基本上我是用PHP和HTML创建基于事件的预订系统，代码是粗体

我一直在第320行收到语法错误，说文件意外结束，任何人都可以告诉我修复错误的方法和位置。enter code here

尽管代码的格式非常糟糕，但快速浏览一下后会告诉我它以?>}结束，应该是}?>。

你的错误就在这个区块的某个地方
if ($line[idx] != $idx)
{
$errtext = "Conflict: ".substr($line[begtime],0,5)."-" + substr($line[endtime],0,5).":".$line[subj];
return($errtext);
} } // Check to make sure ending time doesnt run into another appt $query = "SELECT idx,begtime,endtime,subj FROM appts
WHERE date = \"$date\" AND ".
"\"".$endtime."\" >= begtime AND \"".$endtime."\" <=
endtime"; $result = mysql_query($query,$link)
or die("Query Error!<p>Query: $query<p>Error:
".mysql_error()); // If overlap (conflict) found, display error while ($line =
mysql_fetch_array($result,MYSQL_ASSOC)) {
if ($line[idx] != $idx) {
你有太多“在那里打破了代码流，这在网站上启用了代码突出显示时是显而易见的，因为它开始用简单的红色填充php，通常用于字符串。
我建议你开始计算你的“并检查任何内联是否已正确转义\ _等。
更具体地说是这个位
WHERE date = \"$date\" AND ".
"\"".$endtime."\"

此处or die("Query Error!<p>Query: $query<p>Error: " mysql_error());也是错误。
