All I am trying to do is: define constraints in yml use this to validate an array Say, a product array: $product['name'] = 'A book'; $product['date'] = '2012-09'; $product['price'] = '21.5'; How to do that? First of all, you need to know that Symfony2 validators are not ready to do that easily. It took me some time and some Symfony2 source reading to get a working solution for your cas
我想要做的是： 在yml中定义约束 用它来验证一个数组 说一个产品阵列： $product['name'] = 'A book'; $product['date'] = '2012-09'; $product['price'] = '21.5'; 怎么做？ 首先，您需要知道Symfony2验证程序尚未准备好轻松完成。 我花了一些时间和一些Symfony2源代码阅读来为你的案例找到一个可行的解决方案，而我的解决方案并不那么自然。 我创建了一个需要验证器，你的数组和你的yaml配置文件的类，这样你就可
[SOLVED] I'm running a PHP script (with some includes) on localhost that keeps crashing before the end. Error reporting is on. Opera, Safari and Firefox return an empty screen. But Chrome returns: Unable to load the webpage because the server sent no data. Error code: ERR_EMPTY_RESPONSE Apache logs returns: [Sun Dec 15 19:29:23 2013] [notice] child pid 34267 exit signal Segmentat
[解决了] 我在本地主机上运行PHP脚本（包含一些包含的脚本），并在结束之前不断崩溃。 报告错误。 Opera，Safari和Firefox返回空白屏幕。 但Chrome返回： 无法加载网页，因为服务器没有发送任何数据。 错误代码：ERR_EMPTY_RESPONSE Apache日志返回： [Sun Dec 15 19:29:23 2013] [注意] child pid 34267退出信号分割故障（11） 当我第一次遇到问题时使用PHP 5.5.6降级到PHP 5.4.21后，问题仍然存在。 问题不在
I'm integrating my software (PHP) with SalesForce, using the SalesForce PHP Toolkit. So far, everything's worked great, but when I started writing the code to call convertLead(), I got a "Segmentation Fault" error. This is the code I'm running: require_once('../salesforce/SforceEnterpriseClient.php'); ini_set('soap.wsdl_cache_enabled', 0); $SForce = new SforceEnterprise
我正在使用SalesForce PHP工具箱将我的软件（PHP）与SalesForce集成。 到目前为止，一切都很好，但是当我开始编写代码来调用convertLead（）时，我得到了一个“Segmentation Fault”错误。 这是我正在运行的代码： require_once('../salesforce/SforceEnterpriseClient.php'); ini_set('soap.wsdl_cache_enabled', 0); $SForce = new SforceEnterpriseClient(); $result = $SForce->createConnection('../salesforce/enter
I'm looking to implement an OpenID identity provider as service for a website of mine. I'm going to integrate it with the existing user services that the app provides, so I'd like to use a library rather than a complete OpenID server application (ie the tools listed on the OpenID Identity Servers section all do too much). This leaves the following libraries listed on the OpenID Lib
我正在寻找一个OpenID身份提供者作为我的网站的服务。 我将把它与应用程序提供的现有用户服务集成在一起，所以我想使用库而不是完整的OpenID服务器应用程序（即OpenID Identity Servers部分列出的工具都做得太多）。 这留下了OpenID Libraries页面上列出的以下库（那些能够充当身份提供者的人;其他人被忽略，因为他们无法做我想要的东西）。 不幸的是，每个人都有一些问题，我很乐意提供有关我应该去哪些方面的建议。 PHP
In Emacs, I am writing a PHP file that mixes both PHP and non-PHP code, which will be in C++ mode. I would like the PHP code to be highlighted with a link-pink background in order to make it stand out visually. To do this, I use the font-lock setting: (make-face 'font-lock-special-macro-face) (set-face-background 'font-lock-special-macro-face "pink") (defun add-custom-keyw() "adds a few spe
在Emacs中，我正在编写一个混合PHP和非PHP代码的PHP文件，这些代码将采用C ++模式。 我希望PHP代码能够通过链接粉红色背景突出显示，以使其在视觉上突出。 为此，我使用字体锁定设置： (make-face 'font-lock-special-macro-face) (set-face-background 'font-lock-special-macro-face "pink") (defun add-custom-keyw() "adds a few special keywords for c and c++ modes" ; (font-lock-add-keywords nil '(
