When deleting a directory in php, if it is an empty directory, we can directly use rmdir to delete it. However, to delete a non-empty directory, we need to first delete the files in the most sub-directory and then delete the empty directory. In fact, it is deleting the directory recursively.

function delDirAndFile( $dirName )
{
if ( $handle = opendir( “$dirName” ) ) {
while ( false !== ( $item = readdir( $handle ) ) ) {
if ( $item != “.” && $item != “..” ) {
if ( is_dir( “$dirName/$item” ) ) {
delDirAndFile( “$dirName/$item” );
} else {
if( unlink( “$dirName/$item” ) )echo “成功删除文件： $dirName/$item
n”;
}
}
}
closedir( $handle );
if( rmdir( $dirName ) )echo “成功删除目录： $dirName
n”;
}
}
