How can I delete blank line?

[miikha27]

My code add contents of form into text file. But it also add empty line into end. How can I delete that last empty line? My script look like this:

.
.
.
$new_array[] = "$contents\r\n";

} else {

$new_array[] = $line;

}
}
$data = implode('', $new_array);


$fp = fopen( $filename , "a" );
flock( $fp, LOCK_EX );


$data=trim($data, "\r\n.");
fwrite( $fp, $data );


flock( $fp, LOCK_UN );
fclose( $fp );



?>

I try to use trim but then script writes contents of file into same line.

If all the entries being added are single lines and not terminated with \r\n then don't add \r\n as you're going along, then at the end implode the data together with "\r\n" instead, and there should be no need for the trim.
