What is the best and reliable way to detect mime type of a file in php? The following code which is suggested by many people failed to detect docx file mime type: $finfo = new finfo(FILEINFO_MIME_TYPE); $mime = $finfo->file($_FILES['file']['tmp_name']); echo $mime; exit; This is printing application/zip but it is supposed to be application/vnd.openxmlformats-officedocument.wordproce
在php中检测MIME类型的文件的最好和可靠的方法是什么？ 以下由许多人建议的代码未能检测到docx文件MIME类型： $finfo = new finfo(FILEINFO_MIME_TYPE); $mime = $finfo->file($_FILES['file']['tmp_name']); echo $mime; exit; 这是打印应用程序/ zip，但它应该是 应用/ vnd.openxmlformats-officedocument.wordprocessingml.document 基于这个我已经将它移植到PHP： function getMicrosoftOfficeMimeInfo($fil
I need determine what is type of uploaded file When upload .xlsx file, this code: echo $_FILES['uploaded_file']['type']."<br>"; echo mime_content_type($_FILES['uploaded_file']['tmp_name']); returns: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet application/vnd.ms-excel As I know (from here PHP xls, xlsx, ppt, pptx headers), application/vnd.ms-excel is not .xlsx
我需要确定上传文件的类型 上传.xlsx文件时，此代码： echo $_FILES['uploaded_file']['type']."<br>"; echo mime_content_type($_FILES['uploaded_file']['tmp_name']); 收益： application/vnd.openxmlformats-officedocument.spreadsheetml.sheet application/vnd.ms-excel 据我所知（从这里PHP xls，xlsx，ppt，pptx头文件）， application/vnd.ms-excel不是.xlsx ，而是.xls文件MIME类型。 那么，为什么
I have long used the mysql_query() to do my stuff but now I am shifting to prepared statements for two reasons: performance and no sql injection possibility This is how I am using it: function add_new_user($e_mail1,$username,$pass) { require_once "db.php"; $stmt = $mysqli->prepare("INSERT INTO un_users VALUES ('',?, ?,0,0,?,0)"); $stmt->bind_param('sss', $e_mail1, $username,$p
我很久以前用mysql_query（）来做我的东西，但现在我转向准备语句有两个原因： 性能和没有SQL注入的可能性 这就是我使用它的方式： function add_new_user($e_mail1,$username,$pass) { require_once "db.php"; $stmt = $mysqli->prepare("INSERT INTO un_users VALUES ('',?, ?,0,0,?,0)"); $stmt->bind_param('sss', $e_mail1, $username,$pass); $stmt->execute(); $stmt->close(); }
Looking for Hello World Type Example of Web Sockets Implementation: Here is Socket Create reference from php.net but this looks more low level than Web Sockets. I want to use this Web Sockets as shown here on caniuse.com which is now implemented in all new major browsers. A Google search turned up this Nets.TutsPlus site in which I can use the JavaScript example code...but I need to know ho
寻找Hello World类型Web Sockets实现示例： 这里是来自php.net的Socket创建引用，但这看起来比Web Sockets更低。 我想在caniuse.com上使用这个Web套接字，它现在已在所有新的主流浏览器中实现。 谷歌搜索发现了这个Nets.TutsPlus网站，我可以在其中使用JavaScript示例代码......但我需要知道如何在PHP中实现服务器端，而不是Java，Ruby或Node.js，如示例中所示。 PHP套接字创建相关？ PHP本身支持Web套接字吗？ 我想只
Right now I am using active records to access the database. However, an additional feature requires me to use standard SQL query. Is it possible to use both active records and standard sql query in the same query? Eg: $this->db->select(...) ->from(...) -> ..... ->query(WHERE CASE ..........); In the standard SQL query, I want to use a WHERE clause wi
现在我正在使用活动记录来访问数据库。 但是，额外的功能需要我使用标准的SQL查询。 是否有可能在同一个查询中同时使用活动记录和标准sql查询？ 例如： $this->db->select(...) ->from(...) -> ..... ->query(WHERE CASE ..........); 在标准SQL查询中，我想在CASE中使用WHERE子句。 这可能没有重写标准SQL中的整个查询？ 活动记录查询非常复杂 据我所知，你不能像你正在做
