This example describes how to automatically clean up images in PHP. Share it with you for your reference. The specific implementation method is as follows:

<? Php/*** image cleanup scheduler, delete files not accessed in the next two weeks */$ sRootPath = dirname (_ FILE _); // define (TIME_LINE, "-7 day"); // The time when the image is not accessed for several days after deletion $ dir = $ sRootPath. DIRECTORY_SEPARATOR. 'upload'; $ iTimeLine = strtotime ("-7 day"); // $ iTimeLine = time (); $ sHandDate = date ("Ymd "); $ sLogDir = dirname (_ FILE __). DIRECTORY_SEPARATOR. 'imglog'; $ sLog = $slogdir.directory_separator.mongoshanddate.'.txt '; if (! File_exists ($ sLogDir) mkdir ($ sLogDir, 0777, true); _ clearFile ($ dir, $ iTimeLine, $ sLog); $ sEnd = 'at '. "\ t ". date ("Y-m-d H: I: s "). "\ t ". 'exec over '. "\ n"; echo $ sEnd; error_log ($ sEnd, 3, $ sLog);/*** clear the file operation, input the path * @ param unknown_type $ sPath */function _ clearFile ($ sPath, $ iTimeLine, $ sLog) {if (is_dir ($ sPath )) {$ fp = opendir ($ sPath); while (! False = ($ fn = readdir ($ fp) {if ($ fn = '. '| $ fn = '.. ') continue; $ sFilePath = $ sPath. DIRECTORY_SEPARATOR. $ fn; _ clearFile ($ sFilePath, $ iTimeLine, $ sLog) ;}} else {if ($ sPath! = '.' & $ SPath! = '.. '){//... The file is skipped directly and $ iLastView = fileatime ($ sPath) is not processed; if ($ iLastView <$ iTimeLine) {if (@ unlink ($ sPath) === true) {// echo date ("Y-m-d H: I: s "). 'File deleted successfully '. $ sPath; // file_put_contents ($ sLog, 'success del file :'. $ sPath. "\ n", FILE_APPEND); // exit; $ str = date ("Y-m-d H: I: s "). "\ t ". 'Success del file :'. '['. $ sPath. ']'. "\ n"; error_log ($ str, 3, $ sLog); // exit ;}}}}?>
