Question

我无法找到丢失的花括号，但我收到此消息"Parse error: syntax error, unexpected $end in /site/public_html/core/functions/users.php on line 75"

以下代码..

<?php

function activate($email, $email_code) {
    $email = mysql_real_escape_string($email);
    $email_code = mysql_real_escape_string($email_code);

    if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1) {
        mysql_query("UPDATE `users` SET `active` = 1 WHERE `email` = '$email'");
        return true;

function user_data($user_id) {
    $data = array();

感谢您的帮助。

Answer 1

您的activate()函数似乎缺少结束括号}。

function activate($email, $email_code) {
  $email = mysql_real_escape_string($email);
  $email_code = mysql_real_escape_string($email_code);

  if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1) {
    mysql_query("UPDATE `users` SET `active` = 1 WHERE `email` = '$email'");
    return true;
  } else {
    return false;
  }

} /* MISSING BRACKET */

function change_password ($user_id, $password) {
  ...

Answer 2

您的第一个function缺少右括号}：

function activate($email, $email_code) {
    $email = mysql_real_escape_string($email);
    $email_code = mysql_real_escape_string($email_code);

    if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1) {
        mysql_query("UPDATE `users` SET `active` = 1 WHERE `email` = '$email'");
        return true;
    } else {
        return false;
    }

此外，缩进有助于更轻松地找到这样的问题（以及与您的大括号匹配的IDE）

Answer 3

您没有关闭第一个功能，所以只需在末尾添加}

function activate($email, $email_code) {
$email = mysql_real_escape_string($email);
$email_code = mysql_real_escape_string($email_code);

if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1) {
mysql_query("UPDATE `users` SET `active` = 1 WHERE `email` = '$email'");
return true;
} else {
return false;
}
}

哦，顺便停止使用常规的PHP mysql_ *函数。从PHP 5.5开始，它们将被弃用，因此请查看mysqli或PDO

Answer 4

我认为第一个功能“激活”没有关闭，在关闭之后添加}。

function activate($email, $email_code) {
    $email = mysql_real_escape_string($email);
    $email_code = mysql_real_escape_string($email_code);

    if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1) {
        mysql_query("UPDATE `users` SET `active` = 1 WHERE `email` = '$email'");
        return true;
    } else {
        return false;
    }
}

Answer 5

你错过了}

应该是

function activate($email, $email_code) {
$email = mysql_real_escape_string($email);
$email_code = mysql_real_escape_string($email_code);

if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1) {
mysql_query("UPDATE `users` SET `active` = 1 WHERE `email` = '$email'");
return true;
} else {
return false;
}
} <---missing bracket here
