how do i make some texts as image file on the fly ? i have some data in db ( text format normally a text dump ) and i want that to convert to an image and display whenever a query is made any libraries/class files are there for this purpose
this is not just string it can contain lot of utf-codes and its multiple lines too the \n are going to display as \n instead of newline with such examples
Hi, I use this small script to generate a random number and then convert it to image : <?php session_start(); // generate 5 digit random number $rand = rand(10000, 99999); // create the hash for the random number and put it in the session $_SESSION['image_random_value'] = md5($rand); // create the image $image = imagecreate(60, 30); // use white as the background image $bgColor = imagecolorallocate ($image, 255, 255, 255); // the text color is black $textColor = imagecolorallocate ($image, 0, 0, 0); // write the random number imagestring ($image, 5, 5, 8, $rand, $textColor); // send several headers to make sure the image is not cached // taken directly from the PHP Manual // Date in the past header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // always modified header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // HTTP/1.1 header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); // HTTP/1.0 header("Pragma: no-cache"); // send the content type header so the image is displayed properly header('Content-type: image/jpeg'); // send the image to the browser imagejpeg($image); // destroy the image to free up the memory imagedestroy($image); ?> PHP: You can use another function (or you can call a number from your database) instead of $rand = rand(10000, 99999); of course. Then use a html <img> tag and set <img src='path_to_the_abowe_script.php'>.
