//adv0.jpg就是背景图片,注意函数与图片格式对应
$im = imagecreatefromjpeg('/www/law/images/demo/adv0.jpg');
$font_color = imagecolorallocate ($im, 0, 250, 10); //这是文字颜色，绿色

$text = "张三的博客";                               //文字内容

$font_file = "/www/font/hyi_xkj.ttf";               //字体的linux绝对路径

//26：字体， 0 是角度， 10，36是坐标， $font_color是文字色， font是字体，文本是填入的文字
imagettftext($im, 26,0, 10, 36, $font_color ,$font_file, $text); 往图片插入文字

// output image
header ('content-type: image/png');                 //即便是从jpg拷贝的图片，也能以png输出，
imagepng ($im);
// clean up
imagedestroy($im);
