Php .ttf文件不工作

我有一个

.ttf

文件要加载到验证码图像中。但是我的

.ttf

就是不起作用。当我包含

.ttf

文件时，图像不会加载并给出错误信息

这是我的验证码：

<?php

session_start();

$md5_hash = md5(rand(0,999));

$captcha = substr($md5_hash, 16, 5);

$_SESSION["captcha"] = $captcha;

$width = 205;
$height = 60;

$image = imagecreate($width, $height);

$white = imagecolorallocate($image, 255, 255, 255);
$black = imagecolorallocate($image, 0, 0, 0);
$grey = imagecolorallocate($image, 204, 204, 204);

imagefill($image, 0, 0, $white);

$font = imageloadfont('Xeron.ttf');
imagestring($image, $font, 70, 20, $captcha, $black);

imagerectangle($image, 0, 0, $width-1, $height-1, $grey);
imageline($image, 0, $height/2, $width, $height/2, $grey);
imageline($image, $width/2, 0, $width/2, $height, $grey);

header("Content-type: image/jpeg");

imagejpeg($image);

imagedestroy($image);

?>

我提供了一个php验证码的示例代码。。。您可以尝试使用您的值、字体、字体颜色等

font-xeron.ttf的位置是什么？它与我的captcha.phpok位于同一位置。你是否尝试使用另一种.ttf字体？尝试将“xeron.ttf”更改为“./xeron.ttf”以明确你想要当前的工作目录。或者指定完整路径。错误日志显示了什么？仅供参考：@DrMJ是的，我尝试使用不同的.ttf文件。但仍然是没有加载。我已经编辑了一些部分…创建captcha.php文件并将其保存在根文件夹中，然后添加index.php的代码。请在我的whatsapp编号9881150272上戳我一下
