<?php

// Short Ternary Operators

$var = 'SomeValue';

$output = $var ? $var : 'default';

$output = $var ?: 'default'; // PHP >= 5.3

// Directory Listing #3

$dir = 'application/modules/';

foreach(new DirectoryIterator($dir) as $fileInfo) {
  echo "Filename is: " . $fileInfo->getFilename();
}

// Exploded String values

$string = 'bazinga.foo.bar.suitup';

$values = explode('.', $string);
$sheldon = $values[0]; //bazinga
$barney = $values[3]; //suitup

list($sheldon, , , $barney) = explode('.', $string);

// PHP 5.4 stuff

$sheldon = explode('.', $string)[0];
$barney = explode('.', $string)[3];


// File Path Information

$path = '/some/directory/in/filesystem/file.some.txt';

$fileInfo = pathinfo($path);

$fileInfo['dirname'] === pathinfo($path, PATHINFO_DIRNAME);
$fileInfo['basename'] === pathinfo($path, PATHINFO_BASENAME);
$fileInfo['extension'] === pathinfo($path, PATHINFO_EXTENSION);
$fileInfo['filename'] === pathinfo($path, PATHINFO_FILENAME);
