hike!

yes, i'm also one of those guys that rather use textfiles that mysql for storing data.
</joke>
no, i just need to know how to handle some texfiles, since i don't need mysql for this stuff, since all data in the files are numbers and url, so no need to secure them.

i need to know how i can go to the last entry of a textfile, read that number, add '1' and write the new number under the old one.

now, the script should read a string from the url ( ie: "id=12" ) and now should open a textfile "partnercount.txt" go to line 12 ( the partner-id number), read the number in dat line, add '1'.

thats it. i know that this are lame questions, but i'm new to php, and this is the newbie section, so pleeeeease help me.

That's pretty easy stuff. Here's how I'd do it.

UNTESTED CODE, may not be sytactically correct, but you get the gist.

$file="test.txt";
$fp=fopen($file,"r");
$body=fread($fp,filesize($file));
fclose($fp);
$lines=split("\n",$body);
$tmp=$lines[count($lines)-1];
$tmp++;
$fp=fopen($file,"a");
fwrite ($fp,$tmp."\n",1000);
fclose($fp);
