convert bytes to MB with PHP getSize

[Nancy OShea]

I thought I had cracked this nut from a previous discussion.

DirectoryIterator works great on my local testing server.  But on the remote site, results are an unsorted mess. 

I found a script that takes care of that pretty nicely.

<?php

class SortingIterator implements IteratorAggregate

{

private $iterator = null;

public function __construct(Traversable $iterator, $callback)

{

if (!is_callable($callback)) {

throw new InvalidArgumentException('Given callback is not callable!');

}

$array = iterator_to_array($iterator);

usort($array, $callback);

$this->iterator = new ArrayIterator($array);

}

public function getIterator()

{

return $this->iterator;

}

}

?>

<!--results-->

<ul>

<?php

function mysort($a, $b)

{

return $a->getPathname() > $b->getPathname();

}

$it = new SortingIterator(new RecursiveIteratorIterator(new RecursiveDirectoryIterator('PATH/MY_DIRECTORY')), 'mysort');

foreach ($it as $file) {

echo '<li><a href="' . $file . '">' . $file->getFilename() . '</a> - ' . $file->getSize() .' bytes </li>';

}

?>

</ul>

All I need now is a simple way to convert getSize results from bytes to MB.

Any ideas?

Thanks,

Divide by 1048576 ??

Right.  

'. file->getSize() / 1048576 .'

displays a value like this:  7.0703144073486 MB

I need something like this:   7.08 MB  or this:  7 MB.

Not sure how to do that.

use the php round() function

http://www.php.net/manual/en/function.round.php

round (file->getSize() / 1048576, 2)

Perfect!  Thank you, bregent.
