Programming PHP

If include is specified and is true, fopen( ) tries to locate the file in the current include path.
If any error occurs while attempting to open the file, false is returned.
fpassthru
int fpassthru(int handle)
Outputs the file pointed to by handle and closes the file. The file is output from the current
file pointer location to EOF. If any error occurs, false is returned; if the operation is
successful, true is returned.
fputs
bool fputs(int handle, string string[, int length])
This function is an alias for fwrite( ).
fread
string fread(int handle, int length)
Reads length bytes from the file referenced by handle and returns them as a string. If fewer
than length bytes are available before EOF is reached, the bytes up to EOF are returned.
fscanf
w Open the file for writing. If the file exists, it will be truncated to zero
length; if the file doesn’t already exist, it will be created.
w+ Open the file for reading and writing. If the file exists, it will be truncated
to zero length; if the file doesn’t already exist, it will be created.
The file pointer starts at the beginning of the file.
a Open the file for writing. If the file exists, the file pointer will be at the
end of the file; if the file does not exist, it is created.
a+ Open the file for reading and writing. If the file exists, the file pointer
will be at the end of the file; if the file does not exist, it is created.
mixed fscanf(int handle, string format[, string name1[, ... string nameN]])
Reads data from the file referenced by handle and returns a value from it based on format.
For more information on how to use this function, see sscanf.
If the optional name1 through nameN parameters are not given, the values scanned from the
file are returned as an array; otherwise, they are put into the variables named by name1
through nameN.
