Getting data from a txt file.

[Anon]

I'm new at PHP and I was wanting to create a text file to count uploads to my site. Going with a txt file, because my host doesn't support sql databases. I got some help from someone else on here, with some code on how to read the data from a text
file, separated by commas'.

$filename = "blah.txt";
$file = file($filename);
for($count=0;$count<count($file);$count++)
{
$line = explode(",",$file[$count]);
//$line will be an array containing
//each value that was seperated by a comma
echo $line[0];
echo $line[1];
echo "<br>";
}

But I'm wanting to do a an if statement and list the 5 top uploaders, but it will need to be able to search through the document. I am able to do an if statment, but it only does the last line in my blah.txt since its not keeping track of the variables. Is this possible with a txt file, or should I just find another host that supports sql?

Use an associative array to store the key you want to match on and increment it each time through the for loop. Something like this should work but will

$filename = "blah.txt";
$file = file($filename);

for($count=0;$count<count($file);$count++)
{
$line = explode(",",$file[$count]);

(isset($cntr[$line[0]])) ? $cntr[$line[0]]++ : $cntr[$line[0]]=1;
}
arsort ($cntr);
reset ($cntr);
while (list ($key, $val) = each ($cntr)) {
echo "$key = $val <BR>";
}
//
// blah.txt contains 3 lines:
//
// john,junk
// mary,junk
// john,stuff
//
// output should be:

john = 2
mary = 1
