Many folks want to generate text to an image. The PHP GD lib allows us to do just this. Here we show a simple method to turn an email address into an image for use on a web page. Some say this helps to keep the email harvesters away, but with optical character recognition this is still possible.


// show the correct header for the image type
header("Content-type: image/jpg");

// an email address in a string
$string "email@example.com";

// some variables to set
$font  4;
$width  ImageFontWidth($font) * strlen($string);
$height ImageFontHeight($font);

// lets begin by creating an image
$im = @imagecreatetruecolor ($width,$height);

//white background
$background_color imagecolorallocate ($im255255255);

//black text
$text_color imagecolorallocate ($im000);

// put it all together
imagestring ($im$font00,  $string$text_color);

// and display
imagejpeg ($im);
