Re: [PHP] eval problem
This doesn't seem to work. Here's my demo.
This returns 000, it should return 743

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;
}

[PHP] eval problem
Hello,
Could someone offer some insight on eval(); I am fairly new at this.
I would like to evaluate numerous variables from a form submission with a
loop, but I can;t even get on to work:
I.e.
He are the variables from my form
wins_1=7
losses_1=0
sort_1=1
wins_2=7
losses_2=4
sort_2=2
wins_3=7
losses_3=4
sort_3=3
I am trying to evaluate the values based on a loop. Here's my current
method
$counter=1;
$wins=eval("\$wins_".$counter);
$wins should return 7 in this example. Where am I going wrong?
Any help would be appreciated.
Thanks,
Greg
