php word wrap - limiting word size

ChicoMendez

hi

i need to cut long word submitted to a forum im developing

im using

<? echo wordwrap($group->desc, 40, "<br />\n");?>

which seems to work when the text is normal sentances of text - however if someone submits a big long word like below it is not treated at all.

11111111111111111111111111111111111111111111111111111111112222222222222222222222222222222222222222223333333333333333333333333333333333334444444444444444444444444444444444444555555555555555555555555555


anyone know how i could handle this ?

tnx

I'm using the command

if (strlen($text)>30) $text=substr($text,0,30)." ...";

Never seemed to have a problem with it?

yes but this get the length of the string - and not seperate words in that string.. i dont want to shorten teh string i just want to ensure that long words or lines of characters are broken up so as not to break the site !

Look at post #9 in the "PHP - Text Length" thread. I used wordwrap and then explode'd the string into an array.
You could go through each element in the array and further split it if it is longer than the max you want. This further splitting would be quite brute force.

there is a function that I often use to show only a certain amount of text from long description:

[php]
//truncate memo
function TruncateMemo($str, $ln){
if (strlen($str) > 0 && strlen($str) > $ln) {
$str = str_replace("<br />", chr(10), $str); //replace br tag to space for a clean cut
$k = 0;
while ($k >= 0 && $k < strlen($str)){
$i = strpos($str, " ", $k);
$j = strpos($str,chr(10), $k);
if ($i === false && $j === false) { // Not able to truncate
return $str;
} else {
// Get nearest space or CrLf
if ($i > 0 && $j > 0) {
if ($i < $j) {
$k = $i;
}else{
$k = $j;
}
}elseif ($i > 0) {
$k = $i;
}elseif ($j > 0) {
$k = $j;
}
// Get truncated text
if ($k >= $ln) {
return substr($str, 0, $k) . "... ";
} else {
$k ++;
}
}
}
} else {
return $str;
}
}
