note 68952 added to function.ini-get

Can someone explain the seemingly useless conversion example provided above by the manual? First of all, the code DOES do arithmetic on the raw string (ex 2M), even though the manual suggests that won't work. As you can see, the unit delimiter is never removed from the input string on the example return_bytes() function. On top of that, each case in the switch does the same math - so the swtich is, well, pointless. It seems that PHP's math system handles the unit notation - what's going on here? ---- Server IP: 64.71.164.2 Probable Submitter: 68.17.221.154 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.ini-get.php Edit -- https://master.php.net/note/edit/68952 Del: integrated -- https://master.php.net/note/delete/68952/integrated Del: useless -- https://master.php.net/note/delete/68952/useless Del: bad code -- https://master.php.net/note/delete/68952/bad+code Del: spam -- https://master.php.net/note/delete/68952/spam Del: non-english -- https://master.php.net/note/delete/68952/non-english Del: in docs -- https://master.php.net/note/delete/68952/in+docs Del: other reasons-- https://master.php.net/note/delete/68952 Reject -- https://master.php.net/note/reject/68952 Search -- https://master.php.net/manage/user-notes.php
