I want to upload a file from an external URL directly to an Amazon S3 bucket using the PHP SDK. I managed to do this with the following code:
$s3 = new AmazonS3();
$response = $s3->create_object($bucket, $destination, array(
'fileUpload' => $source,
'length' => remote_filesize($source),
'contentType' => 'image/jpeg'
));
Where the function remote_filesize is the following:
function remote_filesize($url) {
ob_start();
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
$ok = curl_exec($ch);
curl_close($ch);
$head = ob_get_contents();
ob_end_clean();
$regex = '/Content-Length:\s([0-9].+?)\s/';
$count = preg_match($regex, $head, $matches);
return isset($matches[1]) ? $matches[1] : "unknown";
}
However, it would be nice if I could skip setting the filesize when uploading to Amazon since this would save me a trip to my own server. But if I remove setting the 'length' property in the $s3->create_object function, I get an error saying that the 'The stream size for the streaming upload cannot be determined.' Any ideas how to solve this problem?
Navigate to All Settings > Raw Data Export > CSV Upload. Toggle the switch to ON. Select Amazon S3 Bucket from the dropdown menu. Enter your Access Key ID, Secret Access Key, and bucket name.
You can upload file from url directly to Amazon S3 like this (my example is about a jpg picture):
1. Convert the content from url in binary
$binary = file_get_contents('http://the_url_of_my_image.....');
2. Create an S3 object with a body to pass the binary into
$s3 = new AmazonS3();
$response = $s3->create_object($bucket, $filename, array(
'body' => $binary, // put the binary in the body
'contentType' => 'image/jpeg'
));
That's all and it's very fast. Enjoy!
