Create a subfolder inside this folder called uploads this is where our uploaded files will be stored , and a file called index. Open it and put this code inside it:. In the head section, we are linking to our style. Create that file in the root of our application and add this CSS code to it:.
At the top of index. This is the file that contains all the logic of receiving our submitted file and saving it to the uploads folder as well as storing the file information in the database. Let's create this file now. At the top of this file, we are connecting to a database but we've not yet created it yet. You can download the file by selecting the Save File radio button and pressing the OK button.
If the file exists at the given file location, the file path will be required to mention in the URL. In this example, we will create an HTML file with the following code, which will pass the filename with the file path:. We will create a PHP file with the following code to download a file from the file path. The PHP code in the previous example will be slightly modified to download the file from the given path. The clearstatecache function is used to clear the cache that was previously stored.
Two arguments are used in the readfile function. Output After the download link of the PDF file is clicked, the following output will appear. Hi, Can you suggest me on how can I verify that my file is uploaded correctly to the server? You can create a script on the server that expects two values: a checksum and a filename. Then you can post those two values using a cURL.
The server will then calculate the checksum of the existing file and compare it to what you sent. So, the first request uploads the file, and the second request verifies it. I have the following requirement Upload a jpg format image to jpegmini server and receive the compressed image as the response. Please note that the jpegmini URL is an AWS instance I am stopping the instance when not using it If you want me to run the instance please let me know.
If so, have you already tried converting it to PHP and were unsuccessful? As you define in your blog, I have same folllow the above steps to upload and download files using curl, but its not working anymore. Can you define by the examples. So I can understand easily. Linking to external tutorial not helpful.
The answers above me works. Mo Chan Mo Chan 7 7 bronze badges. Zevan 9, 3 3 gold badges 30 30 silver badges 47 47 bronze badges. Assasin Assasin 21 1 1 bronze badge. Welcome to StackOverflow. It's always advisable to include the code directly instead of adding a link to avoid the link issues.
You can stream download too which will consume significantly less resource. Saud Qureshi Saud Qureshi 1, 11 11 silver badges 20 20 bronze badges. What do you mean by the download is streamed?
ParsaYazdani It means the downloaded data will be chunked. Please look onto the concept of streaming for more details. Note: this is not the only to stream chunk download the file in PHP. But it surely is one of the easiest methods.
Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. If you have output buffering, the file will not be sent to the user in chunks but only at the end of the script. At the start of your script, after checking the file if it exists, etc. Be aware that multiple ranges can be specified e.
If the range is not valid, you must output. Do not try to guess or fix the range s as it may result in corrupted downloads, which are more dangerous than failed ones.
Many developers forget to send the code or the Accept-Ranges. Yet others forget that when you send a range, the Content-Length must match the length of the range rather than the size of the whole file.
You can output the file using the method described above, skipping until the start of the range and delivering the length of the range. I did my best to provide only accurate information. It would be truly sad for me if an article about avoiding common PHP errors contained errors itself. Regardless, my point stands: PHP makes it easy to hack together code that appears to be working, but developers should read and adhere to the official specifications.
