I created an alternative using the function imagechar to create a string of an image. The below function below was used to create an image the same height and width of the text string. It is used on my website to mask users email addresses.
<?PHP
// Set your string somehow
$string = '[email protected]';
// Set font size
$font_size = 4;
// Create image width dependant on width of the string
$width = imagefontwidth($font_size)*strlen($string);
// Set height to that of the font
$height = imagefontheight($font_size);
// Create the image pallette
$img = imagecreate($width,$height);
// Grey background
$bg = imagecolorallocate($img, 25, 25, 25);
// White font color
$color = imagecolorallocate($img, 255, 255, 255);
// Length of the string
$len = strlen($string);
// Y-coordinate of character, X changes, Y is static
$ypos = 0;
// Loop through the string
for($i=0;$i<$len;$i++){
// Position of the character horizontally
$xpos = $i * imagefontwidth($font_size);
// Draw character
imagechar($img, $font_size, $xpos, $ypos, $string, $color);
// Remove character from string
$string = substr($string, 1);
}
// Return the image
header("Content-Type: image/gif");
imagegif($img);
// Remove image
imagedestroy($img);
?>
