Notes:

• The sys_get_temp_dir() function attempts to return the default temporary directory path to the operating system.
• The location of temporary directories may vary across operating systems.
• The returned directory path does not contain a slash (/).
• If the temporary directory path cannot be obtained, the function returns FALSE.

suggestion:

• When you need to create a temporary file or directory, using the sys_get_temp_dir() function ensures compatibility on different operating systems.
• When using the returned temporary directory path, it is best to manually add slashes (/) to ensure the correctness of the path.
