Question

我正在尝试将php输出内容保存为图像。

以下是示例

http://p1.followland.com/namegenerator/imagen.php?1=95&2=47&3=32&4=88&5=50&name=OLIVIA&g=0

如果有其他方式，我的代码很长，请告诉我。我会批评那个

下面是我的代码。

     <?php
     $v = (int)$_GET['v'];
     $w = (int)$_GET['w'];
     $x = (int)$_GET['x'];
     $y = (int)$_GET['y'];
     $z = (int)$_GET['z'];

   $font_size_offset = 9.25; // you'll have to play with this, to get it just right.
                      // alter it based on the size of the font you use for #label.

    ?>

     <style type="text/css">

   body { 
background-image: url('wo.jpg');
background-repeat: no-repeat;
background-attachment: fixed;
background-position: 0px 0px;

示例中的代码包含css和html。通常，服务器会将其发送到浏览器，浏览器会将其转换为屏幕上的图像。服务器不提供浏览器的布局功能。在PHP中，您可以自己进行布局，并对下面的代码执行类似的操作（信用http://adaptive-images.com）

<?php
function sendErrorImage($message) {
  /* get all of the required data from the HTTP request */
  $document_root  = $_SERVER['DOCUMENT_ROOT'];
  $requested_uri  = parse_url(urldecode($_SERVER['REQUEST_URI']), PHP_URL_PATH);
  $requested_file = basename($requested_uri);
  $source_file    = $document_root.$requested_uri;

  $im            = ImageCreateTrueColor(800, 300);
  $text_color    = ImageColorAllocate($im, 233, 14, 91);
  $message_color = ImageColorAllocate($im, 91, 112, 233);

  ImageString($im, 5, 5, 5, "Adaptive Images encountered a problem:", $text_color);
  ImageString($im, 3, 5, 25, $message, $message_color);

  ImageString($im, 5, 5, 85, "Potentially useful information:", $text_color);
  ImageString($im, 3, 5, 105, "DOCUMENT ROOT IS: $document_root", $text_color);
  ImageString($im, 3, 5, 125, "REQUESTED URI WAS: $requested_uri", $text_color);
  ImageString($im, 3, 5, 145, "REQUESTED FILE WAS: $requested_file", $text_color);
  ImageString($im, 3, 5, 165, "SOURCE FILE IS: $source_file", $text_color);

  header("Cache-Control: no-store");
  header('Expires: '.gmdate('D, d M Y H:i:s', time()-1000).' GMT');
  header('Content-Type: image/jpeg');
  ImageJpeg($im);
  ImageDestroy($im);

  exit();
}

将页面内容保存为图像文件
