remove characters, add newline & making a twodimensional array

[goldore]

Well, i'm kind of a newby, but this is what i would like to do in php:

1.
i'm writing all instances of a mysql table to a txt file, but when i add "\n" to go on on the next line, in the txt file there is a square printed. When i try to import the txt file into ms access, the square is not recognized by this program to represent a newline.. how can i add a newline to a txt file, that actually IS a newline (or better: hard return) and that will be recognized as one, when reading the file into another program?

2.
a array contains a string of text, multiple words and interpunction. my first question: how can i remove the interpunction ( i know how to strip slashes and trim spaces..)? secondly, after this, i would like to count all double entries. f.e. when the word computer occurs twice in the sentence, i would like to make an array that is twodimensional: word-number of occurences (f.e. 'computer' '2'). How do i do that, for i don't really understand the phpmanual-explanation about this topic. And thirdly: how do i get both facts (word and number) out of the array? (all this has to produce a word-frequecylist, so if anybody has a clue how to do that......)

3.
how can i upload an image to my server and then call the image back into a webpage, just by using php?

1. instead putting \n , try putting '\r\n' (without quotes).

Part one:
And that is to use <br>.

<?
//php code part one or whatever
?>
<br>
<?
//secondpart
?>

That is a rlly rubbish way of doing it but I belive it works.

Part 2:
😐 I have no idea at all!

Part 3 (my own scripts
This is the form to upload:

<form name="form1" method="post" action="process.php" enctype="multipart/form-data">
<p>
<input type="file" name="imagefile" size="20">
<br>
<input type="submit" name="Submit" value="Submit"> </p>
</form>

This is the process code:

<?
$image_name = $_FILES['imagefile']['name'];
$image_size = $_FILES['imagefile']['size'];
$image_type = $_FILES['imagefile']['type'];
?>
<?
session_start();
ob_start();
if(isset($Submit)) 
{
copy ($_FILES['imagefile']['tmp_name'], $_FILES['imagefile']['name']) or die ("Could not copy"); 
}

header("Location: http://yoururl.com/dir_this_file_is_in/$image_name");
?>

There may be some slips in that code somewhere.. but it works for me!
