This question already has an answer here: How to fix “Headers already sent” error in PHP 11 answers Turned out that it was the line ob_start("ob_gzhandler"); that caused the warning. This has been reported and fixed in 2001, it seems, but for some reason it keeps coming back. It might be a lot of things, but as the others said, it's often just a space lying around somewhere that gets
这个问题在这里已经有了答案： 如何解决PHP 11中的“Headers already sent”错误 原来是这条线 ob_start("ob_gzhandler"); 导致警告。 这在2001年已经被报道和修复，似乎，但由于某种原因它不断回来。 它可能是很多东西，但正如其他人所说的那样，它通常只是一个位于输出位置的空间，然后发送一个通常很好的header()命令，而不是在开始发送内容之后（可能只是在这种情况下是一个空间）。 使用ob_start()可以通过缓冲来
I keep reading it is poor practice to use the PHP close tag ?> at the end of the file. The header problem seems irrelevant in the following context (and this is the only good argument so far): Modern versions of PHP set the output_buffering flag in php.ini If output buffering is enabled, you can set HTTP headers and cookies after outputting html because returned code is not sent to the brow
我一直在读这是不良的做法使用PHP结束标记?>在文件的结尾。 标题问题在以下情况下似乎不相关（迄今为止，这是唯一有效的论据）： 现代版本的PHP在php.ini中设置output_buffering标志如果启用了输出缓冲，则可以在输出html之后设置HTTP标头和cookie，因为返回的代码不会立即发送到浏览器。 每本优秀的练习册和wiki都以这条“规则”开始，但没有人提供很好的理由。 是否有另一个很好的理由跳过结尾的PHP标签？ 虽然我不记
Is there a way to fix the characters that display improperly after running this html markup through phpquery::newDocument? There are slated double quotes around -Classics with modern Woman- in the original document that end up displaying improperly after creating the new doc with phpquery. //Original document is UTF-8 encoded $raw_html = '<html><head><meta http-equiv="Content

In my project, i have an ajax.php which is handling all AJAX POST requests. It gets the command, verifies all the required arguments exist and pass it off to the relevant class. I've seen the new '??' operator and have started verifying the POST arguments like this, $name = $_POST['name'] ?? die('{"result":0, "data":"name not provided"}'); $state = $_POST['state'] ?? die('{"resul
在我的项目中，我有一个处理所有AJAX POST请求的ajax.php。 它获取命令，验证所有需要的参数并将其传递给相关类。 我见过新的'??' 运算符，并开始验证这样的POST参数， $name = $_POST['name'] ?? die('{"result":0, "data":"name not provided"}'); $state = $_POST['state'] ?? die('{"result":0, "data":"state not provided"}'); 我认为这比看起来更好， $name = isset($_POST['blah']) ? $_POST['blah'] : di
I want to build an audio transcribing application for my organization which will at the end look like this from the front end This will be a very simple speech to text feature. I came across CMUSphinx which look promising, but before spending time on this library, I wanted to know if there are any other libraries that might suit my needs better? Do you have experience with any audio transcr
我想为我的组织制作一个音频录制应用程序，最终会在前端看起来像这样 这将是一个非常简单的文字功能演讲。 我遇到了看起来很有前途的CMUSphinx ，但在花时间在这个图书馆之前， 我想知道是否有其他图书馆可以更好地满足我的需求？ 您是否有任何音频录制库的经验，可以在这里完成这项工作？ PS：我正在标记这个问题的PHP，但我打开这里的任何建议。 微软SAPI（语音API）是完美的。 我过去使用它，它很好地工作
I need to order data by two columns (when the rows have different values for column number 1, order by it; otherwise, order by column number 2) I'm using a QueryBuilder to create the query. If I call the orderBy method a second time, it replaces any previously specified orderings. I can pass two columns as the first parameter: ->orderBy('r.firstColumn, r.secondColumn', 'DESC'); But
我需要按两列对数据进行排序（当列号为1的行具有不同值时，按顺序排列;否则，按列号排序） 我正在使用QueryBuilder来创建查询。 如果我第二次调用orderBy方法，它会替换之前指定的任何顺序。 我可以传递两列作为第一个参数： ->orderBy('r.firstColumn, r.secondColumn', 'DESC'); 但是我无法为第二个参数传递两个排序方向，所以当我执行此查询时，第一列按升序方向排序，第二列按降序排列。 我想为他们两个使用降序
I have the following function that instantiates an object and runs its method. I want to return $to_return but the problem is that $to_return does not change even when the function is using 'use' keyword. Here is the function: function some_function($arg){ $to_return = false; $object = new Object; $to_return = $object->METHOD(function($callback) use ($to_return){
我有以下函数实例化对象并运行其方法。 我想返回$to_return但问题是即使函数使用'use'关键字， $to_return也不会改变。 这是功能： function some_function($arg){ $to_return = false; $object = new Object; $to_return = $object->METHOD(function($callback) use ($to_return){ $to_return = $some_var; }); $to_return = $object->runMETHOD("some_arg"); return $

What messaging platform would be the best choice for asynchronous message queuing (publish, consume) between PHP and Java apps? I have looked at RabbitMQ, ActiveMQ, OpenAMQ, Tibco Rendezvous, and Websphere MQ. Persistence is required. I love the idea of AMQP and using an open protocol, but I've heard of stability issues with RabbitMQ, which seems to be the leading AMQP implementation. Me
什么消息传递平台将是PHP和Java应用程序之间的异步消息队列（发布，消费）的最佳选择？ 我看过RabbitMQ，ActiveMQ，OpenAMQ，Tibco Rendezvous和Websphere MQ。 持久性是必需的。 我喜欢AMQP的想法并使用开放协议，但我听说过RabbitMQ的稳定性问题，这似乎是AMQP的主要实现。 消息传递的负载不会完全符合“Twitter风格”的规模，但会是相当高的数量，并且需要非常高的可用性。 官方支持的PHP API肯定会获得积分。 Java和PH
