PHP图片和文字合成函数刚刚出炉

public function createOnlineCourseCertsImgFront()
     {
         //照片
         $path_2=ROOT_PATH . 'public/uploads/certsimg/12.png';
         
         //背景图片
         $path_1 = ROOT_PATH . 'public/uploads/certsimg/11.png';
 
         //创建图片对象
        $image_1 = imagecreatefrompng($path_1);
        $image_2 = imagecreatefrompng($path_2);
        
        //合成图片
        imagecopymerge($image_1, $image_2, 49, 111, 0, 0, imagesx($image_2), imagesy($image_2), 100);
        
        //这是要插入到图片的文字
        $name = '李天一';
        $idnum = '00000001';
        $validtime = '2020-10-31';
        $sex='男';
        $certtime='2020-05-26';
        
        //文件名
        $filename="temp";
        
        //设置文字颜色
        $black = imagecolorallocate($image_1, 0, 0, 0);
        
        //写的文字用到的字体
        $font = ROOT_PATH . 'public/uploads/certsimg/simfang.ttf';
        
        //在图片里插入文字$black
        imagettftext($image_1, 20, 0, 339, 130, $black,$font, $name);
        imagettftext($image_1, 20, 0, 555, 130, $black,$font, $sex);
        imagettftext($image_1, 20, 0, 339, 188, $black, $font, $idnum);
        imagettftext($image_1, 20, 0, 339, 243, $black, $font, $certtime);
        imagettftext($image_1, 20, 0, 339, 293, $black, $font, $validtime);
        
        //这是合成后的图片保存的路径
        $upload_dir = "public/uploads/certsimg/"; 
        
        imagepng($image_1, ROOT_PATH . $upload_dir . $filename . '.png');
     
        $finalurl='uploads/certsimg/'.$filename . '.png';
        
        return  $finalurl;
          
     }

效果图如下
