我正在使用此 php 代码制作一个 facebook 应用程序。我将字体 Arial.ttf 上传到我网站的根目录。但我仍然显示错误 - Warning: imagettftext() [function.imagettftext]: Could not find/open font in/home/a2424901/public_html/index.php on line 35。我尝试改变案例，但我没有为我工作。我在这段代码中哪里出错了？

最佳答案

From the docs

Depending on which version of the GD library PHP is using, when fontfile does not begin with a leading / then .ttf will be appended to the filename and the library will attempt to search for that filename along a library-defined font path.

这似乎暗示字体文件应该是绝对路径，如果不是，函数将在其末尾附加另一个 .ttf。

指定字体文件的完整路径。

$font = "/home/a2424901/public_html/Arial.ttf";

或者省略 .ttf 并使用 GDFONTPATH。 The documentation建议如下:

In many cases where a font resides in the same directory as the script using it the following trick will alleviate any include problems.

putenv('GDFONTPATH=' . realpath('.'));
$font = "Arial";
