php - script to fix folder structure

I am changing the way I save files on the back-end of my website from:

uploads/item/x/subitem/y/document.pdf

Where x and y are integer id's, changing it to:

uploads/item/x/subitem/y/report/document.pdf

I need to change the current folder directory as well, which is over 1000 records. Is there a nice way to fix this structure in php without addressing each folder in nested loops, I just need to add another folder before the document.

EDIT:

This was the command I was trying to find!

foreach(glob('uploads/item开发者_开发问答/*/subitem/*/*') as $filePath)

Thanks for the help guys.

Have you tried php's rename:

rename("uploads/item/x/subitem/y","uploads/item/x/subitem/y/report");

// Change the current directory to the folder containing all your data
chdir('uploads/item/x/subitem/y');

// Attempt to create the report directory if it does not already exist
if ((file_exists('report') && is_dir('report')) || mkdir('report'))
{
    // Move every PDF file in the current directory
    foreach (glob('*.pdf') as $File)
    {
        rename($File, 'report/' . $File);
    }
}
else
{
    echo 'ERROR! Directory could not be created.';
}

Couldn't you just create a folder report/ under y/ and then move all files in y/ into report/? This doesn't require PHP at all.

EDIT: My bash is very rusty so there are probably a lot of syntax errors in here. But this is the basic idea:

for x in /fullpath/uploads/item/*
do
    for y in uploads/item/$x/subitem/*
    do
        cd /fullpath/uploads/item/$x/subitem/$y
        mkdir report/
        mv * report/
    done
done
