wordwrap with a twist?

I need to wrap text with a negative indent, that is this:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

gives this:


Lorem ipsum dolor sit amet, consectetur adipisicing
elit, sed do eiusmod tempor incididunt ut
labore et dolore magna aliqua.
Ut enim ad minim veniam, quis nostrud exercitation
ullamco laboris nisi ut aliquip ex ea commodo
consequat.
Duis aute irure dolor in reprehenderit in voluptate
velit esse cillum dolore eu fugiat nulla pariatur.
Excepteur sint occaecat cupidatat non proident,
sunt in culpa qui officia deserunt mollit anim id
est laborum.

Is there a clever way to do this? All I can come up with is to parse
painfully the strings word-by-word and count the characters, which on a
long list (hundreds, possiblyly thousands of lines) is quite resource-
intensive.

(the indent can be tabs or spaces, it does not matter)

Thanks,

Pierre

try this....
http://au.php.net/manual/en/function.wordwrap.php


then do a search/replace for each "\n" replacing it with "\t\n".

havent tried it, but should be fairly simple.... i think.

OK. i tried this....

<?php

$v_1 = "Lorem ipsum dolor sit amet, consectetur adipisicing elit,
sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.";
$v_1 = wordwrap ( $v_1, 50, "\n", 1);
echo "<pre>\n";

// do some kinda loop here to get your parapraphs/sentences out of each
string.

$v_1 = str_replace ( "\n", "\n\t", $v_1);
echo $v_1;

// end some kinda loop


echo "</pre>\n";
?>

*negative indent* is the crucial phrase.

All this does is shift the first wrapped line to the left, however it is
still only the same size as the others' text, while it should be longer:

XXXXXXXXXXXXXXXXXXXXX
YYYYYYYYYYYYYYYYY
ZZZZZZZZZZZZZZZZZ

The solution turns out to chop off the start of the text, wordwrap and add
the tabs, then add back the chopped piece at the start of line one.

Not sure what you mean by *negative indent*

.... but I did want to give it another go anyway. this is what I came up
with....

<?php

$v_indent = 4; // the size of the indent in characters
$v_wrapat = 50; // the wrap line at size
$v_nl = "\n";

$v_full_story = "Lorem ipsum dolor sit amet, consectetur adipisicing
elit, sed do eiusmod tempor incididunt ut labore et dolore magna
aliqua.";

$v_paragraphs = explode ( $v_nl, $v_full_story);
echo "<pre>" . $v_nl;

reset($v_paragraphs);
while (list($key, $v_paragraph) = each($v_paragraphs)) {

$v_firstline = substr ( $v_paragraph, 0, $v_indent + $v_wrapat);

$v_restlines = substr ( $v_paragraph, $v_indent + $v_wrapat);

$v_restlines = wordwrap ( $v_restlines, 50, $v_nl, 1);
echo $v_firstline . $v_nl;
$v_restlines = str_replace ( $v_nl, $v_nl . " ",
$v_restlines);
echo " " . $v_restlines;
}

echo $v_nl . "</pre>" . $v_nl;
?>

and then i thought about it, and got this...

*Attempt 234* (and counting)

i think this will do the trick.


<?php

$v_indent = 3;
$v_wrapat = 40;
$v_nl = "\n";
$v_dent = "";

$v_i = 0;
while ($v_i < $v_indent) {
$v_dent = $v_dent . " ";
$v_i++;
}

$v_full_story = "This will wrap the first line of each paragraph at
character $v_wrapat or earlier. Each subsequent line will be wrapped
at character $v_wrapat less $v_indent. The \"less $v_indent\" takes
into account the extra characters placed before each of the lines for
the actual indent.

indent.";

$v_paragraphs = explode ( $v_nl, $v_full_story);
echo "<pre>" . $v_nl;

reset($v_paragraphs);
while (list($key, $v_paragraph) = each($v_paragraphs)) {

$v_firstline = wordwrap ( $v_paragraph, $v_wrapat, $v_nl, 1);
$v_temp = explode ( $v_nl, $v_firstline);
$v_firstline = $v_temp[0];

$v_len = strlen ($v_firstline);
$v_restlines = substr ( $v_paragraph, $v_len + 1);

$v_restlines = wordwrap ( $v_restlines, $v_wrapat - $v_indent -
1, $v_nl, 1);
echo $v_firstline . $v_nl;
$v_restlines = str_replace ( $v_nl, $v_nl . $v_dent,
$v_restlines);
echo $v_dent . $v_restlines;
}

echo $v_nl . "</pre>" . $v_nl;
?>
