I want to display youtube video in place of the "youtubeURL" or the direct embed code of youtube if the text data contains any of the above way. example: If user enters following text into text area : "Here is video by embed code: < iframe width="420" height="315" src="https://www.youtube.co

Php动态嵌入YouTube视频

我的页面接受文本区域中的任何文本,没有字符数限制。 如果文本数据包含以上任何一种方式,我想要显示youtube视频以代替“youtubeURL”或youtube的直接嵌入代码。 例如:如果用户在文本区域输入以下文本: “这里是嵌入代码的视频:<iframe width =”420“height =”315“src =”https://www.youtube.com/embed/7M-jsjLB20Y“frameborder =”0“allowfullscreen> </ iframe>这里是网址的视频:https://www.youtube.com/wa

Retrieve messages from RabbitMQ queue(s)

I'm looking to implement RabbitMQ into my PHP application, and am using the php-amqp extension. My only question is this, how do I easily query to return the contents of the queue in PHP? php-amqp seems to not enable me to do this. If I am going wrong, please help me out here :) James, could you please ask this question on rabbitmq-discuss? Your question touches on what it means to 

从RabbitMQ队列中检索消息

我期待在我的PHP应用程序中实现RabbitMQ,并使用php-amqp扩展。 我唯一的问题是,我如何轻松地查询返回PHP中队列的内容? php-amqp似乎不能让我这样做。 如果我错了,请帮我在这里:) 詹姆斯,你可以在rabbitmq-discussion上提出这个问题吗? 你的问题涉及到“查询”队列以获取消息的含义。 在RabbitMQ中,您使用来自队列的消息,并使用队列绑定执行过滤。 看看这个介绍 - http://blogs.digitar.com/jjww/2009/01/rabbits

SELECT string AS column

I have the following which works fine as a standard MySQL query: SELECT 'page' AS result_type,... However, I need to create this query using active record in the codeigniter framework. I tried this: $this->db->select(''page' AS result_type'); But that returns an error saying Unknown column ''page'' in 'field list' I've tried various other similar approach

SELECT字符串AS列

我有以下的作为一个标准的MySQL查询工作正常: SELECT 'page' AS result_type,... 但是,我需要使用codeigniter框架中的活动记录创建此查询。 我试过这个: $this->db->select(''page' AS result_type'); 但是Unknown column ''page'' in 'field list'中返回一个错误,说明Unknown column ''page'' in 'field list' 我尝试了各种其他类似的方法,但都失败了。

CodeIgniter Active Record: Debugging without running SQL

I'm fairly new to Code Igniter, and I'm using Active Record for all the queries in a new project. Is there a way to output the SQL statement without actually running it. The function i've created has quite a few statements in it, selects, deletes and updates, and I want to make sure they are correct before running them in a test environment as they have a lot of Ifs and cases arou

CodeIgniter Active Record:在不运行SQL的情况下进行调试

我对Code Igniter相当陌生,而且我正在使用Active Record来处理新项目中的所有查询。 有没有一种方法可以输出SQL语句而不需要实际运行它。 我创建的函数在其中有很多语句,选择,删除和更新,并且在测试环境中运行它们之前我想确保它们是正确的,因为它们有很多Ifs和它们周围的案例来构建查询。 所以简而言之,我只是想让它回应声明,但不能运行它。 提前致谢! :) 查看用户指南的数据库查询助手部分列出的insert_str

Codeigniter active record sql error

I am using the get_where() function in codeigniter, and I am getting mysql errors, dependent on what I set the limit and offset too, for example this code, $this->db->get_where('em_user', $whereArr, 30, 0)->num_rows() returns a mysql error that looks like this, Error Number: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version f

Codeigniter主动记录sql错误

我在codeigniter中使用了get_where()函数,并且我得到了mysql错误,这取决于我设置的极限和偏移量,例如这个代码, $this->db->get_where('em_user', $whereArr, 30, 0)->num_rows() 返回一个看起来像这样的mysql错误, 错误号码:1064 你的SQL语法有错误; 检查与您的MySQL服务器版本相对应的手册,以便在第2行'WHERE email ='your@emailaddress.com'AND password ='letmein'LIMIT 1'附

Active Record implementation of this SQL?

I am using CodeIgniter. My database is MySQL 5. The SQL statement below works fine, but I am thinking it would not really be compatible with MSSQL, PG, et al. I am wondering if it's possible to implement the statement using the Active Record class in CI, hence making it completely cross database ? I think the "GROUP_CONCAT" is where I'll fall down... EDIT - Found on the Co

此SQL的Active Record实现?

