Re^2: Pass Matched Variable into Regex Replace Variable

I feel like I've tried that and it didn't work.

perl -e '$t="begin{foobar}";$p="begin{(.*?)}";$r="\"end{\$1}\""; $t=~s/$p/$r/gee; print "$t\n\n"'
#Output: end{foobar}

Perhaps I'm doing something wrong? Edit:I didn't escape the dollar sign in the variable. The suggestion works. I'll apply it to my program and see if everything works :) Thank you!

$r="\"end{$1}\""; The double quotes interpolate the `$1`. Use `$r=q("end{$1}")` in this case.	[reply] [d/l] [select]

I actually did that in my production code, but it's worth mentioning for reference. :) cheers	[reply]
