当我在我的计算机上使用 xampp 测试它时它可以工作，但是当我尝试在我的服务器上运行它时它不起作用。我与 ImageMagick 一起安装了 Tesseract，我所有的 php 文件都设置为 775，但我仍然收到内部服务器错误，我觉得这是因为我缺少依赖项，但老实说我不知道​​哪些依赖项。感谢您的帮助！

问题：我正在想办法解决我的内部服务器错误

Answer 1

PHP 解析错误：语法错误，第 134 行的 test.php 中出现意外的 ')'

你在这一行多了一个)

$average_rank = intval(($highrank + $lowrank) / 2));

应该是

$average_rank = intval(($highrank + $lowrank) / 2);
