请记住从PHP文件创建的教训,我们创建了一个文件,名为testFile.txt 。
$myFile = "testFile.txt";$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);
例
$filename = 'file.txt';fopen($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";}?>
删除目录下所有文件
function delFileUnderDir( $dirName="../Smarty/templates/templates_c" ){// http://www.manongjc.com/article/1351.htmlif ( $handle = opendir( "$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: $dirName/$itemn"; } } } closedir( $handle );}}
