The 'other' guy mentioned that while() is faster than foreach,
is this true?
I read a few days ago somewhere on php.net that foreach() is the
recommended (by php devs) way of iterating over arrays....
also, compare these 2 lines:
while (list(, $idcat) = each($idcats)){ /* ... */ }
foreach ($idcats as $idcat){ /* ... */ }
now its seems to me that the foreach version is 'up' 2 function calls
on the while loop, all else being equal the foreach loop has to be faster
(given that calling functions is relatively very expensive)...
or is foreach() _really_ heavy when compared to while()?
not that I care too much, I find foreach() more pleasing to the eye and there is
less to type (in the given example).

rgds,

what is the best way to explode then loop this string after its taken
apart.
output should be something like:
$id = 4
$cat = gaming
etc..
im just looking for the best/fastest way to do this. the string can grow
to
200 or so bytes, maybe more.
200 bytes is chump-change.
It really doesn't matter how you do this, within reason.
