In this tutorial I will show you how to transform text into an image using PHP.
To show the text you need to go to the php file in your web browser and type ?text=words on the end of it. For example: www.yoursite.com/pageurl.php?text=words” This will then show “words” as an image.
You can be lazy and just copy and paste the code below or you can look at a code breakdown below.
header("Content-type: image/png");
$text = stripslashes($_GET['text']);
$number = strlen($text);
$number = ($number*7)+9;
$im = imagecreate($number, 24);
$colour1 = imagecolorallocate($im, 0, 0, 0);
$colour2 = imagecolorallocate($im, 255, 255, 255);
imagestring($im, 3, 5, 5, $text, $colour2);
imagepng($im);
imagedestroy($im);
Code Breakdown
Code Breakdown
header("Content-type: image/png");
Tells the browser to show an image, not a .php file.
$text = stripslashes($_GET['text']);
Take the text and stop it from messing up with ‘
$number = strlen($text);
This counts the amount of characters in the text.
$number = ($number*7)+9;
Times this by 7 and add 9 to make it look the right size.
$im = imagecreate($number, 24);
Create the basic size, $number x 24
$colour1 = imagecolorallocate($im, 0, 0, 0);
Makes the background black (RGB) Change these to change the background colour to what ever you like.
$colour2 = imagecolorallocate($im, 255, 255, 255);
Makes the text white. Again, change these numbers to get the colour you want.
imagestring($im, 3, 5, 5, $text, $colour2);
Adds the text to the image
imagepng($im);
Creates and displays the image
imagedestroy($im);
This destroys the image after it has been used. If this is not used after a while your server will begin to lag.
