Bug description: ob_start chunk_size 0 and 1 are special?
Description:
------------
User-contributed notes and my own limited experience indicates that 0 and
1 are "special" to the chunk_size in ob_start() and make the callback not
behave as documented.
Can this be documented?
Or was it a bug that got fixed?
Reproduce code:
---------------
<?php
//abuses ob_start callback in CLI to 'tee' output
//to both buffer and stderr
function tee($string){
error_log($string);
return false;
}
ob_start('tee', 0); //fails
ob_start('tee', 1); //fails
ob_start('tee', 2); //works!
?>
Expected result:
----------------
0, 1, and 2 should behave the same, or be documented as special.
