:private] => stdClass Object ( [id] => 1750 [contenthash] => 8353842d3fb4694026181524e59a6be2ae6e3cf3 [pathnamehash] => 7ba30b18aae3d442cd64f8b55e816cdf121c8710 [contextid] => 110 [component] => mod_scorm [filearea] => content [itemid] => 0 [filepath] => / [filename] => imsmanifest.xml [userid] => [filesize] => 12353 [mimetype] => application/xml [status] => 0 [source] => [author] => [license] => [timecreated] => 1472648288 [timemodified] => 1472648288 [sortorder] => 0 [referencefileid] => [repositoryid] => [reference] => [referencelastsync] => ) [filedir:stored_file:private] => /var/www/mymoodledata/filedir [repository:stored_file:private] => )
