How to delete images from a folder using PHP Script

Question

We need to delete images created in linux file system. in a path /home/user/img/ (All images)

We have tried using unlink() but it is taking lot of time to delete it. Can someone help us how to delete images using linux commands must be passed with php script. I think rm command can do quickly but i am confused how to use

Our script:

$locationIMG_p="/home/user/img/";
$location_p="/home/user/img/";

$opend=opendir($locationIMG_p);

while(false!==($rf=readdir($opend)))
{           
    unlink($locationIMG_p.$rf);
}         

closedir($opend);

I can't see a command that is faster than unlink for what you want. You could potentially move the image to a temp folder and have a cronjob clear out that folder every hour or something, but I doubt that is faster =/ — Relequestual

Maybe try using shell command for this?

$cmd = "rm -f {$locationIMG_p}*"; exec($cmd);

But You must be very careful when using this ;)

//edit You should add some validation at path and use escapeshellarg

//edit2

Also You can try using DirectoryIterator as follows:

$di = new DirectoryIterator(path);
foreach($di as $file)
{
   if( $file->isFile() )
   {
        unlink($file->getPathname());
   }
}

foreach(glob('/www/images/*.*') as $file)
    if(is_file($file))
        @unlink($file);

glob() returns a list of file matching a wildcard pattern.

unlink() deletes the given file name (and returns if it was successful or not).

The @ before PHP function names forces PHP to suppress function errors.

The wildcard depends on what you want to delete. *.* is for all files, while *.jpg is for jpg files. Note that glob also returns directories, so If you have a directory named images.jpg, it will return it as well, thus causing unlink to fail since it deletes files only.

is_file() ensures you only attempt to delete files.
