help with script

yeah hi

im trying to use this script to write to the second half of any line in a text file

<?php
$i = "";

$file = file("stats.txt");
$init = $file[$_GET["i"]];
$param = explode(",", $init);
$name = $param[0];
$num = $param[1];

if (file_exists('stats.txt')) 
{
$param[1]++;
$fil = fopen('stats.txt', r);
echo $param[1]+1;
fclose($fil);
$fil = fopen('stats.txt', w);
fwrite($fil, implode(",", $param));
fclose($fil);
}
else
{
$param[1]++;
$fil = fopen('stats.txt', w);
fwrite($fil, implode(",", $param));
echo '1';
fclose($fil);
}
echo implode(",",$param);
?>

where each line in the text file is composed of "string,number". basically, $i should determine the line number to write to and $num should work like a basic counter but i can't quite get this right- it replaces all of my text file with a single-digit "1". im new at this and i nothing i try seems to work.

help?

p.s. i realize this would be easier to do with mysql database but i find myself unable to acquire a decent working one at the moment

Is there a reason you're not using a DBMS for this?

well, to be frank, i can't.

this is the last piece of the puzzle that i need for the project im working on though.

store the parameter and values into CSV format,

aaa,bbb,ccc,dddd
123,456,789,3
aaa,bbb,dd,ww

and you can load with fgetcsv()

One line could exploded, and make an if condition to select that line you want to increment.
And rewrite the whole file with fputcsv()

But, this issue is about 3 lines if you make it with database.

UPDATE counters SET counter=counter+1 WHERE string='my_string';

With phpmyadmin you can easily create this table:
counters (string_id(INT PRIMARY),
string(VARCHAR),
counter(INT))

It would be interesting to know why. Many issues that might appear to be obstructions may have already been circumvented.

But I can see a problem in your logic:

$file = file("stats.txt");
//...
if (file_exists('stats.txt'))

So you read the entire file, and then check to see if it exists. If the file does exist, you do this

$param[1]++;
$fil = fopen('stats.txt', r);
echo $param[1]+1;
fclose($fil);
$fil = fopen('stats.txt', w);
fwrite($fil, implode(",", $param));
fclose($fil);

You increment a variable, open a file, echo the variable (plus one), close the file (without having done anything with it), open the file again, overwrite what was in there, then close the file again.

What you'll need to do is read in the whole file into an array (you're doing that, putting the result in $file, but you're not doing anything with it), change the line in the array you want to change, then write the whole array back out again (instead of just some miscellaneous bits and pieces).
