How is speed affected in the following scenarios:
1) Using a number of if statements
i.e.
while ($foo) {
do_1() if ($condition_1);
do_2() if ($condition_2);
# ...
}
2) Using a series of if elsifs
i.e.
while ($foo) {
if ($condition_1) {
do_1();
}
elsif ($condition_2) {
do_2();
}
# ...
}
3) using a series of if elsifs and calling next:
i.e.
while ($foo) {
if ($condition_1) {
do_1();
next;
}
elsif ($condition_2) {
do_2();
next;
}
# ...
}
For readability, I prefer 1 over 2. But I figured 2 would be faster
then 1. For readability I prefer 2 over 3, but I figure the lasts would
be implied in #2. Is this the case? Or should I bite the bullet and
use 3?
Thanks in advance,
Dan
