A modified version of your sample that does what I mean:
#!/usr/bin/perl -w use strict; use URI::Escape; use HTML::Entities; use CGI qw/:standard/; use CGI::Carp 'fatalsToBrowser'; print header; my $file; if(param('test')){ my $code = param('test'); $code = uri_unescape($code); $code = encode_entities($code); open STDERR, '>&STDOUT'; eval $code; print $@ if $@; }

No need to create external, temporary files. There are some potential messy issues in there, but this is good enough for rough cut.

[james28909]: it is not an absolute date like "27" or "31". sometimes it is like wednesday or friday
[james28909]: and i need to format those special instances into an absolute date instead of "yesterday"
[stevieb]: ask a question on SoPW, and include at least a half-dozen examples of the input, and at least one example of expected output
[davido]: Exactly: SoPW. This isn't going to be solved easily in the CB.
[james28909]: in need "yesterday" and so on, to be absolute like "1" or "31"
[stevieb]: ...and throw some of your existing code into the equation as well, just so readers know you've given a try at it ;)
[james28909]: ok
[stevieb]: davido thanks for the link ;) I was being the typical lazy
[davido]: date parsing is hard. The more examples you can provide of the input (within reason) and expected output, the better.
[stevieb]: agreed. That's why I said at least a half-dozen. If enough of the different formats are present, the date/time folk may not have to request more. If they do, then at least there was a decent base to start with
