word search and wrap crisis

[kenny873]

i have a forum and I would like to perform the following task:

when user post a message as follow:

"heydudehereisthephotoyouwouldliketoread...checkitoutheydudehereisthephotoyouwouldliketoread...checkitoutheydudehereisthephotoyouwouldliketoread...checkitoutheydudehereisthephotoyouwouldliketoread...checkitoutheydudehereisthephotoyouwouldliketoread...checkitout

howdoyoulikeitpleaseletmeknowhowdoyoulikeitpleaseletmeknowhowdoyoulikeitpleaseletmeknowhowdoyoulikeitpleaseletmeknow."

I want the words to be in wordwrap where i did wordwrap function, but then if I want to post this picture, the wordwrap function will break the url of the picture with a % and hence, the picture will not be shown. I would like to write a function the will search each word in the messge and when it sees "http://" it will not wrap the area of "http://........." but the other words will be wrapped.

how do I do it?

I wrote this function earlier this year for someone else. What it does is wordwraps any word that is longer than your specified character length, without wrapping the rest of them. Comes in pretty handy. You could just use this, and set the $iMax variable to a very long enough value, or you could use something like a preg_split() on the <img> tag to split the text up into an array, then your even keys of the array will be text, and your odd keys will be the img links. You could even combine the 2 methods! So many possibilities 🙂

	
function split_words($sInput, $sDelim="\n", $iMax=20) {

$aWords = explode(" ", $sInput);

// Loop through the array created by explode
foreach($aWords as $sLongWord) {

	// Check the length of the word
	if(strlen($sLongWord) > $iMax) {

		// If this ISN'T the first word put in a newline before the long word
		if(!empty($sOutput)) {

			$sOutput .= $sDelim;
		}

		// Loop through the word itself, splitting it up using substr
		for($i=0; ($i*$iMax) < strlen($sLongWord); $i++) {

			// the offset is needed to get the right part of the word
			$iOffset = $i*$iMax;
			$sOutput .= substr($sLongWord, $iOffset, $iMax).$sDelim;
		}    
	// Else, just display the word with a space before hand (explode will strip the spaces)
	} else {

		$sOutput .= " ".$sLongWord;
	}
}

return $sOutput;
}
