note 86134 modified in function.imagettfbbox by danbrown

This is a function which reformats a text string into a text block of a given width.
Usefull when you have a long single line string and want to fit it into a fixed width but don't care about it's height

<?php
function makeTextBlock($text, $fontfile, $fontsize, $width)
{	
	$words = explode(' ', $text);
	$lines = array($words[0]);
	$currentLine = 0;
	for($i = 1; $i < count($words); $i++)
	{
		$lineSize = imagettfbbox($fontsize, 0, $fontfile, $lines[$currentLine] . ' ' . $words[$i]);
		if($lineSize[2] - $lineSize[0] < $width)
		{
			$lines[$currentLine] .= ' ' . $words[$i];
		}
		else
		{
			$currentLine++;
			$lines[$currentLine] = $words[$i];
		}
	}
	
	return implode("\n", $lines);
}
?>
