I noticed you guys better wordwrap was erasing some characters so I changed it, namely the line:
substr($str,0,$i-1).$cut.substr($str,$i,$str_len-1);
Hope its of some use.
function even_better_better_wordwrap($str,$cols,$cut) {
$tag_open = '<';
$tag_close = '>';
$count = 0;
$in_tag = 0;
$str_len = strlen($str);
$segment_width = 0;
for ($i=0 ; $i<=$str_len ; $i++){
if ($str[$i] == $tag_open) {
//tamos dentro de uma tag html
$in_tag++;
} elseif ($str[$i] == $tag_close) {
//fechamos uma tag html
if ($in_tag > 0)
$in_tag--;
} else {
if ($in_tag == 0) {
//se nao estamos dentro de uma tag html
$segment_width++;
if (($segment_width > $cols) && ($str[$i] != " ")) {
//se passamos o limite de colunas acrescentamos o $cut no sitio
$str = substr($str,0,$i-1).$cut.substr($str,$i,$str_len-1);
$i += strlen($cut);
$str_len = strlen($str);
$segment_width = 0;
}
}
}
}
return $str;
}
