hey, I have made a shoutbox in php, however i have one problem.

when the word/sentence they have entered exceeds the size of the link it just adds a scroll bar at the bottem and make one big long line, which is making my shout box format muck up.

Is there anyway i can edit my script OR is there a script i can use to validate the length ...

eg ...

after 100 character has been typed and automatic <br> is added etc.

whats wrong with wordwrap

 

<?php
$text = "The quick brown fox jumped over the lazy dog.";
$newtext = wordwrap($text, 20, "<br />\n");

echo $newtext;
?>

 

 

 

<?php
/**
* function wordCut($sText, $iMaxLength, $sMessage)
*
* + cuts an wordt after $iMaxLength characters
*
* @param  string   $sText       the text to cut
* @param  integer  $iMaxLength  the text's maximum length
* @param  string   $sMessage    piece of text which is added to the cut text, e.g. '...read more'
*
* @returns string
**/    
function wordCut($sText, $iMaxLength, $sMessage)
{
   if (strlen($sText) > $iMaxLength)
   {
       $sString = wordwrap($sText, ($iMaxLength-strlen($sMessage)), '[cut]', 1);
       $asExplodedString = explode('[cut]', $sString);
      
       echo $sCutText = $asExplodedString[0];
      
       $sReturn = $sCutText.$sMessage;
   }
   else
   {
       $sReturn = $sText;
   }
  
   return $sReturn;
}
?>

	//Prepare the name
	$shout = trim($shout);
	$shout = stripslashes($shout);
	$shout = str_replace ("\n", " ", $shout);
	$shout = str_replace ("\r", " ", $shout);
	$shout = str_replace ("\r", " ", $shout);
	$shout = wordwrap($shout, 100, "<br />"); //added
