Function introduction:

The tempnam() functionis used to create a file with a unique file name.

tempnam ( string $dir , string $prefix ) : string

Create a file with a unique file name in the specified directory. If the directory does not exist, tempnam() generates a file in the system temporary directory and returns its filename.

The parameter dir indicates the directory in which the temporary file name will be created, and prefix indicates the prefix of the temporary file.

Note: Windows only uses the first three characters of the prefix.

The return value returns the new temporary file name, and returns FALSE on error.
