$file-> filesizeStr() formatting

[Pete Jones]

Does anyone have a reference to what you can add as formatting parameters? I assume you can return MB, KB, GB without having to divide them manually?

Don't think it takes parameters. Seems to use this function - wireBytesStr() - https://github.com/ryancramerdesign/ProcessWire/blob/7e8c7c6836282b6b64de81263f5aaa8112fd51ae/wire/core/Functions.php#L1290

< 1024b = bytes, >1024 = kb

This should be extended to something like:

function formatBytes($size, $precision = 2)
{
    $base = log($size, 1024);
    $suffixes = array('', 'K', 'M', 'G', 'T');   

    return round(pow(1024, $base - floor($base)), $precision) .' '. $suffixes[floor($base)];
}

echo formatBytes(24962496);
// 23.81M

echo formatBytes(24962496, 0);
// 24M

echo formatBytes(24962496, 4);
// 23.8061M

...or automatically like wireRelativeTimeStr()

Meanwhile, you can use filesize and format its output however you wish...

This is the one I have always liked:

But I would also vote for an option to automatically calculate the number of decimal places / significant figures.
