I'd like to check if an uploaded file is an image file (eg png, jpg, jpeg, gif, bmp) or another file. The problem is that I'm using Uploadify to upload the files, which changes the mime type and gives a 'text/octal' or something as the mime type, no matter which file type you upload. Is there a way to check if the uploaded file is an image apart from checking the file extension
我想检查一个上传的文件是否是一个图像文件（如PNG，JPG，JPEG，GIF，BMP）或其他文件。 问题是我正在使用Uploadify上传文件，这些文件会更改MIME类型，并给出“文本/八进制”或其他类型的MIME类型，无论您上传的是哪种文件类型。 有没有办法检查上传的文件是否是一个图像，除了使用PHP检查文件扩展名？ 你可以使用getimagesize() ，它在非图像上返回零大小。 我对这个主题的想法很简单：所有上传的图像都是邪恶的。 不仅因
'<?php $allowedExts = array("jpg", "jpeg", "gif", "png"); $extension = end(explode(".", $_FILES["file"]["name"])); if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/png") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 20000) && in_array($extension, $allowedExts))
'<?php $allowedExts = array("jpg", "jpeg", "gif", "png"); $extension = end(explode(".", $_FILES["file"]["name"])); if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/png") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 20000) && in_array($extension, $allowedExts))
I am programming a script to upload images to my application. Are the following security steps enough to make the application safe from the script side? Disable PHP from running inside the upload folder using .httaccess. Do not allow upload if the file name contains string "php". Allow only extensions: jpg,jpeg,gif and png. Allow only image file type. Disallow image with two
我正在编写脚本将图像上传到我的应用程序。 以下安全措施足以使应用程序从脚本端安全吗？ 使用.httaccess禁用PHP在上传文件夹内运行。 如果文件名包含字符串“php”，则不允许上传。 只允许扩展名：jpg，jpeg，gif和png。 只允许图像文件类型。 不允许使用两种文件类型的图像。 更改图像名称。 上传到不是根目录的子目录。 这是我的脚本： $filename=$_FILES['my_files']['name']; $filetype=$_FILES['my_files
I have a PHP REST API has written with SLIM Framework, I have an api call which creates a docx file and force the file to be downloaded. $filename = 'invitation.docx'; $templateProcessor->save($filename); header('Content-Description: File Transfer'); header('Content-type: application/force-download'); header('Content-Disposition: attachment; filename='.basename($filename));

I'm downloading a file through php script and everything work perfectly except one ugly truth. The downloaded file keep the same url and with original name appended. How do I maintain the same filename when file downloaded? http://bachday.com/index.php?page=custom&file=mmailer/download.php?mfile=sample.docx if (isset($_GET['mfile'])) { $file = $_SERVER['DOCUMENT_ROOT'].'/oc-content/p
我正在通过php脚本下载一个文件，除了一个丑陋的事实，一切都很完美。 下载的文件保持相同的URL并附有原始名称。 文件下载时如何保持相同的文件名？ http://bachday.com/index.php?page=custom&file=mmailer/download.php?mfile=sample.docx if (isset($_GET['mfile'])) { $file = $_SERVER['DOCUMENT_ROOT'].'/oc-content/plugins/mmailer/pfile/'.$_GET['mfile']; if (file_exists($file) && is_readable($file)
I have a problem: I trying to send headers, but nothing happens. This is a part of the headers from "Live HTTPHeaders"(i replaced the url): http://some_site/news/ POST /news/ HTTP/1.1 Host: some_site User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,

So, I was wondering if there was a way to see if one could use bash to kill a PID of a process if more than X amount spawned. For example: Let's say we have 10 php processes running with separate PIDs all with the command /usr/bin/php. If it hit 10 processes, would there be a way to kill it with a bash script? (I'll be having this script run full time in the foreground with a termina
所以，我想知道是否有一种方法来查看是否可以使用bash杀死一个进程的PID，如果产生的X数量多于X的话。 例如： 假设我们有10个使用命令/ usr / bin / php运行的php进程，使用单独的PID运行。 如果它击中了10个进程，是否有办法用bash脚本杀死它？ （我会让这个脚本全程运行在一个终端的前台） 恕我直言，你正在解决错误的问题。 我宁愿确保进程本身不能有多个实例（这里是一个实现清单），并通过某种指令堆栈提供指令。

I can't seem to figure this out and I've tried everything. I want a form to submit my data as a JSON, and then head to a PHP page, where it outputs the results from the JSON data. I have it set as the following but this does absolutely nothing. Form code: <form name="login" onsubmit="SendForm();"> <input class="textbox" type="text" name="username" placeholder="Username"
