variable number of vars

[zmola]

hi all. i've been looking for a way to deal with this:

passed into my script are a number of vars. i know at least one and at most n vars are coming into my script. the issue is that i don't know exactly how many. all these vars will have the following form:

$var for var one
$var1 for var two
$var2 for var three
...
$varn for var n-1

i.e. all these vars start with $var

i want to stick these vars in my session and i know i could do a for loop, but this for loop is really inefficient if n is large.

any ideas on how to get around the for loop?

foreach($HTTP_POST_VARS as $key => $val)
if (substr($key, 0, 3) == 'var')
   $vars[$key] = $val;  // or you can do whatever you need right here.

yep, yep, yep... iterate over only what is passed in. just what i wanted :-) thanks!
