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);
}
?>
