$fileData = file_get_contents('path/to/file.jpg'); // Read the file's contents $fileSize = filesize('path/to/file.jpg'); // Get the file size in bytes $fileType = mime_content_type('path/to/file.jpg'); // Get the file's MIME type CFile::SaveForDB( $fileData, // The file's contents array( 'MODULE_ID' => 'my_module', // Your module name 'HEIGHT' => $height, // Optional: the file's height in pixels 'WIDTH' => $width, // Optional: the file's width in pixels 'FILE_SIZE' => $fileSize, // The file's size in bytes 'CONTENT_TYPE' => $fileType, // The file's MIME type 'ORIGINAL_NAME' => 'file.jpg', // The file's original name ), 'my_images', // The name of the table to store the file in true, // Optional: delete the file from the file system after it's saved to the database );In this example, we're using CFile SaveForDB to save a JPEG image file to a database. The file is read from the file system using `file_get_contents()`, and its size and MIME type are determined using `filesize()` and `mime_content_type()`, respectively. We then pass this data to CFile::SaveForDB along with some optional metadata, including the file's height and width if available, the name of our module, the original name of the file, and the name of the database table to store the file in. Finally, we set the `deleteFile` parameter to `true` to delete the file from the file system after it's saved to the database. CFile SaveForDB is part of the Bitrix framework, which is an open-source PHP web application framework designed for high-performance websites. It is included in the Bitrix API library, which contains a range of functions and classes for developing web applications using Bitrix.
