File::generate_file_id │ public static │ WC 1.0

Generate a public ID for a log file based on its properties.

The file ID is the basename of the file without the hash part. It allows us to identify a file without revealing its full name in the filesystem, so that it's difficult to access the file directly with an HTTP request.

Method of the class: File{}

No Hooks.

Returns

String.

Usage

$result = File::generate_file_id( $source, ?int $rotation, $created ): string;
$source(string) (required)
The source of the log entries contained in the file.
?int $rotation
.
Default: null
$created(int)
The date the file was created, as a Unix timestamp.
