Convert SplFileInfo Object To Array Problems-CodePudding

I have searched SO and went through all of them. Many don't seem to apply to my problem but supplied information that I tried to apply. Result was many parse errors. I can't seem to apply them correctly. This is my first use of iterators. So, after a few days trying I need help.

The original code was taken form the PHP manual. I turned it into a function and added the code to remove dot and dot dot entries (. and ..). I then added code to return an array of files so I can use it in a foreach statement. Problem is that I don't have access to the properties.

<?php
function getDirectoryListing($path)
{
 $dir_iterator = new RecursiveDirectoryIterator($path);
 $iterator = new RecursiveIteratorIterator($dir_iterator, RecursiveIteratorIterator::SELF_FIRST);
 $files = array();
 foreach($iterator as $file)
 {
  if(strpos($file, ".", -1) !== false)
  {
   continue;
  } // Closing brace for if(strpos($file, ".", -1) !== false)
  $files[] = $file;
 } // Closing brace for foreach($iterator as $file)
 return $files;
}

$files = getDirectoryListing("I:\cef-inc.net/images/database/");
print_r($files);
?>

When I print_r $files I get:

Array ( [0] => SplFileInfo Object ( [pathName:SplFileInfo:private] => I:\cef-inc.net/images/database\calendar.ico [fileName:SplFileInfo:private] => calendar.ico ) )

When I echo $file in the foreach I get the pathName but not the fileName.

What do I need to do in the function to put everything in an array?

Thank you for looking,

You get an array of SplFileInfo objects. You should use their getFilename() method to access their filename without the path. When you echo the object, you’re calling __tostring() method.
