Datetime format + Unit conversion

Recommended Posts

Hey Guys,

Im fairly newbie with php + mysql still and have written up a script yesterday but am having a few issues as I'm having problems getting my head around variables.

I am outputting stats from a program into a mysql database and am outputting these stats with php however there are 2 parts I would like to reformat. The sharesize stored in the database is in bytes which I would like to reformat to kB/mb/gb/tb as appropriate. The other thing is the last logged in date I would like to take from the unix display YYYY-MM-DD Hh:Mm:Ss, to something such as 25th April, 2006 11.58pm for example. Ive attached below my code so far, with $sharesize & $last_used being the variables concerned, if anyone would be able to advise on how to do this :) Also the page can be viewed at [a href=\"http://ravestyle.no-ip.com/ynhub/\" target=\"_blank\"]http://ravestyle.no-ip.com/ynhub/[/a] would really appreciate some help on this. Thanks guys

hmm .. i'm not sure on the date formmating but as for the bytes calculation, i would do somthing like this

[code]
$bytes = *query your database here*

$kb = $bytes / 1024; //1024 being the amount of bites in a kilobyte
$mb = $kb / 1024;
$gb = $mb / 1024;
$tb = $gb / 1024;
[/code]
and then reference them through out your code as needed.

**additional thought, if you wanted to use an if / else statement you could tell the code to look at the $bytes var and display the correct size id based on the amount of bytes.

something like
[code]
if ($bytes > 1000000000){
echo 'Total Space = ' . $gb . 'gb.';
}
[/code]


PS: I'm a bit a noob myself, so these may not the be perfect way, but they are the ways I have found to work.

hope this helps.

Chris

Cheers for the help, the date code is exactly what I wanted :D
The unit conversion works but is not quite what I wanted as I would like it to convert to MB/GB/TB and work out which to display it as, as the figures range between few hundred mb's up to few tb's. I will keep working on that part though :)

like i said, you would use if / else statments to determine what gets displayed.

something like
[code]
if ($bytes > 1000000000){
echo 'Total Space = ' . $gb . 'gb.';
}
[/code]
you will just need to incorportate them all into one function.

Try

[code]function getSize ($sz) {
         $units = array ('bytes', 'Kb', 'Mb', 'Gb', 'Tb');
         $i = 0;
         while ($sz > 1000) {
             $i++;
             $sz /= 1024;
         }
         return sprintf('%8.0f %s', $sz, $units[$i]);
}

$sizes = array (1, 12, 123, 1234, 12345, 123456, 1234567, 12345678, 123456789,
         1234567899, 12345678999, 123456789999, 1234567899999, 12345678999999);

echo '<pre>';
foreach ($sizes as $sz) {
         printf('%20s %s<br/>', $sz, getSize($sz));
}
echo '</pre>';[/code]
