delete folder/contents based on date
Posted on 2013-05-21
I have a test environment where I create a group of sub folders within a parent folder.
Each of the sub-folders has a number of documents in each.
ie.
Parent Folder
Subfolder A
file1
file2
Subfolder B
file1
I want to create a cron task that will run a script which will remove any subdirectory that is 2 days old.
My challenge is to cycle thru all contents of parentfolder, examine the date of each folder and if the date is older than 2 day delete the contents that folder and then the folder itself.
I don't know the names of the folders in advance
If I use code such as
readdir($parentFolder)
who do I tell if the item is a folder or a file
This script doesn't need to be recursive, as there are not folders within subFolders

You can use a simple php page to do that.
Use the stat() to get date info
Exemple_:
Modifiy the script to compare the mtime with current time minus 2 days...

$stat = stat('\path\to\directory');

Hi,
thanks for your follow up and help
I'm not familiar with the RecursiveIteratorIterator class
With slight modification for variable names I get the following error
Fatal error: Undefined class constant 'SKIP_DOTS'
Do I need to declare anything before using the class ?

You can try to use only the
new RecursiveIteratorIterator(
new RecursiveIteratorIterator(
thanks for the advice
that works to a large degree
however, it does two things that I hadn't wanted
1. it deletes files in the parentFolder.... I only want to delete subFolders
2. it deletes the parentFolder as well
So, if I call the function
delete_recursive($parentFo
everthing, including the parentFolder is deleted
thanks

I'm sorry, but how do it apply an if statement to check for the base path
I'm not familiar with this class

Try to ignore the self remove path
function delete_recursive($path)
{
if (is_dir($path))
{
$iterator = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($path, RecursiveDirectoryIterator::SKIP_DOTS),
RecursiveIteratorIterator::CHILD_FIRST
);
foreach ($iterator as $file)
{
if ($file->isDir())
{
rmdir($file->getPathname());
}
else
{
unlink($file->getPathname());
}
}
}
}
