Constants

MODE_APPEND_READ_WRITE  = 'a+b'
Open for reading and writing; place the file pointer at the end of the file. If the file does not exist, attempt to create it.
MODE_APPEND_WRITE  = 'ab'
Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it.
MODE_CREATE_READ_WRITE  = 'x+b'
Create and open for reading and writing; place the file pointer at the beginning of the file. If the file already exists, the fopen() call with fail by returning false and generating an error of level E_WARNING. If the file does not exist, attempt to create it. This is equivalent to specifying O_EXCL | O_CREAT flags for the underlying open(2) system call.
MODE_CREATE_WRITE  = 'xb'
Create and open for writing only; place the file pointer at the beginning of the file. If the file already exits, the fopen() call with fail by returning false and generating an error of level E_WARNING. If the file does not exist, attempt to create it. This is equivalent to specifying O_EXCL | O_CREAT flags for the underlying open(2) system call.
MODE_READ  = 'rb'
Open for reading only; place the file pointer at the beginning of the file.
MODE_READ_WRITE  = 'r+b'
Open for reading and writing; place the file pointer at the beginning of the file.
MODE_TRUNCATE_READ_WRITE  = 'w+b'
Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
MODE_TRUNCATE_WRITE  = 'wb'
Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
