只是为了让您提前知道，我是一个相对较新的 php 编码器，正在做一个练习项目，并遇到了这个问题，我花了一个小时的时间重新检查和谷歌搜索，但无法弄清楚是什么原因造成的
error: Parse error: syntax error, unexpected T_STRING, expecting T_FUNCTION in C:\wamp\www\forum\classes\ClassUser.php on line 7
错误：解析错误：语法错误，意外的 T_STRING，在第 7 行的 C:\wamp\www\forum\classes\ClassUser.php 中需要 T_FUNCTION
the segment of the code causing the problem:
导致问题的代码段：
include $_SERVER["DOCUMENT_ROOT"]."forum/classes/general.inc";
Class User{
__construct($u,$p){ //this is line 7
$user=$u;
if(strlen($p)>30|| empty($p) || !preg_match('/[^a-zA-Z0-9]/i',$p)){
$password=0;
}
else{
$password=hash_hmac('md5',$p,KEY);
}
}
oh and since im new to php, incase im doing something which i should not be, please to recommend.. thanks in advance.
哦，因为我是 php 新手，所以我做了一些我不应该做的事情，请推荐.. 提前致谢。
note:ive removed the php tags since they seemed to be messing with the formatting of this post :/
注意：我删除了 php 标签，因为它们似乎弄乱了这篇文章的格式：/
note2: im also getting another notice Notice: Use of undefined constant KEY - assumed 'KEY' in C:\wamp\www\forum\classes\general.inc on line 20
注意2：我还收到另一条通知注意：使用未定义的常量KEY - 在第20行的C:\wamp\www\forum\classes\general.inc中假设为'KEY'
but im assuming thats more of a warning than an error... but just adding incase it has something to do with the error
但我假设那更多的是警告而不是错误......但只是添加柜面它与错误有关

Your __constructneeds to have the word functionin front of it, or better yet public function, in the same way as the other methods in the class (ie validateand insertin your case).
你__construct需要有这个词function在它前面，或者更好public function，以同样的方式在类（即其他的方法validate和insert你的情况）。
ie you need the following:
即您需要以下内容：
public function __construct($u,$p){ //this is line 7
回答by Oscar Broman
Change the line to:
将该行更改为：
public function __construct($u, $p) {
