get_temp_dir()
Determine a writable directory for temporary files.
Description
Function’s preference is the return value of sys_get_temp_dir(), followed by your PHP temporary upload directory, followed by WP_CONTENT_DIR, before finally defaulting to /tmp/
In the event that this function does not find a writable location, It may be overridden by the WP_TEMP_DIR constant in your wp-config.php file.
Return
(string) Writable temporary directory.
