$phar->isWritable() works now too View as Markdown

Hi,

I re-read the messages, and realized I had misunderstood what was being
requested, although it did pay off in finding a subtle bug in
is_writeable() for files within a phar.

I just implemented Phar->isWritable(), which can be used to detect the
right combination of file permissions, archive type, and phar.readonly
for creating archives. Thus, this can be used:

<?php
$phar = new Phar('blah.phar');
if ($phar->isWritable()) {
// add files or other modifications
}
?>

This should satisfy Elizabeth's wishlist, so to satisfy Lars and
Benjamin, we need to clean up the conversion/compression API.