Is there any function / global variable in PHP that returns the current state of the script (something like runnning, terminating)? Or is the only way to set this state by making use of register_shutdown_function() ? That function looks inflexible to me as an already registered shutdown functions can be overriden with it. And the shutdown function gets executed when a user aborts the connect
PHP中是否有任何函数/全局变量返回脚本的当前状态（如runnning，terminating）？ 或者是通过使用register_shutdown_function()来设置此状态的唯一方法？ 该功能对我来说看起来不灵活，因为已经注册的关闭功能可以被重写。 关机功能在用户放弃连接时执行，这不是我正在寻找的内容，我不想介绍太多限制。 有没有其他的register_shutdown_function()可用？ 否则，如何处理该功能的缺点？ UPDATE 只是为了澄清：我不是在
I recently was seeking a way to properly determine protocol, under which url request was supplied to the server. I watched through parse_url() and though $_SERVER superglobal variable, and found this: <?php header('Content-Type: text/plain'); print_r($_SERVER); ?> Output: [REQUEST_SCHEME] => http However, I was unable to find it on php.net or Google. Though, I was able to find
最近我正在寻求一种方法来正确确定协议，在这个协议下url请求被提供给服务器。 我通过parse_url()和$_SERVER超全局变量观察，发现： <?php header('Content-Type: text/plain'); print_r($_SERVER); ?> 输出： [REQUEST_SCHEME] => http 但是，我无法在php.net或Google上找到它。 虽然，我能够找到这个问题。 问题1：如果没有记录$_SERVER['REQUEST_SCHEME'] ，那么它可能是不可靠的，或者它可以被
你什么时候考虑使用一个，为什么？ The HTTP_HOST is obtained from the HTTP request header and this is what the client actually used as "target host" of the request. The SERVER_NAME is defined in server config. Which one to use depends on what you need it for. You should now however realize that the one is a client-controlled value which may thus not be reliable for use in business logi
你什么时候考虑使用一个，为什么？ HTTP_HOST从HTTP请求头获得，这就是客户端实际用作请求的“目标主机”的内容。 SERVER_NAME在服务器配置中定义。 要使用哪一个取决于你需要什么。 然而，您现在应该意识到，这是一个客户端控制的值，因此可能不适用于业务逻辑，另一个是服务器控制的值更可靠。 但是，您需要确保所涉及的Web服务器具有正确配置的SERVER_NAME 。 以Apache HTTPD为例，下面是它的文档摘录： 如果未指定Serve
Actually I want to read the contents that come after the search query, when it is done. The problem is that the URL only accepts POST methods, and it does not take any action with GET method... I have to read all contents with the help of domdocument or file_get_contents() . Is there any method that will let me send parameters with POST method and then read the contents via PHP ? CURL-less
其实我想读取搜索查询后的内容，当它完成时。 问题是该URL只接受POST方法，并且不会对GET方法执行任何操作... 我必须在domdocument或file_get_contents()的帮助下阅读所有内容。 有没有什么方法可以让我用POST方法发送参数，然后通过PHP读取内容？ 使用PHP5的CURL-less方法： $url = 'http://server.com/path'; $data = array('key1' => 'value1', 'key2' => 'value2'); // use key 'http' even if you send the re
I want to do var_export() and strip out all numerical array keys on an array. My array outputs like so: array ( 2 => array ( 1 => array ( 'infor' => 'Radiation therapy & chemo subhead', 'PPOWithNotif' => '', 'PPOWithOutNotif' => 'Radiation therapy & chemo PPO amount', 'NonPPO' => 'Radiation therapy & chemo Non PPO amount',
我想做var_export（）并去掉数组上的所有数字数组键。 我的数组输出如下所示： array ( 2 => array ( 1 => array ( 'infor' => 'Radiation therapy & chemo subhead', 'PPOWithNotif' => '', 'PPOWithOutNotif' => 'Radiation therapy & chemo PPO amount', 'NonPPO' => 'Radiation therapy & chemo Non PPO amount', ), ), 3 => array (
