Text wrap for imagettftext

One line text does not always fit into a given width of the picture, then you need to word wrap the text to a new line, depending on the width. If only the width is less than one word, then you will need a shaman's drum and witchcraft. PHP code to create a picture of the text with a given width:

//content type
header('Content-Type: image/png');

$font = 'arial.ttf';
//font size
$font_size = 10;
//image width
$width = 100;
//text margin
$margin = 5;

$text = "That is why where when why and how, and now why where when why and how?";

//explode text by words
$text_a = explode(' ', $text);
$text_new = '';
foreach($text_a as $word){
	//Create a new text, add the word, and calculate the parameters of the text
	$box = imagettfbbox($font_size, 0, $font, $text_new.' '.$word);
	//if the line fits to the specified width, then add the word with a space, if not then add word with new line
	if($box[2] > $width - $margin*2){
		$text_new .= "\n".$word;
	} else {
		$text_new .= " ".$word;
//trip spaces
$text_new = trim($text_new);
//new text box parameters
$box = imagettfbbox($font_size, 0, $font, $text_new);
//new text height
$height = $box[1] + $font_size + $margin * 2;

//create image
$im = imagecreatetruecolor($width, $height);

//create colors
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);
//color image
imagefilledrectangle($im, 0, 0, $width, $height, $white);

//add text to image
imagettftext($im, $font_size, 0, $margin, $font_size+$margin, $black, $font, $text_new);

//return image
//frees any memory associated with image

    Good job man....!
    Can you write this code in single line with fix height width we can adjust letter spacing according to text.

  3. This is exactly what I have been looking for. Thanks. I have added it a script I use when I add Founding Father quotes to my site. It will automatically generate a Meme to use for sharing on Facebook, etc. Thanks for sharing your knowledge with the rest of us. You saved me a lot of time.

  4. Thanks!
