stream_set_write_buffer
Description
The stream_set_write_buffer of Stream for PHP sets write file buffering on the given stream.
Syntax
stream_set_write_buffer(
resource $stream,
int $size
): intParameters
stream
The file pointer.
size
The number of bytes to buffer.
If size is 0 then write operations are unbuffered. This ensures that all writes with fwrite() are completed before other processes are allowed to write to that output stream.
Return
Returns 0 on success, or another value if the request cannot be honored.
Examples
1 · stream size
<?
$filename = $_SERVER['DOCUMENT_ROOT'] . '/assets/txt/1.txt';
$mode = 'w';
$stream = fopen($filename, $mode);
$size = 1024;
$return = stream_set_write_buffer($stream, $size);
echo $return;
$data = 'hello';
fwrite($stream, $data);
fclose($stream);
