set_file_buffer — Sets the file buffer size.
bool set_file_buffer(file_handle, buffer);
resource file_handle: File
int buffer: Buffer size in
TRUE on success; FALSE on error
With this function, you can change the file buffer size
for the specified file handle. Specifying a buffer size
of 0 changes the operation mode to "unbuffered";
all other values change the operation mode to "fully
buffered," using the given number of bytes.
Example 348. Change file
buffer to 4KB
$fh = fopen("text.txt", "r+");
$buffer_size = 4096;
echo ("Couldn't change file buffer size");
echo ("New file buffer size is $buffer_size bytes");