我正在使用CodeIgniter。 我的数据库是MySQL 5.下面的SQL语句工作正常,但我认为它不会真正与MSSQL,PG等人兼容。 我想知道是否可以使用CI中的Active Record类来实现语句,从而使它完全跨越数据库? 我认为“GROUP_CONCAT”是我会跌倒的地方...... 编辑 - 在CodeIgniter板上找到 “然而,应该指出的是,CONCAT是特定于数据库的,它实际上并不是活动记录库的一部分,尽管我确信大部分数据库引擎都支持它。” 我可能不得不重

Master / Slave switch in the Zend Framework application layer

I am writing an application which requires the Master/Slave switch to happen inside the application layer. As it is right now, I instantiate a Zend_Db_Table object on creation of the mapper, and then setDefaultAdapter to the slave. Now inside of the base mapper classe, I have the following method: public function useWriteAdapter() { if(Zend_Db_Table_Abstract::getDefaultAdapter() != $this-

Zend Framework应用程序层中的主/从切换

我正在编写一个应用程序,要求在应用程序层内发生主/从切换。 就像现在一样,我在创建映射器时实例化一个Zend_Db_Table对象,然后将setDefaultAdapter设置为从器件。 现在在基本映射器类中,我有以下方法: public function useWriteAdapter() { if(Zend_Db_Table_Abstract::getDefaultAdapter() != $this->_writeDb) { Zend_Db_Table_Abstract::setDefaultAdapter($this->_writeDb); $this-&g

Does output buffering in PHP require more resources?

When performance is important including server memory,I am curious if using output buffering like ob_start(); in PHP has ANY performance hits over not using it? Does it use more memory or anything to use it? In my situation on a high traffic site where I need all the memory I can for memcache and APC and all the other server activities I am just curious if I should use it or not, the only rea

PHP中的输出缓冲需要更多资源吗?

当性能很重要,包括服务器内存时,我很好奇如果使用输出缓冲像ob_start(); 在PHP有任何性能命中不使用它? 它使用更多的内存或任何东西来使用它? 在我需要所有内存的高流量网站上,我可以使用memcache和APC以及所有其他服务器活动,但我只是好奇我是否应该使用它,它适用于我的唯一真正原因是重定向页面,发送标题我应该说已经发送标题后,我的网站有标题,正文,页脚文件设置,所以有时我需要重定向取决于什么是正文文件

Source Forum with API

有没有人对基于PHP,Python或J2EE的网络论坛提出建议,该论坛有一个用于编程创建用户和论坛主题的良好API? phpBB would be the first that comes to mind as open-source, simply because it's free. In reality almost all forum platforms have some sort of 'api' in that you can do whatever you need programatically, it just may not be as simple as 'add_user(bob)'. A few lines of code and

来源论坛与API

有没有人对基于PHP,Python或J2EE的网络论坛提出建议,该论坛有一个用于编程创建用户和论坛主题的良好API? phpBB将是第一个想到开源的,因为它是免费的。 实际上几乎所有的论坛平台都有某种'api',你可以通过编程方式做任何你想做的事情,它可能不像'add_user(bob)'那么简单。 几行代码和一个SQL查询或两个,你通常可以实现你需要的一切。 出于个人喜好,我会推荐vBulletin,但它确实有收费。 这样做的

Is there a good alternative to PHP's SOAP extension?

I have a project which relies heavily on PHP's SOAP extension. It's great, and works wonderfully. However, I have to deploy a version of the software on a server that does NOT have the extension (it is PHP5 though). At this time, changing hosts is not an option; and it looks like installing the extension is also not an option. Is there a pure PHP implementation of a SOAP client lib

PHP的SOAP扩展有没有一个好的选择?

我有一个项目严重依赖PHP的SOAP扩展。 这很棒,而且非常出色。 但是,我必须在没有扩展名的服务器上部署软件版本(尽管它是PHP5)。 此时,更换主机不是一种选择; 它看起来像安装扩展也不是一个选项。 是否有一个纯粹的PHP实现的SOAP客户端库,我可以使用它的位置? 我不期望有完美的替代品 - 我完全准备好修改一堆代码 - 但我可以使用的东西。 的NuSOAP: http://sourceforge.net/projects/nusoap/
