Generate artistic font image watermark code_PHP tutorial

//adv0.jpg is the background image, please note that the function corresponds to the image format
$im = imagecreatefromjpeg('/www/law/images/demo/adv0.jpg');
$font_color = imagecolorallocate ($im, 0, 250, 10); //This is the text color, green

$text = "Zhang San's blog"; 
$font_file = "/www/font/hyi_xkj.ttf"; //The linux absolute path of the font

//26: font, 0 is the angle, 10, 36 are the coordinates, $font_color is the text color, font is the font, and the text is the filled in text
imagettftext($im, 26,0, 10, 36, $font_color ,$font_file, $text); Insert text into the picture

// output image
header ('content-type: image/png');                                                // Even pictures copied from jpg can be output as png,                                   imagepng ($im);
// clean up
imagedestroy($im);
