好吧,我正在使用这个PHP代码制作一个facebook应用程序Arial.ttf.我将字体上传到我的网站的根目录.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.我在这段代码中出错的地方？

Answer 1

来自文档

根据PHP使用的GD库版本,当fontfile不以前导/开头时,然后.ttf将附加到文件名,库将尝试沿库定义的字体路径搜索该文件名.

这似乎意味着fontfile应该是一个绝对路径,如果不是,该函数会将另一个附加.ttf到它的末尾.

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. 文档建议如下:

在许多情况下,字体与使用它的脚本位于同一目录中,以下技巧将缓解任何包含问题.

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

Answer 2

添加到user2724960的答案; 更改FontName __DIR__ . '/graph/fonts/someFont.ttf'为我做了.

全线:

$myPicture->setFontProperties(array("FontName"=>__DIR__ .  '/graph/fonts/someFont.ttf',"FontSize"=>14));

不要忘记将" someFont " 替换为您的字体文件名称(默认值:"Forgotte")

Answer 3

我也在使用 XAMPP，显然 XAMPP 只支持字体的完整目录路径。此代码可以在 Windows (XAMPP) 和我们的提供商 Linux 服务器上运行：

$dir= dirname(realpath(__FILE__));
$sep=DIRECTORY_SEPARATOR;   
$font =$dir.$sep.'arial.ttf';
imagettftext($thumb, $size, 0, $y_pos, $size, $textcolor, $font, $txt);

（假设你的字体文件与你的php文件在同一目录中）

Answer 4

我的解决方案（对我有用）：

realpath('here/is/right/path/to/font.ttf');
