$filetype = $_FILES["anyfile"]["type"];
$filesize = $_FILES["anyfile"]["size"];
// Validate file extension
$ext = pathinfo($filename, PATHINFO_EXTENSION);
if(!array_key_exists($ext, $allowed)) die("Error: Please select a valid file format.");
// Validate file size - 10MB maximum
$maxsize = 10 * 1024 * 1024;
if($filesize > $maxsize) die("Error: File size is larger than the allowed limit.");
// Validate type of the file
if(in_array($filetype, $allowed)){
// Check whether file exists before uploading it
if(file_exists("upload/" . $filename)){
echo $filename . " is already exists.";
} else{
if(move_uploaded_file($_FILES["anyfile"]["tmp_name"], "upload/" . $filename)){
$bucket = 'YOUR_BUCKET_NAME';
$file_Path = __DIR__ . '/upload/'. $filename;
$key = basename($file_Path);
try {
$result = $s3Client->putObject([
'Bucket' => $bucket,
'Key' => $key,
'Body' => fopen($file_Path, 'r'),
'ACL' => 'public-read', // make file 'public'
]);
echo "Image uploaded successfully. Image path is: ". $result->get('ObjectURL');
} catch (Aws\S3\Exception\S3Exception $e) {
echo "There was an error uploading the file.\n";
echo $e->getMessage();
}
echo "Your file was uploaded successfully.";
}else{
echo "File is not uploaded";
