[RESOLVED] Printout problem

[Studio381]

I've got an application that prints out to a file in PDF fomat.
The PDF routine I'm using truncates the input strings if they are over approx 100 characters.
So I wanted to check the input strings (length unknown) and split them before calling the PDF routine.
I'd thought of something like...

$workingstring = $_POST[inputstring];
while (strlen($workingstring)>90
{$printstring=substr($workingstring(0,90);
$pdf->Cell(0,10,$printstring,0,1);
$workingstring=substr_replace($workingstring,"",0,90);
}
$pdf->Cell(0,10,$workingstring,0,1);

This (assuming it works, I haven't tried it yet) has the drawback that it splits the string after 90 characters which could be in the middle of a word and I'd much rather split the string after eg 85 or 94 characters to avoid splitting words.

Can anyone show me a better way to do this?

Thanks,
John.

Here's a function I use to shorten articles to a specified length without breaking words and append an ellipsis to the end unless the last character was a period, question mark, or exclamation point (e.g. the end of a sentence):

function shortText($string, $length, $ellipsis = " ...") { 
	$words = explode(' ', $string); 
	$curindex = $wcount = 0;
	foreach($words as $value) { 
		$wcount += strlen($value)+1; 
		if($wcount>$length-strlen($ellipsis))
			break; 
		$curindex++; 
	}
	$newStr = implode(' ', array_slice($words, 0, $curindex));
	return $newStr . (in_array($newStr[strlen($newStr)-1], array('.', '?', '!')) ? ' ' : $ellipsis); 
}

It could be simplified a lot if you don't need all of that functionality.
