Question

图片没有显示，甚至没有显示文字。我无法找到错误。是否需要在其中添加额外的插件或库文件？

   <?php
  //Set the Content Type
  header('Content-type: image/jpeg');

  // Create Image From Existing File
  $jpg_image = imagecreatefromjpeg('test.jpg');

  // Allocate A Color For The Text
  $white = imagecolorallocate($jpg_image, 255, 255, 255);

  // Set Path to Font File
  $font_path = 'typesimp.TTF';

  // Set Text to Be Printed On Image
  $text = "Hello World!!";

  // 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);
 ?>

您是否添加了内容类型？

//Set the Content Type
header('Content-type: image/jpeg');

如何在PHP中的图像上写文字？
