|
'r+' |
Open for reading and writing; place the file pointer at the beginning of
the file.
|
'w' |
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.
|
'w+' |
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.
|
'a' |
Open for writing only; place the file pointer at the end of the file. If
the file does not exist, attempt to create it.
|
'a+' |
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.
|
'x' |
Create and open for writing only; place the file pointer at the beginning
of the file. If the file already exists, the fopen() call will 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. This option is
supported in PHP 4.3.2 and later, and only works for local files.
