I used to get different MIMI types when using finfo_open(FILEINFO_MIME_TYPE). For instance, based on memory, I believe docx were application/vnd.openxmlformats-officedocument.wordprocessingml.document (see this StackOverflow post What is a correct mime type for docx, pptx etc?). I also recall them showing as application/zip, but that might have been when using mime_content_type(). Also, thoug
在使用finfo_open(FILEINFO_MIME_TYPE)时,我曾经使用过不同的MIMI类型。 例如,基于内存,我相信docx是application / vnd.openxmlformats-officedocument.wordprocessingml.document(请参阅此StackOverflow文章什么是docx,pptx等的正确MIME类型?)。 我还记得他们显示为应用程序/ zip,但可能是使用mime_content_type()时。 另外,认为js文件是作为application / x-javascript发布的。 以下是我现在正在与脚本一起
I am writing custom file validation through mimetype on my local server php version is 5.4.22 and it returns "docx" file mimetype "application/vnd.openxmlformats-officedocument.wordprocessingml.document; charset=binary" that is correct for me. But on my server there is php version 5.3.3 and it returns "docx" file mimetype "application/zip; charset=binary"
我正在通过本地服务器上的mimetype编写自定义文件验证,php版本是5.4.22,它返回对我来说正确的“docx”文件mimetype“application / vnd.openxmlformats-officedocument.wordprocessingml.document; charset = binary”。 但在我的服务器上有PHP版本5.3.3,它返回“docx”文件mimetype“application / zip; charset = binary”,这是不正确的,我的验证在这里失败。 请建议我必须做什么,我应该将服务器5.3.3上的php版本升级到php最
My Laravel 4.2 php project has export to excel feature, which is working on desktop but totally not working on mobile devices. I am saving the excel file with "XLS" extension and "application/vnd.ms-excel" content type: $fn = 'filename.xls'; $filename = storage_path() .

我的Laravel 4.2 php项目已导出为excel功能,该功能在桌面上工作,但完全不适用于移动设备。 我正在保存带有“XLS”扩展名和“application / vnd.ms-excel”内容类型的excel文件: $fn = 'filename.xls'; $filename = storage_path() . '/' . $fn; App::finish(function($request, $response) use ($filename) { unlink($filename); }); $headers = array(....); $
I'm building a simple file upload/file download functionality into my database. The only complicated part is that all files need to be encrypted using my fancy-shmancy encryption methods. So what I do is make an SQL entry that stores things like: id_file, filename, extension, size, dateadded, etc Then once I've got the id_file I take the file contents, encrypt them, then save the con
我正在建立一个简单的文件上传/文件下载功能到我的数据库中。 唯一复杂的部分是所有文件都需要使用我的花式嘘声加密方法进行加密。 所以我所做的是创建一个SQL条目,它存储如下内容:id_file,文件名,扩展名,大小,dateadded等 然后,一旦我获得了id_file,我将文件内容加密,然后将它们加密,然后将内容作为[id_file] .txt保存到我的服务器。 然后这里是再次下载文件的代码: header("Pragma: public"); header('Conte

Microsoft Word (.docx) files download perfectly, but when downloading an excel (xlsx) file, excel gives a "This file is corrupt and cannot be opened" dialog.

我在一个允许教师上传文件和学生下载它们的网站上工作。 但是,有一个问题。 Microsoft Word(.docx)文件完美下载,但在下载Excel(xlsx)文件时,Excel会提供“此文件已损坏且无法打开”对话框。 任何帮助,将不胜感激! 我的下载代码如下: case 'xlsx': header('Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); header('Content-Disposition: attachment; filename="' . $
The form on my website is a simple contact form. I would like the form to show a "success & failed" message on the same page when the form is sent/failed without reloading the page. I understand that I should use Ajax to do this but I can't get it to work because my knowledge about it is very little. Here is the code I'm working with. Html (single page design): &l
我网站上的表格是一个简单的联系表格。 当表单发送/失败而不重新加载页面时,我希望表单在同一页面上显示“成功与失败”消息。 我明白我应该使用Ajax来做到这一点,但是我无法实现它,因为我对此的了解很少。 这是我正在使用的代码。 Html(单页设计): <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.js"></script> <form class="form" id="contactus" action="" method="po
I have a barcode scanner and laptop (ofcourse :)), I'm looking for simple event management app that can process the input from the barcode scanner and keep attendance record for our frequent private meetings. I wonder if there's an open source software available that'd allow me to manage events using code 128 barcode id cards? Many thanks for your help. DIY. Seriously, this wou
我有条形码扫描仪和笔记本电脑(ofcourse :)),我正在寻找简单的事件管理应用程序,可以处理来自条形码扫描仪的输入信息,并为我们经常举行的私人会议保留出席记录。 我想知道是否有开源软件可以让我使用128码条形码卡管理事件? 非常感谢您的帮助。 DIY。 说真的,这将是一个完美的项目。 如果你倾向于这种方式! 如果您的条形码扫描仪遵循接口(串行等)和协议中的一些标准,那么PHP将能够读取数据。 之后,它是一
I downloaded Google speed tracer for Google chrome to see how my site does performance wise and it tells me I need to enable caching for certain files like my style.css, images, etc. I've read that the below php code should tell browsers to cache html content. I wrote a quick php page with a couple of images on it and stuck the below code at the top (before the headers are sent) to test to
我下载了谷歌Chrome浏览器的谷歌速度追踪器,以查看我的网站的性能是否明智,并告诉我需要为像style.css,图像等某些文件启用缓存。 我读过下面的PHP代码应该告诉浏览器缓存html内容。 我写了一个快速的PHP页面,其中包含一些图片,并将下面的代码粘贴在顶部(在发送标题之前)以测试它的工作方式。 Header("Cache-Control: public, max-age=3600, must-revalidate"); 当我追溯速度追踪者的分析时,它说... 摘要来自缓存

我们为我们的客户开发了电子学习网站。 最近他问他需要SCORM饲料。 我宿舍知道我的系统是否与scrom兼容。 做任何机构知道任何开源的PHP工具或lib从现有的数据生成scrom。 谢谢 您需要确定的第一件事是您的网站是否会被视为学习管理系统或内容。 根据您尝试开发的内容,SCORM的实施情况差别很大。 查看http://www.scorm.com/scorm-explained/了解SCORM的一个很好的解释,以及它是如何工作的。 我已经尝试了Chamilo 1.9.6
I'm considering switching to mysqli for all my php projects. The way my code is written (I run very simple websites and built my own basic framework which I use across all of them) I shouldn't have too many problems modifying the functions and classes. However, i've only heard positive things about prepared statements, bar a few grumblings about the php functions available, most no
我正在考虑切换到所有我的PHP项目的mysqli。 我的代码编写的方式(我运行非常简单的网站,并构建了我自己的基本框架,我使用它们)我不应该有太多修改函数和类的问题。 然而,我只听到了有关准备好的语句的积极的事情,请留心一些关于可用的PHP函数的问题,特别是在一段时间内没有简单替换使用mysql_fetch_array。 这听起来有点太好了,所以我想知道是否有人能够强调使用准备语句的一些问题,例如速度和资源使用情况。 如
