计算目录php中的文件数量

Question

I'm working on a slightly new project. I wanted to know how to make it so it counts how many files are in a certain directory.

<div id="header">
<?php 
    $dir = opendir('uploads/'); # This is the directory it will count from
    $i = 0; # Integer starts at 0 before counting

    # While false is not equal to the filedirectory
    while (false !== ($file = readdir($dir))) { 
        if (!in_array($file, array('.', '..') and !is_dir($file)) $i++;
    }

    echo "There were $i files"; # Prints out how many were in the directory
?>
</div>

This is what I have so far (from searching). However it is not appearing properly? I have added a few notes so feel free to remove them, they are just so I can understand it as best as I can.

If you require some more information or feel as if I haven't described this enough please feel free to state so.

You can simply do the following :

$fi = new FilesystemIterator(__DIR__, FilesystemIterator::SKIP_DOTS);
printf("There were %d Files", iterator_count($fi));
