eval() is overkill and can be dangerous.
I'd use variable variables instead:
$wins = 0;
for ($counter=1; $counter=3; $counter++) {
$var = $wins_$counter;
$wins = $wins + $$var;
}

Re: [PHP] eval problem
This doesn't seem to work. Here's my demo.
?
$wins_1=7;
$losses_1=0;
$sort_1=1;
$wins_2=4;
$losses_2=4;
$sort_2=2;
$wins_3=3;
$losses_3=4;
$sort_3=3;
$wins = 0;
for ($counter=1; $counter=3; $counter++) {
$var = $wins_$counter;
$wins = $wins + $$var;
echo($wins);
}
?
This returns 000, it should return 743

Re: [PHP] eval problem
hmm... I must be doing something wrong. This is still returning 000

$wins_1=7;

$sort_1=1;
$wins_2=4;
$losses_2=4;
$sort_2=2;
$wins_3=3;