Let's call this table CATEGORIES: +---------+------- | id | name | +-----+----------| | 1 | CATEG 1 | | 2 | CATEG 2 | | 3 | CATEG 3 | | 4 | CATEG 4 | And this is Items: +----+-------------+---------------+-------- | id | name | categoryid | price |
我们称这个表为CATEGORIES： +---------+------- | id | name | +-----+----------| | 1 | CATEG 1 | | 2 | CATEG 2 | | 3 | CATEG 3 | | 4 | CATEG 4 | And this is Items: +----+-------------+---------------+-------- | id | name | categoryid | price | +---
I have 5 tables in my database. [Items] - id, name, etc... [Categories] - id, name [Tags] - id, name 2 Joining tables [Items_Categories] - item_id, category_id [Items_Tags] - item_id, tag_id I simply need to know the best performing query (using JOINS as necessary) to pull 1 or more items from the DB WITH all of it's information, including the Categories AND Tags, given the item
我的数据库中有5个表格。 [物品] - 身份证，名称等... [类别] - 编号，名称 [标签] - ID，名称 2加入表格 [Items_Categories] - item_id，category_id [Items_Tags] - item_id，tag_id 我只需要知道性能最好的查询（根据需要使用JOINS），从数据库中提取1个或多个项目，并提供item_id = $ id在内的所有信息，包括类别和标签。 到目前为止，我有以下工作，但在25 - 50个查询中，它很慢（有没有人有更好
I have a table which contains the scores by user, for a game: UserID (Integer) MatchId (Integer) Score (Double) I'd like to getter sum each user's "points above average" (PAA) - the amount by which a user's score was above or below the average. So you'd need to calculate the average of 'Score' for each 'MatchId', then for each row in the table calcula
我有一个表格，其中包含用户对游戏的评分： UserID (Integer) MatchId (Integer) Score (Double) 我想让每位用户的“分数高于平均水平”（PAA） - 用户得分高于或低于平均水平的总和。 因此，您需要为每个“MatchId”计算“Score”的平均值，然后对表中的每一行计算“Score”与匹配平均值的差异。 然后按用户总和该PAA值。 是否有可能通过MySQL查询做到这一点？ 或者我需要PHP吗？ 如果可以通过查询完成，该查询将是什么样子？
I was researching about mysqli prepared statements and i have 2 questions about it. As i was reading, i figure out that the order of execution of a prepared statement looks something like the following: $sql = 'SELECT image_id, filename, caption FROM images WHERE image_id = ?'; // connect to the database $conn = .... $stmt = $conn->stmt_init(); $stmt->prepare($sql); $stmt->bind_pa
我正在研究关于mysqli准备的陈述，我有两个关于它的问题。 在我阅读时，我发现准备好的声明的执行顺序如下所示： $sql = 'SELECT image_id, filename, caption FROM images WHERE image_id = ?'; // connect to the database $conn = .... $stmt = $conn->stmt_init(); $stmt->prepare($sql); $stmt->bind_param('i', $id); $stmt->execute(); $stmt->bind_result($image_id, $filename, $caption); //
This is more of a conceptual question than a specific code question. Right I am developing a mobile app and am trying to figure out the best way to track data. What I mean by this is: For every user that signs up I want them to have custom analytics for their accounts based off of the users interactions with them. For example if it was Facebook: We have 3 user profiles (a,b,c) I need to kn
这是一个概念性问题，而不是特定的代码问题。 对，我正在开发一款移动应用程序，并试图找出跟踪数据的最佳方式。 我的意思是： 对于每个注册用户，我都希望他们根据用户与他们的交互情况为他们的帐户进行自定义分析。 例如，如果它是Facebook：我们有3个用户配置文件（a，b，c）每次用户访问配置文件A（基本计数）时我需要知道每次用户访问配置文件B时需要知道的内容（基本计数）I每次用户访问配置文件C需要知道（基本计
