// discuss at: http://locutus.io/php/pathinfo/
// original by: Nate
// revised by: Kevin van Zonneveld (http://kvz.io)
// improved by: Brett Zamir (http://brett-zamir.me)
// improved by: Dmitry Gorelenkov
// input by: Timo
// note 1: Inspired by actual PHP source: php5-5.2.6/ext/standard/string.c line #1559
// note 1: The way the bitwise arguments are handled allows for greater flexibility
// note 1: & compatability. We might even standardize this
// note 1: code and use a similar approach for
// note 1: other bitwise PHP functions
// note 1: Locutus tries very hard to stay away from a core.js
// note 1: file with global dependencies, because we like
// note 1: that you can just take a couple of functions and be on your way.
// note 1: But by way we implemented this function,
// note 1: if you want you can still declare the PATHINFO_*
// note 1: yourself, and then you can use:
// note 1: pathinfo('/www/index.html', PATHINFO_BASENAME | PATHINFO_EXTENSION);
// note 1: which makes it fully compliant with PHP syntax.
// example 1: pathinfo('/www/htdocs/index.html', 1)
// returns 1: '/www/htdocs'
// example 2: pathinfo('/www/htdocs/index.html', 'PATHINFO_BASENAME')
// returns 2: 'index.html'
// example 3: pathinfo('/www/htdocs/index.html', 'PATHINFO_EXTENSION')
// returns 3: 'html'
// example 4: pathinfo('/www/htdocs/index.html', 'PATHINFO_FILENAME')
// returns 4: 'index'
// example 5: pathinfo('/www/htdocs/index.html', 2 | 4)
// returns 5: {basename: 'index.html', extension: 'html'}
// example 6: pathinfo('/www/htdocs/index.html', 'PATHINFO_ALL')
// returns 6: {dirname: '/www/htdocs', basename: 'index.html', extension: 'html', filename: 'index'}
// example 7: pathinfo('/www/htdocs/index.html')
// returns 7: {dirname: '/www/htdocs', basename: 'index.html', extension: 'html', filename: 'index'}
