Question

我正在使用横幅生成器。如果我访问banner.php?id=<ID>，所有代码都可以正常运行。我正在研究localhost所以，我知道，如果我想看到我创建的这个图像，我必须写：

<img src="http://localhost/banner.php?id=<ID>" />

如果我访问直接链接，我只能看到图像。如果我将其添加到<img>标记中，为什么我看不到它？我以为是因为我使用cURL来获取一些变量，但没有。

Answer 1

这部分错了

<img src="http://localhost/banner.php?id=<ID>" />

应该是

<img src="http://localhost/path to your image" />

如果你已经完成了，请点击某个页面，

那么它应该是

<a href="http://localhost/banner.php?id=<ID>">
    <img src="http://localhost/path to your image" />
</a>

Answer 2

你能告诉我们你的代码吗？你使用哪个图形库？我在本地计算机上使用GD2没有任何问题。

E.g。

<?php

header('Content-type: image/png');
$img = imagecreate(256, 256);
$background = imagecolorallocate($img, 255, 255, 0);
$color = imagecolorallocate($img, $_GET['red'], $_GET['blue'], $_GET['green']);
imagearc($img, 128, 128, 64, 64, 0, 0, $color);
imagepng($img);

?>

然后在HTML文件中：

<img src="img.php?red=255&blue=0&green=0" />

为我工作......

Answer 3

当我将文件名“banner.php”更改为其他名称时，例如：'counter.php'，... 相同的代码工作正常。我不知道文件名的原因是name =“banner”产生了这个错误

使用PHP创建的图像不会显示
