i got this script to generate an image out of a random jpg in a directory, adding a random slogan from a database:
<?php
header('Content-type: text/html; charset=utf-8');
include '../connect.php';
require_once 'random.php';
$timestamp = time();
$date = date("d.m.Y_G", $timestamp);
$slogan = $mysqli->query("SELECT `text` FROM `slogans` ORDER BY RAND() LIMIT 1");
$slogan_txt = $slogan->fetch_assoc();
$bg = get_rand_img('../../images/');
$imgPath = '../../images/' .$bg;
$text = $slogan_txt[text];
$image = $imgPath;
$font = "font.TTF";
$font_size = "25";
$image_2 = imagecreatefromjpeg($image);
$black = imagecolorallocate($image_2,0,0,0);
$image_width = imagesx($image_2);
$image_height = imagesy($image_2);
$text_box = imagettfbbox($font_size,$angle,$font,$text);
$text_width = $text_box[2]-$text_box[0]; // lower right corner - lower left corner
$text_height = $text_box[3]-$text_box[1];
$x = ($image_width/2) - ($text_width/2);
$y = ($image_height/2) - ($text_height/2);
imagettftext($image_2,$font_size,0,$x,$y,$black,$font,$text );
header ("Content-type: image/png");
imagejpeg($image_2);
?>
works fine so far.
Now there are some slogans with to much words for one row. i need them to be wrapped and also be centered!
can't use wordwrap in imagettftext(), so i need to explode it somehow.
i found some functions on the web, but they dont work as expected. maybe i just dont know how to combine them with my existing code!
maybe someone got a workign example from own projects?
thanks so far!
