Does the user you are logged into pass this test?
set filename to whatever file you want then: >> opens a file append (open file, move file pointer to the very end of the file), if the file does not exist it tries to create the file and opens it for write at position zero. Any of these steps can give the error you got.
What do you get? Note: Are you creating new file?? ... you need write privilege to the directory, otherwise just write privilege to the file itself and a minimum of execute on the path.

dio_open
DIO_OPEN(3) 1 DIO_OPEN(3)dio_open - Opens a file (creating it if necessary) at a lower level than the C library input/ouput stream functions allow.
SYNOPSIS
resource dio_open (string $filename, int $flags, [int $mode])
DESCRIPTION dio_open(3) opens a file and returns a new file descriptor for it.
PARAMETERS
o $filename
- The pathname of the file to open.
o $flags
- The $flags parameter is a bitwise-ORed value comprising flags from the following list. This value must include one of O_RDONLY,
O_WRONLY, or O_RDWR. Additionally, it may include any combination of the other flags from this list.
o O_RDONLY - opens the file for read access.
o O_WRONLY - opens the file for write access.
o O_RDWR - opens the file for both reading and writing.
o O_CREAT - creates the file, if it doesn't already exist.
o O_EXCL - if both O_CREAT and O_EXCL are set and the file already exists, dio_open(3) will fail.
o O_TRUNC - if the file exists and is opened for write access, the file will be truncated to zero length.
o O_APPEND - write operations write data at the end of the file.
o O_NONBLOCK - sets non blocking mode.
o O_NOCTTY - prevent the OS from assigning the opened file as the process's controlling terminal when opening a TTY device
file.
o $mode
- If $flags contains O_CREAT, $mode will set the permissions of the file (creation permissions). $mode is required for correct
operation when O_CREAT is specified in $flags and is ignored otherwise. The actual permissions assigned to the created file will
be affected by the process's umask setting as per usual.
RETURN VALUES
A file descriptor or FALSE on error.
EXAMPLES
Example #1
Opening a file descriptor
<?php
$fd = dio_open('/dev/ttyS0', O_RDWR | O_NOCTTY | O_NONBLOCK);
dio_close($fd);
?>
