This thread was helpful to me by revealing the existence of the wordwrap
function, which will be helpful to me. But what I'd like to be able to do is
also indent each line by a certain number of characters. I'm sure this can
be done by replacing all occurrences of the newline character with a newline
and the number of spaces desired, although it would also need to be inserted
at the start of the first line. I found a Perl script that does this:

# Find length of longest field name, for formatting; include space for
colon
my $maxlength= 0 ;
foreach (keys %in) {
$maxlength= length if length > $maxlength ;
}
$maxlength++ ;

foreach ('Full_Name', 'Email', 'Event_Title','Event_Date','Event_Time',
'Event_Description') {

# If a field has newlines, it's probably a block of text; indent it.
if ($in{$_}=~ /\n/) {
$in{$_}= "\n" . $in{$_} ;
$in{$_}=~ s/\n/\n /g ;
$in{$_}.= "\n" ;
}

# comma-separate multiple selections
$in{$_}=~ s/\0/, /g ;

# Print fields, aligning columns neatly
printf MAIL "%-${maxlength}s %s\n", "$_:", $in{$_} ;
}

I will try to rewrite this in PHP, and it may be a good learning experience
since I am not fluent with RegEx. But if there is a better way, I'd
appreciate some tips.

Thanks,

Paul
