in thread Printing contents of file on a HTML page.

Thanks this did work for me except it prints out the file contents on one line in my HTML page:
wordOnewordTwowordThree Okay this prints out.
It should print out:
wordOne wordTwo wordThree Okay this prints out.
Here is what I used and it works but how can I make the output print the correct way? I have tried the "\n" and <br> in various places but no luck.
use strict; my $path = "/web/webpage.html"; my $myfile = "/perl/bin/bas.txt"; open FIL, "$myfile" || die "cant open: $!\n"; open OUT, ">$path" || die "Can't open $path for writing: $!\n"; while (<FIL>) { print OUT; } print OUT <<"EOF"; <html> <head> <title>Title</title> </head> <body> <br> Okay this prints out. </body> </html> EOF close OUT || die "Can't close filehandle: $!\n"; close FIL || die "no cant close: $!\n";

    There are many possible solutions for this. One is:

    print OUT "<pre>"; while (<FIL>) { print OUT; } print OUT "</pre>";
      print map{$_.'<br>'}<FIL>;

[Corion]: hippo: If you have a Unicode-wise Perl then likely some zero-width characters in $x would work. Maybe $x = "\x{200b}" works.
[Corion]: Hmm - no, that outputs 1 for me on 5.14 - perl -wle "my $x = qq(\x{200b}); warn $x; warn length $x"
[hippo]: Smart - I'll give that a go. Thanks.
[hippo]: Ah
[Corion]: But maybe there is some other Unicode string that will be true but have a zero width
[hippo]: For explanation, I've seen this construct in someone else's code (no names, no pack drill) and couldn't think of a situation to trigger it.
[Corion]: You'll have to look somewhere esoteric for that. Maybe some tied variable or special dualvar can also trigger that. But it's certainly not a common occurrence
[Corion]: And on 5.20, the following also outputs no find:perl -wle 'for my $x ("\x{2000}".."\ x{1fffff}") { if( $x && ! length $x ) { warn qq(<$x>); warn length $x; die } }'
[Corion]: (this time on Unix)
[hippo]: Understood. I'll have to go through the code and see if it's doing anything fancy with ties, dual-vars or non-scalars. In the end, it's probably a bug though.
