Re: how to delete some lines in a file

A little more general: $lines=file("testfile"); // all array elements will have trailing newline // array manipulation here; new array elements must have trailing newline $fp=fopen("testfile","w"); reset($lines); while(list($key,$val)=each($lines)) fwrite($fp,$val); fclose($fp); Regards, Carroll Barrett -----Original Message----- From: Hans H.
