stream_set_write_buffer
Sets write file buffering on the given stream
Description
int stream_set_write_buffer(resource $stream, int $size)
Parameters
-
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 Values
Returns 0 on success, or another value if the request cannot be honored.
Examples
Example #1 stream_set_write_buffer example
The following example demonstrates how to use
stream_set_write_buffer to create an unbuffered stream.
<?php
$fp = fopen($file, "w");
if ($fp) {
if (stream_set_write_buffer($fp, 0) !== 0) {
// changing the buffering failed
}
fwrite($fp, $output);
fclose($fp);
}
?>
