How to Save Uploaded Files with a Custom Name in PHP?

Saving Files with Desired Name

When uploading and saving files with PHP, you may encounter a scenario where you wish to assign a specific name to the saved file. By default, the server will assign the original filename.

Let's consider the following code:

$target_Path = "images/";
$target_Path = $target_Path.basename($_FILES['userFile']['name']);
move_uploaded_file($_FILES['userFile']['tmp_name'], $target_Path);

If you attempt to save the file as "myFile.png" by replacing the following line:

$target_Path = $target_Path.basename($_FILES['userFile']['name']);

with:

$target_Path = $target_Path.basename("myFile.png");

it will not work.

To achieve this, you can extract the extension of the uploaded file and append it to your desired filename:

$info = pathinfo($_FILES['userFile']['name']);
$ext = $info['extension']; // get the extension of the file
$newname = "newname.".$ext; 

$target = 'images/'.$newname;
move_uploaded_file($_FILES['userFile']['tmp_name'], $target);

By following these steps, you can save the uploaded file with your desired name while maintaining the correct file extension.
