Orada yaklaşık PHP SSS bir giriştir shorthand notation:

A few PHP directives may also take on shorthand byte values, as opposed to only integer byte values. What are all the available shorthand byte options? And can I use these outside of php.ini?

The available options are K (for Kilobytes), M (for Megabytes) and G (for Gigabytes; available since PHP 5.1.0), these are case insensitive. Anything else assumes bytes. 1M equals one Megabyte or 1048576 bytes. 1K equals one Kilobyte or 1024 bytes. You may not use these shorthand notations outside of php.ini, instead use an integer value of bytes. See the ini_get() documentation for an example on how to convert these values.

Yani, senin durumunda, 8M 8 000 000 byte anlamına gelmez, ancak 8 388 608 bayt anlamına gelmez.
