How to send files using PHP and cURL
In this tutorial we want to upload a file to other (password protected) remote FTP server using a web form.
<?php
if (isset($_POST['Submit'])) {
if (!empty($_FILES['file']['name'])) {
$ch = curl_init();
$uploadedfile = $_FILES['file']['tmp_name'];
$fp = fopen($uploadedfile , 'r');
curl_setopt($ch, CURLOPT_URL, 'ftp://target_ftp_login:[email protected]/'.$_FILES['file']['name']);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($uploadedfile ));
curl_exec ($ch);
$error_msg = curl_errno($ch);
curl_close ($ch);
if ($error_msg == 0) {
$response = 'Yours File uploaded successfully.';
} else {
$response = 'Error into upload file.';
}
} else {
$response = 'Please select a file.';
}
echo $response ;
}
?>
