Handling files

Those files are giving me a headache. I have a simple form 2 fields and I want to write the content of those 2 fields to a file. Then on another page I want to display the content of the file.

Name:
Description:

$filename="files/new.txt";

if  (isset ($_POST['name'])  || isset ($_POST['desc']))
{

 $name=trim($_POST['name']);
$desc=trim($_POST['desc']);

// get rid of enter 
    $name = str_replace("\n","",$name);
    $desc = str_replace("\n","",$desc);


$data = trim($name."\n".$desc."\n"); 

//opening a file
    $fp = fopen($filename, "w+") ;

//writing to a file
    fwrite($fp, $data);

//closing a file
    fclose($fp);
}

in another file I want to read those 2 fields in 2 seperate lines

$lines=file('files/new.txt');
 for ($i=1;$i<count($lines);$i++)    

  {
   echo $lines[$i] . "<br /><br />\n";
   }

In the file new.txt everything is in 1 line. Why is it in 1 line if I use $data = trim($name."\n".$desc."\n");

Windows uses \t\n

You're starting your "for" count at 1, so you're not seeing all the data in the file. Arrays are indexed starting with 0. A surer way to do it:

$lines = file('files/new.txt');
foreach ($lines as $line) {
    echo $line . "<br /><br />\n";
}

Also, "trim" in this statement:

$data = trim($name."\n".$desc."\n");

removes the "\n" you try to add. So if you have more than one name/desc pair, the lines will not come out right.

Oops, forgot [man]trim/man will strip newlines aswell.

I don't want the 0 line to be displayed because its input=
This input= is needed for the file to be displayed in flash. Unless there is a way to change that but I tried and without input= it doesnt work.

Is there a way to display the line but starting from 7th character, so that input= is not displayed?
