stream_set_write_bufferSets write file buffering on the given stream

Description

int stream_set_write_buffer ( resource $stream , int $buffer )

Sets the buffering for write operations on the given stream to buffer bytes.

Parameters

stream

The file pointer.

buffer

The number of bytes to buffer. If buffer 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

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 (
$fp) {
  if (
stream_set_write_buffer($fp0) !== 0) {
      
// changing the buffering failed
  
}
  
fwrite($fp$output);
  
fclose($fp);
}
?>
