在图像上添加文字

在图像上添加文字。我有两个代码，分别工作。第一个用于通过pdo连接将图像上载到服务器和数据库。第二个被用来为静止图像加水印。在图像上添加文字

我的问题是，我想结合这两个代码，以文本水印图像上传到服务器时没有全球变量的帮助。我一直在努力，但不能得到它的工作。有人可以帮助我整合这一点。谢谢

<?php 
include('pdo.php'); 
    if (!isset($_FILES['image']['tmp_name'])) { 
    echo ""; 
    }else{ 
    $file=$_FILES['image']['tmp_name']; 
    $image= addslashes(file_get_contents($_FILES['image']['tmp_name'])); 
    $image_name= addslashes($_FILES['image']['name']); 
    $image_size= getimagesize($_FILES['image']['tmp_name']); 
if ($image_size==FALSE) { 
     echo "That's not an image!"; 
      }else{ 
      move_uploaded_file($_FILES["image"]["tmp_name"],"postphoto/" . $_FILES["image"]["name"]); 
      $location="postphoto/" . $_FILES["image"]["name"]; 
      $from=$_POST['from']; 
      $time=time(); 
      $photos='photos'; 
$statement = $db->prepare('INSERT INTO text_watermark (photo,from_send) values(:photo,:from_send)'); 
if(!$statement->execute(array( 
':photo' => $photos, 
':from_send' => $from))){ 
       echo 'There is problem';  
      } 
      else{ 
      header("location: lol.php"); 
      exit(); 
      } 
      } 
    } 
?> 


<?php 
     //Set the Content Type 
     header('Content-type: image/jpeg'); 
     // Create Image From Existing File 
     $jpg_image = imagecreatefromjpeg('sunset.jpg'); 
     // Allocate A Color For The Text 
     $white = imagecolorallocate($jpg_image, 255, 255, 255); 
     // Set Path to Font File 
     $font_path = 'font.TTF'; 
     // Set Text to Be Printed On Image 
     $text = "This is a sunset!"; 
     // Print Text On Image 
     imagettftext($jpg_image, 25, 0, 75, 300, $white, $font_path, $text); 
     // Send Image to Browser 
     imagejpeg($jpg_image); 
     // Clear Memory 
     imagedestroy($jpg_image); 
    ?>

在发布后看看你的问题。然后在代码中修复完全不必要的空白。 –

所有的空格已被删除 – Sectona

只是离开也正确缩进代码 –

如果你的代码是正确的，它只是一个移动块的情况。你可能想考虑当某人上传一个PNG时会发生什么。虽然你可能会在其他地方捕捉这个..
