$myFile = "testFile.txt"; $fh = fopen($myFile, 'w') or die("can't open file"); fclose($fh); 判断是否删除了. http://www.manongjc.com/article/1351.html $myFile = "testFile.txt"; unlink($myFile);

$filename = 'file.txt'; fopen($filename,'a+'); if(!unlink($filename)) { echo "文件{$filename}删除失败"; // http://www.manongjc.com/article/1351.html } else { echo "文件{$filename}删除成功"; } ?>

function delFileUnderDir( $dirName="../Smarty/templates/templates_c" ) { // http://www.manongjc.com/article/1351.html if ( $handle = opendir( "$dirName" ) ) { while ( false !== ( $item = readdir( $handle ) ) ) { if ( $item != "." && $item != ".." ) { if ( is_dir( "$dirName/$item" ) ) { delFileUnderDir( "$dirName/$item" ); } else { if( unlink( "$dirName/$item" ) )echo "成功删除文件： $dirName/$item
