Q:

PHP move_uploaded_file() function (with example)

Hey everyone,

I've been working on a web project where I need to allow users to upload files to my website. I came across the move_uploaded_file() function in PHP, but I'm a bit confused about how it works.

From what I understand, move_uploaded_file() is used to move an uploaded file to a new location on the server. But I'm not sure about the syntax and how to actually use this function in my code.

I have the file upload feature working fine, but I want to move the uploaded file from the temporary location to a specific folder on the server. Can someone please provide me with a clear example of how to use the move_uploaded_file() function?

Any help would be greatly appreciated!

Hey there,

I've faced a similar situation in one of my recent projects and found move_uploaded_file() to be really handy. Let me explain how I used it in a slightly different context.

In my project, I had a form where users could upload profile pictures. My goal was to move the uploaded image to a specific folder on the server and rename it to match the user's unique ID. Here's an example that demonstrates this:

php
// Assuming you have retrieved the user's unique ID from your database
$userId = 123;

// Retrieve the temporary path of the uploaded file
$uploadedFile = $_FILES['profilePicture']['tmp_name'];

// Determine the destination path and desired file name
$destinationFolder = '/path/to/destination/folder/';
$newFileName = $userId . '.jpg';
$destination = $destinationFolder . $newFileName;

// Use move_uploaded_file() function to move and rename the file
if (move_uploaded_file($uploadedFile, $destination)) {
echo "Profile picture uploaded and saved successfully!";
} else {
echo "Oops! Something went wrong while saving the profile picture.";
}


In this case, I retrieved the user's ID from my database and used it to construct the new file name by appending '.jpg' extension. Make sure you adjust the file extension based on the type of files you're dealing with.

By using move_uploaded_file(), the uploaded profile picture is securely moved from the temporary location to the designated folder while also renaming it with the user's ID. This helps me maintain a consistent naming convention and ensures uniqueness.

Feel free to let me know if you have any questions or need further assistance. Happy coding!

Hey there,

I've used the move_uploaded_file() function in my web projects quite a few times, so I'll be happy to help you out!

To use the move_uploaded_file() function, you need to provide two parameters: the temporary path of the uploaded file and the desired destination path where you want to move the file.

Here's an example to give you a better understanding:

php
// Assuming you have a form with a file input named 'fileUpload'
$uploadedFile = $_FILES['fileUpload']['tmp_name'];

// Specify the destination folder where you want to move the file
$destination = '/path/to/destination/folder/' . $_FILES['fileUpload']['name'];

// Now, use move_uploaded_file() function to move the file
if (move_uploaded_file($uploadedFile, $destination)) {
echo "File moved successfully!";
} else {
echo "Oops! Something went wrong.";
}


In this example, `$uploadedFile` represents the temporary path of the uploaded file, which you can access through the `$_FILES` superglobal array. `$destination` is the desired path where you want to move the file. Make sure you have appropriate write permissions for the destination folder.

If the move_uploaded_file() function returns true, it means the file has been successfully moved. Otherwise, an error occurred, and you can handle it accordingly.

I hope this clears things up for you! Let me know if you have any further questions.
