Description:
------------
When using any sort of directory listings the Phar::mount()'ed files don't show up. Ex: readdir() scandir() SPL::DirectoryIterator() For the test below, the following folder structure should be setup:

make.php = The test script below
list.php = Also in the test script below
page1.html = <p>Page 1</p>
page2.html = <p>Page 2</p>
page3.html = <p>Page 3</p>

Test script:
---------------
<?php
// make.php

try {
    $p = new Phar('test.phar');
    $p->addFile('list.php');
    $p->addFile('page1.html');
    $p->addFile('page3.html');
    $p->setStub('<?php
Phar::interceptFileFuncs();
Phar::webPhar("test.phar", "list.php");
Phar::mount(__DIR__ . "/page2.html", "page2.html");
__HALT_COMPILER();');
    echo 'Done making test.phar';
} catch (Exception $e) {
    echo 'Exception caught: ' . $e->getMessage();
}
?>



<?php 
// list.php

echo "<h3>readdir()</h3>\r\n";
$handle = opendir(Phar::running());
while (false !== ($file = readdir($handle))) {
    if ($file == "." || $file == "..") continue;
    echo "$file<br>\r\n";
}

echo "<h3>scandir()</h3>\r\n";
foreach (scandir(Phar::running()) as $file) {
    if ($file == "." || $file == "..") continue;
    echo "$file<br>\r\n";
}

echo "<h3>SPL::DirectoryIterator()</h3>\r\n";
foreach (new DirectoryIterator(Phar::running()) as $file) {
    if ($file->isDot()) continue;
    echo $file->getFilename() . "<br>\r\n";
}
?>
