[SOLVED] PHP file_exists complex! by prashker on 03-27-2010 at 04:34 PM

Folder Structure

/home/admin/Downloads/Downloading/Back.To.The.Future
/home/admin/Downloads/Forward.To.The.Past

php code:
//Directories to search
$monitor = array(
'/home/admin/Downloads/Downloading/',
'/home/admin/Downloads/',
'/home/admin/ThirdFolder/'
);

//Looking for $release
$release = array('Back.To.The.Future','Forward.To.The.Past','NonExistingFolder');

foreach ($monitor as $path) {
foreach ($release as $name) {

if (file_exists($path . $name)) {
echo $name . ' exists in ' $path;
}
}
}

In my mind, I am expecting an output of

Back.To.The.Future exists in /home/admin/Downloads/Downloading/
and
Forward.To.The.Past exists in /home/admin/Downloads/

What I want to add to this code is the following
If $name does not exist in ANY of the $monitor folders, $delete[] = $name;

In which case, $delete[0] would be NonExistingFolder

php code:
//Directories to search
$monitor = array(
'/home/admin/Downloads/Downloading/',
'/home/admin/Downloads/',
'/home/admin/ThirdFolder/'
);

//Looking for $release
$release = array('Back.To.The.Future','Forward.To.The.Past','NonExistingFolder');

>>>$delete = array_flip($release); <<<

foreach ($monitor as $path) {
foreach ($release as $name) {

if (file_exists($path . $name)) {
echo $name . ' exists in ' $path;
>>> unset($delete[$name]); <<<
}
}
}

>>>$delete = array_keys($delete); <<<

Dunno if it works, please try

php code:
Array
(
[0] => Array
(
[releaseid] => 1
[name] => Back.To.The.Future
[filesize] => 1173363271
[files] => 26
[creation] => 1269378095
)

[1] => Array
(
[releaseid] => 2
[name] => Future.To.The.Past
[filesize] => 24000
[files] => 25
[creation] => 1269491369
)
}

That's what the actual format is for a $release[], so I'm not sure how array_flip will work, I assume extra work will be needed ( (l)

)

The code works, all that needs to be done is a proper flip

I'll take that as "Please do it for me"

Maybe the following lines replacing the array_flip line would work.

php code:
foreach ($release as $release_item) {
$delete[$release_item['name']] = "";
}
