Here is an example of a PHP file upload script:
<?php
// Set the directory where the uploaded file will be saved
$upload_dir = 'uploads/';
// Check if the file was uploaded
if (isset($_FILES['fileToUpload'])) {
// Check if the file is an image
if ($_FILES['fileToUpload']['type'] == 'image/jpeg' || $_FILES['fileToUpload']['type'] == 'image/png') {
// Get the file name and extension
$file_name = $_FILES['fileToUpload']['name'];
$file_extension = pathinfo($file_name, PATHINFO_EXTENSION);
// Create a new file name for the uploaded file
$new_file_name = uniqid() . '.' . $file_extension;
// Move the uploaded file to the upload directory
move_uploaded_file($_FILES['fileToUpload']['tmp_name'], $upload_dir . $new_file_name);
// Success!
echo "File uploaded successfully!";
} else {
// Error! The file is not an image
echo "File is not an image.";
}
} else {
// Error! No file was uploaded
echo "No file was uploaded.";
}
?>
This script will first check if the file was uploaded. If it was, the script will check if the file is an image. If it is, the script will create a new file name for the uploaded file and move it to the upload directory. Finally, the script will display a message indicating whether or not the file upload was successful.
Here is an example of the HTML form that can be used with this script:
HTML
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="fileToUpload">
<input type="submit" value="Upload">
</form>
When the user clicks the "Upload" button, the file will be uploaded to the server and the PHP script will be executed.
