How to Convert Medium Text to JPG in PHP

The PHP language includes a function that makes images from text. You convert the text to a JPG image using the imagejpeg function. The function lets you set the size and color of the text to fit a specified height and width. You use this function when you want to create automated images from a user's input on a Web page.

Instructions

1. Right-click the PHP file you want to edit. Click "Open With" and select your preferred PHP editing program.

2. Set up the medium-sized text. The image function supports small, medium and large text, but you must specify the size with your image setup function. The following code creates the text "Hello World":

   $im = imagecreatetruecolor(120, 20);
   $color = imagecolorallocate($im, 233, 14, 91);
   imagestring($im, 1, 5, 5, 'Hello World', $color);

   In this example, the image is set up with red text, and the size is 120 pixels in width by 20 pixels in height.

3. Output the image to the user's screen and convert the image to JPG format. The following code uses the Hello World text to create the JPG:

   header('Content-Type: image/jpeg');
   imagejpeg($im);
