PHP set_file_buffer() Function


Hello dear readers! welcome back to another edition of our tutorial on PHP. In this tutorial guide, we are going to be discussing about the PHP set_file_buffer() Function.

The built-in PHP set_file_buffer() function sets the buffer size of an open file. The output using the built-in PHP fwrite() function is normally buffered at 8k. So, if two processes write to the same file, each can write up to 8k before pausing and allowing others to write. If the buffer is 0, the write operations are unbuffered, which means that the first write process can be completed before allowing other processes to write.

Syntax

Following below is the syntax to use this function -

set_file_buffer(file, buffer)


This function is an alias of the built-in stream_set_write_buffer() function.

Return Value

This built-in function returns 0 on success, else it returns EOF.

Example

Try out the below example -

<?php
   $file = fopen("/PhpProject/sample.txt", "w");
   if ($file) {
      set_file_buffer($file, 0);
      fwrite($file, "Hello World!");
      
      fclose($file);
   }
?>
