I have looked through php.net (and googled) without finding an example
of this particular scenario.
If the message is the result of:
$msg = "A very long sentence\n";
$msg .= "A short sentence\n"; // less than 70 characters
$msg .= "Another short sentence\n"; // less than 70 characters
$msg .= "Another very long sentence";
$msg = wordwrap($msg, 70);
Does wordwrap only act on the longer individual strings? Will the short
strings appear on lines of their own?
In other words, will the formatting (\n) in each string taken separately
override the overall wordwrap?
Thank you,
Bill B

No. Is that the standard?
I am using this in a "listening" script that is triggered by receiving a
notice from PayPal. The PayPal information supplies the variables for
the mail function, including the customer's email address. Based on the
transaction type a different message is composed. There are about 10
different messages of differing content and formatting.
That is difficult to test repeatedly so I turned to this group. If you
think that is misguided, then pass on responding.

If you want to know if a function does something specific, the
"standard" is to write a short test script using the function and see if
it works like you think it will.

Noted. So I should look to see that everyone who writes to the group for
help provides such evidence, regardless of the complexity of their
problem. Correspondingly, I should fail to see anyone, especially you,
offering suggestions or help in the absence of such evidence. That about
right?

There is, of course, only one string in your example. (which contains
more sentences....)

Yes, the current 'break' character (3rd paramerer) is not changed, so if
a short 'sentence' is found it will be shorter than the specified width
in the second parameter.

above concluded after a bit of testing ;)

No, but which is easier - writing a five line script to test it
yourself, or composing a question, posting it to usenet and waiting a
day or two for a response?
Your question is so easy to test locally it isn't even funny.

IOW you wrote the test script for him, Luuk? How good of you :)

no, i copied the lines in out of the original post....
and added 'echo $msg;' to the end
oh wait, i made the last sentence a bit longer too.... ;)
And, yes, i'm not a consultant, as you are, so i *know* how to do it.

I *know* how to do it, also. But I also *know* how to get people to
help themselves!

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
