在PHP中每24小时删除一个文件夹的所有文件

Question

I searched some related questions but unable to understand them.

I want to delete all the files of folder after every 24 hours but sometimes I get warnings and sometime it works. The folder path is c:\wamp\www\Jamil.

Here's the source:

<?php
$dir = "Jamil"; // directory name

foreach (scandir($dir) as $item) {
    if ($item == '.' || $item == '..')
        continue;

        if((time() - filemtime($item)) >= 30    && is_file($item)){
        unlink($dir.DIRECTORY_SEPARATOR.$item);
        echo "All files deleted";}
    }   
//rmdir($dir);

?>

I copied the code from various sites. Can anyone help? I get this warning:

Warning: filemtime() [function.filemtime]: stat failed for jamil.html in C:\wamp\www\delete1.php on line 10

Try this function;

function wipedir($dir) {
        try{  
            if(is_dir($dir)){
                $mydir = opendir($dir);
                while(false !== ($file = readdir($mydir))) {
                    if($file != "." && $file != "..") {
                        chmod($dir.$file, 0777);
                        if(is_dir($dir.$file)) {
                            chdir('.');
                            destroy($dir.$file.'/');
                            rmdir($dir.$file) or DIE("Unable to delete $dir$file");
                        }else{
                            unlink($dir.$file) or DIE("Unable to delete $dir$file");
                        }
                    }
                }
                closedir($mydir);

                return true;
            }else{return true;}
        }catch (Exception $e){return false;} 
    }

So usage would be

$dir = 'Jamil';
wipedir($dir);

This should be placed in a file run by crontab etc at the specified interval.
