</html>我的html和javascript以前在使用硬编码图像名称时似乎工作得很好。我现在使用php从文本文件中输入图像，但现在它似乎不起作用。我发现本地主机当前无法处理此请求错误。
我试着写一个像这样的简单php程序，这似乎很好用。我确信我错过了一些非常愚蠢的事情，但似乎想不出来。请帮助

</html>你不应该得到任何东西：
if (...) {
...
}
fclose($handle);
else { // syntax error: "unexpected else (T_ELSE)"
}和else之间不能有任何代码。它们必须挨着：
if (...) {
...
} else {
...
}
由于这是一个致命的语法错误，因此脚本将失效，并可能在服务器中导致500错误。
