write an array to a file

[Anon]

Hi,
I'm building a counter for more than one page.
The counter *.txt looks like:
1
1
1
1

the "1" are the hit numbers.
At the beginning I copy the file in an array:

$fpt = count.txt;
$line = file($fpt);
Le'ts say I want to modify the counter in the 3rd raw:
$count = $lind[2];
$count++;
Now $line looks like:
1
1
2
1
I want to save the array $line back to the file in a way to have my files looking like:
1
1
2
1

Help
Thank you
Maria

fopen() the file fwrite() your data and fclose() the file.. Or am I missing something?

You replace the values in your array without changing the order (which is hard not to do ,really) and you'll be fine..

This is counter.txt:

And this is the program I wrote that I access with somthing like:
<IMG SRC="fileincrement.php3?nome=main" height="0" width="0">

<?

// - chmod this document to 755! -
$fpt = "counter.txt"; // path to log file - chmod it to 666

echo $nome;
if (!file_exists($fpt)) {
$count_dat = fopen($fpt,'w+');//aprerto in scrittura e se non esiste lo crea
$count = 1;
fwrite($count_dat,$count);
fclose($count_dat);
}
//take $nome from the page that called the *.php3 and decide which counter to incrememnt
else {
switch ($nome) {
case main:
$position=0;
break;
case msc:
$position=1;
break;
case kd:
$position=2;
break;
case american:
$position=3;
break;
case cruisewest:
$position=4;
break;
case norwegian:
$position=5;
break;
case delimann:
$position=6;
break;
case riverbarge:
$position=7;
break;
case royal:
$position=8;
break;
case star:
$position=9;
break;
case temptress:
$position=10;
break;
case windjammer:
$position=11;
break;
case world:
$position=12;
break;
}

$line = file($fpt); //Reads entire file into an array
echo "prima incremento";
echo $line[$position];
$line[$position]=$line[$position]+1;; //incrementa il contatore della pagina vista

echo "dopo incremento";
echo $line[$position];

$tempfile = fopen("tempfile.txt",'w+'); //nuovo file

fwrite($tempfile, $line); //write the array in tempfile

fclose($tempfile); //chiude il tempfile

copy("tempfile.txt","counter.txt"); //sovrascrive il counter con il tempfile

//delate tempfile

$EraseAll = fopen("tempfile.txt",'w');
fwrite($EraseAll,"");
fclose($EraseAll);

}

?>

Could you be so kind to tell me why "fwrite($tempfile, $line); " this is not working and my counter.txt becomes like this: Array?
Thank you

This :
switch ($nome) {
case main:
$position=0;
break;

Should be this :

switch ($nome) {
case "main":
$position=0;
break;

if you're commparing the variable to the string "main" that is.
