function langueread( ) { /*读*/ $file_name = "langue.dat"; $file_resourcs = fopen($file_name,"r"); $file_read = fread( $file_resourcs, filesize($file_name) ); /*读*/ fclose($file_resourcs);  return $file_read;}function languewrite( ) { /*读*/ $file_name = "langue.dat"; $file_resourcs = fopen($file_name,"r"); $file_read = fread( $file_resourcs, filesize($file_name) ); /*读*/ /*写*/ $file_resourcs = fopen($file_name,"w"); $num = $file_read+1; fwrite($file_resourcs,"$num"); /*写*/  fclose($file_resourcs);}
