The documentation states that max_upload_filesize is an
integer, although the result from ini_get is "2M". This is
problematic for the following reasons:
 
1. With the documentation stating the format as an
integer, code can be written to output BAD code such as:
 
$my_value = 2M;
 
I fell into this trap and didn't locate the problem easily
because my test installations (unfortunately) stated the
max_upload_filesize as a true integer inside php.ini.
 
2. It is not clear how PHP handles the output of GOOD code
like:
 
$my_value = "2M";
 
If I later have code like:
 
if ($my_value > $this_value)
// i.e., if ("2M" > "345")
 
Will it break? Will "2M" be considered an integer and
converted automatically to 2097152? If this is the case
then it is not immediately evident inside of the
documentation.
