Re: using foreach with a regex

i want to know how i can use "foreach" Loop in this situation instead of the "for" loop

for and foreach are exact synonyms, so whenever you can one, you can also use the other instead.

But maybe it's easier to use while ($string =~ /regex/g) { ... } instead of the combination of for and </c> (unless you want to limit the number of possible matches).

whenever you can one, you can also use the other instead. Almost. `>perl -le"sub for { print 1 } sub foreach { print 2 } &for;" 1 >perl -le"sub for { print 1 } sub foreach { print 2 } &foreach;" 2` [download] and `>perl -le"print 'for';" for >perl -le"print 'foreach';" foreach` [download] This post is not to be taken seriously :)	[reply] [d/l] [select]

Well, you cannot (unless you want to include fatal (run time) errors in 'not getting the same result'). `$ perl -wE 'sub for {say "Hello"} &for' Hello $ perl -wE 'sub foreach {say "Hello"} &for' Undefined subroutine &main::for called at -e line 1.` [download]	[reply] [d/l]
