You are looking in the wrong area.. I'm working with php3.

Here is what I see... and if you count the brackets, there are 15.. ?

A quick and dirty function to wrap text at a given wrap margin:
function wraptext($text, $wrapmargin)
{
$rettext = "";
$linebuf = "";
$linelen = 0;
$tok = split("[ \t]", $text);
$numtok = count($tok);
for ($i = 0; $i < $numtok; $i++)
{
$elem = $tok[$i];
$elemlength = strlen($elem) + 1;
if ($linelen + $elemlength > $wrapmargin)
{
$rettext = $rettext . $linebuf . "\n";
$linebuf = "";
$linelen = 0;
}
// Do we have a newline in this element?
$pos = strrpos($elem, "\n");
if ($pos)
{
$before = substr($elem, 0, $pos);
$after = substr($elem, $pos);
$rettext = $rettext . $linebuf . " " . $before . "\n";
$linebuf = $after;
$linelen = strlen($after);
}
else
{
$linebuf = $linebuf . " " . $elem;
$linelen = $linelen + $elemlength;
}
}
// Do we have a newline in this element?
$pos = strrpos($elem, "\n");
if ($pos)
{
$before = substr($elem, 0, $pos);
$after = substr($elem, $pos);
$rettext = $rettext . $linebuf . " " . $before . "\n";
$linebuf = $after;
$linelen = strlen($after);
}
else
{
$linebuf = $linebuf . " " . $elem;
$linelen = $linelen + $elemlength;
}
}
return $rettext;
}
