php - 向图像添加文本后如何保存图像

Question

为了向图像添加文本，我使用网站中的以下代码

<?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);
?> 

它运行良好，但我无法保存在图片中以保存文本文件，我正在使用它功能

function write($post,$myFile){
    $fh = fopen($myFile, 'a+') or die("can't open file");
    fwrite($fh, $post);
    fclose($fh);
} 

有什么办法可以将图像保存为 jpg 格式吗？

检查此代码。它与您的代码相同，唯一的区别是

imagejpeg($jpg_image,"imagefolderpath/image.jpg");

而不是imagejpeg($jpg_image);
也许对你有帮助。

<?php
  header('Content-type: image/jpeg');
  $jpg_image = imagecreatefromjpeg('sunset.jpg');
  $white = imagecolorallocate($jpg_image, 255, 255, 255);
  $font_path = 'font.TTF';
  $text = "This is a sunset!";
  imagettftext($jpg_image, 25, 0, 75, 300, $white, $font_path, $text);
  imagejpeg($jpg_image,"imagefolderpath/image.jpg");
  imagedestroy($jpg_image);
?>
