My code produces the following error when trying to connect to a site, and I'm trying to figure out how to resolve it: Connection error: SQLSTATE[HY000] [2002] No connection could be made because //the target machine actively refused it.

我的代码在尝试连接到一个站点时产生以下错误，我试图找出如何解决它： 连接错误：SQLSTATE [HY000] [2002] 由于目标机器主动拒绝它，因此无法建立连接。 （ ！ ） 致命错误： 调用第53行的C： wamp64 www Allaboutphp Class.User.php中的null成员函数prepare（）调用堆栈 Time Memory Function Location 1 0.0012 249224 {main}( ) ...Index.php:0 2 2.0062 297264 USER->login( ) ...Index.php:16 //dbcon
I am working on a small Project with Unity3D and i want to post on mySQL Database players Name and Score. The php Script takes Values from some c#. I can't get it to have per Name only one Row on Database. The Script does Post now but only like this Name Score mico 12 maku 20 mico 18 mico 100 What I really want is just mico 24 maku 20 try { $dbh = new PDO('mysql:host=&#
我正在使用Unity3D开发一个小型项目，并且希望在mySQL数据库播放器名称和分数上发布。 PHP脚本从一些C＃中获取值。 我不能让它具有每个名称只有一个数据库上的行。 该脚本现在发布，但只是喜欢这个名称得分 mico 12 maku 20 mico 18 mico 100 我真正想要的只是 mico 24 maku 20 尝试{$ dbh = new PDO（'mysql：host ='。$ hostname。'; dbname ='。$ database，$ username，$ password）; }
I have searched every single answer regarding this and none seem to fully answer what's going on. Currently I am getting the error in the title when trying to prepare a statement with pdo. I have tried: Using a constructor instead Using non-static Using $this when I had a constructor Catching PDO exceptions, none seem to be thrown Here is main.php class db { public static $d
我已经搜索了关于这个的每一个答案，而且似乎没有人完全回答发生了什么。 目前，我在尝试使用pdo准备语句时遇到标题错误。 我努力了： 改为使用构造函数 使用非静态 当我有一个构造函数时使用$ this 捕捉PDO异常，似乎没有人抛出 这里是main.php class db { public static $db; public static $db2; public static function start() { $host = "localhost"; $dbname = "dbname";
Ok, so I was following this tutorial, which who knows, may or may not be accurate. when I choose submit, I get a 403 error. and a screen with half the PHP code. from where I am sitting it is a syntax error, but for the life of me, I cannot figure out why. I have run it through notepad++ phpdesigner and a few online checkers. most of them say it is fine, however the lint check shows an synta
好的，所以我按照这个教程，谁知道，可能会或可能不准确。 当我选择提交时，我得到一个403错误。 和一半的PHP代码的屏幕。 从我坐的地方来看，这是一个语法错误，但在我的生活中，我无法弄清楚为什么。 我已经通过记事本++ phpdesigner和一些在线检查器来运行它。 他们中的大多数都表示没问题，但是lint检查显示出现了一个语法错误，除此之外，我被困住了。 起初我以为403错误是基于权限的，但是我回到了另一个项目，并
Code below inserts single record twice. Note: there is no other code in a script besides what you see below (except for DB_HOST, DB_NAME etc. constants). code: $dbh = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB_NAME, DB_USER, DB_PASSWORD, array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES 'UTF8'')); $array = array( '2' => '13' ); $sql = "INSERT INTO htdopen.oc_product_option (p
下面的代码将插入单个记录两次。 注意： 除了您在下面看到的脚本外，脚本中没有其他代码（DB_HOST，DB_NAME等常量除外）。 码： $dbh = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB_NAME, DB_USER, DB_PASSWORD, array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES 'UTF8'')); $array = array( '2' => '13' ); $sql = "INSERT INTO htdopen.oc_product_option (product_id, option_id, required)
I have an INSERT wrapped in a try/catch, but a missing table is not getting caught and PHP is erroring out at '$dbh->prepare'. I've set the 'PDO::ATTR_ERRMODE' and the value echoed to the browser just before the '$dbh->prepare' is 2. If the table exists, the INSERT works as I expected. I only discovered there was an issue while testing when I purposely droppe
我有一个INSERT封装在try / catch中，但是缺少的表不会被捕获，PHP会在'$ dbh-> prepare'中出错。 在'$ dbh-> prepare'为2之前，我已经设置了'PDO :: ATTR_ERRMODE'，并将值回显给浏览器。 如果该表存在，INSERT按我的预期工作。 当我故意丢弃表格并运行代码时，我才发现有问题。 我忽视了什么？ 提前致谢 PHP致命错误：在C： etc httpd htdocs sqlite_data gather.php中有'
I have a form that allows a user to fill in several aspects and then choose a file to upload. When the form is submitted, I want write some code that saves the file to a dropbox account and gets access to a direct download link and places this in a database I am hosting. If anyone has done this, is there a specific section of the API to look at? Or any examples? I can't seem to find th
我有一个表单，允许用户填写几个方面，然后选择要上传的文件。 当提交表单时，我想写一些代码将文件保存到Dropbox帐户，并获得直接下载链接并将其放入我所托管的数据库中。 如果有人这样做了，是否有API的特定部分来看？ 或者任何例子？ 我似乎无法在API中找到它。 谢谢。 从我在API中看到的，可以做到这一点。 您需要下载Dropbox Core API。 在zip文件中，您将找到一个示例文件夹，其中包含用于验证，上传，下载，
Doctrine is generating migration in symfony and nothing changes afer running the migration so during next diff it is the same. How to make Doctrine not generate this migration? Running the alter table command manually does not remove column collation. bin/console doctrine:migration:diff up $this->addSql('ALTER TABLE session CHANGE sess_id sess_id VARCHAR(128) NOT NULL'); down $this->
Docfine正在symfony中生成迁移，并且在迁移迁移时没有任何更改，因此在下次比较时它是相同的。 如何使Doctrine不会产生这种迁移？ 手动运行alter table命令不会删除列归类。 bin/console doctrine:migration:diff 向上 $this->addSql('ALTER TABLE session CHANGE sess_id sess_id VARCHAR(128) NOT NULL'); 下 $this->addSql('ALTER TABLE session CHANGE sess_id sess_id VARCHAR(128) NOT NULL COLLATE utf8_unic
I set all character set as "utf8" in pages, I set all collation (also fields collation) as utf8_general_ci in database, and I add this code in connect.php mysql_set_charset('utf8',$connect); mysql_query("SET NAMES 'utf8'"); Although everything is utf, when i run this query: "SELECT * FROM titles WHERE title='toruń'" Result: it returns " toruń " and &quo
我将所有字符集都设置为“utf8”，我将所有排序规则（字段排序规则）设置为数据库中的utf8_general_ci ，然后将此代码添加到connect.php mysql_set_charset('utf8',$connect); mysql_query("SET NAMES 'utf8'"); 虽然一切都是utf，但当我运行这个查询时： "SELECT * FROM titles WHERE title='toruń'" 结果：返回“ toruń ”和“ torun ”，它的不同的话。 所以你怎么看？ 问题是什么？ 谢谢！ 编辑：
A site I've built uses the Advanced Custom Fields plugin, and everything works well on localhost on my own web host. Unfortunately, when I moved the site to the hosting that the client purchased (GoDaddy shared hosting), the JavaScript and CSS files for the Advanced Custom Fields plugin are not loading properly.
