To handle file uploads in PHP, you can use the $_FILES superglobal variable, which contains information about the uploaded files. Here's an example of how to handle file uploads:
HTML form:
PHP script (upload.php):
In this example, the HTML form has an input field with the name "fileToUpload" that allows the user to select a file. When the form is submitted, the file is sent to the PHP script specified in the form's `action` attribute (upload.php in this case).
In the PHP script, $_FILES["fileToUpload"] represents the uploaded file. The ["name"] key provides the original name of the file, and ["tmp_name"] contains the temporary location of the file on the server.
The script checks if a file was uploaded successfully by checking the $_FILES["fileToUpload"]["error"] value. If it is UPLOAD_ERR_OK (0), the file was uploaded without any errors.
To store the uploaded file, move_uploaded_file() function is used. It moves the file from its temporary location to the target directory specified by $targetFile. If the file is moved successfully, it confirms the successful upload; otherwise, it displays an error message.
Make sure that the target directory has appropriate write permissions so that PHP can move the file to that location.
Remember to handle file validation and security measures when dealing with file uploads, such as checking file types, file size limitations, and ensuring secure storage of uploaded files.
