write txt not good need to clean empty line

superbau

hi,
I've one problem for remove one line into one txt (mail.txt)
When i remove the select line, in my email.txt left one empty space.

uhm.. i post the code:

<?php
if ($emileliminare == null){
echo "devi inserire un indirizzo email!!!";
}else{
//APRE IL FILE E LEGGE I CONTENUTI IN UNA VARIABILE
$filename="email.txt";
$fp = fopen ($filename, "r+") or die ("impossibile aprire il database");
$contents = fread ($fp, filesize ($filename));

//ELIMINA SPAZI INIZIO E FINE del messaggio da inviare.
$emileliminare = trim($emileliminare);

//SOSTITUISCE TUTTI LE EMAIL
$new_contents = str_replace ("$emileliminare", null, $contents);

//ELIMINA SPAZI INIZIO E FINE DEL FILE
$fok= trim($new_contents);


//SCRIVE IL NUOVO CONTENUTO NEL FILE
rewind ($fp);
fwrite($fp, $fok);
//ASSICURA CHE NON VENGONO AGGIUNTI CARATTERI EXTRA SE IL NOME INSERITO E' + PICCOLO DELL'ORIGINALE
ftruncate($fp, ftell($fp));
fclose ($fp);
}
?>

The mail.txt is write after remove line:

email1
email2

email4

email5

this is the result.

I want have this result in my email.txt :
email1
email2
email4
email5
like this, without empty space.

tnk for all help

I think you need to remove the newline character too

$new_contents = str_replace ("$emileliminare\n", "", $contents);

I had this problem too, It seemed top be doing rather odd things with inserting line breaks where i didn't want them. I got round it by imploding all the lines onto one, and then as soon as I opened the file for analysis I would explode the first line only. Like this:

//when opening the file
$file = file('stuff.txt');
$file = explode("||", $file[0]);

//when writing the file
$writeline = implode("||", $file);

That worked fine for me. I expect there is a more 'correct' way to get round the problem, but that was my way.
