MUBA,
Ok - yes and no - depends on how you look at it. One is usually referred to as a C-style for loop (does not localize $_ or implicitly alias looping variable) and the other is typically referred to as a foreach loop (which does both of those things).
for ( $i = 0; $i < 10; $i++ ) {
# C-style but could also say foreach
}
foreach ( @array ) {
# Localizes $_ and implicitly aliases looping variable
# Could also just be for
}
In your code, it does not matter which name you use. It is the looping construct that follows the name that determines the internal behavior.

Camel Book, 3rd Edition, page 118 says, "The foreach keyword is just a synonym for the for keyword, so you can use for and foreach interchangeably, whichever you think is more readable in a given situation."
So you could do:
#!/usr/bin/perl
use strict;
my @array = qw(one two three four);
print "Foreach:\n";
foreach my $item (@array) {
print "$item\n";
}
print "\nFor:\n";
for my $item (@array) {
print "$item\n";
}

Check out for, this has been discussed many times before -- get to know super search. | [reply] |
for and foreach are the same.
