PHP删除除以下内容之外的所有文件

Question

I've got this script working to delete all files but leave just the selected ones, How can i change it so on the .exe file it catches any filename?

$leave_files = array(''.$filename.'.exe', ''.$filename.'.nfo', ''.$filename.'.sfv');
foreach( glob("$foldername/*") as $file ) {
    if( !in_array(basename($file), $leave_files) ) {
            unlink($file);
        }

for the .exe file i want it to capture ANY filename

Thanks

Answer 1

$leave_files = array('' . $filename . '.exe', '' . $filename . '.nfo', '' . $filename . '.sfv');

foreach (glob("$foldername/*") as $file) {
    if (!in_array(basename($file), $leave_files)) {
        if (substr($file, -4) == ".exe") {
            continue;
        } else {
            unlink($file);
        }
    }
}

You can check if the last 4 signs of the filename are ".exe" and then don't delete them. (or delete them, depends on what you mean)

if(substr($filename,-4) == ".exe")

Check the extension:

if(!in_array(basename($file), $leave_files) && pathinfo($file, PATHINFO_EXTENSION) != 'exe') {

Or exclude them in the glob() :

foreach(array_diff(glob("$foldername/*"), glob("$foldername/*.exe") as $file) {
