Amazon S3 Server provides large disk space for the web data storage the complete advantage of the cloud computing is another example of S3 sever .The Amazon S3 file upload using the php api is now pretty simple and most secure.The most advantage of the system is the code running server (EC2) and File storage Server (S3) is separate that means for every request for file it give the risk to S3 server so the risk on your EC2 sever will reduce and performance will improved. Here i just explain How we can upload a file (any type) to Amazon S3 server using php api. The fist step is you have to signup with the Amazon server for getting the credentials. check here.

Amazon S3 file Upload using php api

The next step is to get the S3.php  for manage s3 operation from here. when you get the S3 access key and secret key then you can start playing on the S3 server with this AWS SDK with php.

Before starting with Amazon s3 file upload using php api ,just an explanation about buckets. The word bucket is used for representing the s3 server folders(kind of). These are unique and have two access level Private and Public. Based on this access level the file access provides. The bucket you can access like

http://mybucket.s3.amazonaws.com/your_filename

For Basic Operations check the following codes.

File Upload From Your Sever(EC2).

<?php
if (!class_exists('S3'))require_once('S3.php');
//AWS access info
if (!defined('awsAccessKey')) define('awsAccessKey', 'YourAccess S3 Key');
if (!defined('awsSecretKey')) define('awsSecretKey', 'Yor Secret Key');
//instantiate the class
$s3 = new S3(awsAccessKey, awsSecretKey);
$s3->putBucket("bucket name", S3::ACL_PRIVATE); //sec param specify the access level
//move the file to s3 server
if ($s3->putObjectFile("your file name in the server with path", "which bucket ur using (bucket name)", "fine name in s3 server", S3::ACL_PRIVATE)) {
//s3 upload success
}
 ?>

Get an object on s3

S3::getObject($bucketName, $uploadName)

For copy an object using

S3::copyObject($srcBucket, $srcName, $bucketName, $saveName, $metaHeaders = array(), $requestHeaders = array())

For Delete

S3::deleteObject($bucketName, $uploadName)

And Basic Operation on buckets are like

S3::listBuckets() // Simple bucket list
S3::listBuckets(true) // Detailed bucket list

For more details about the S3 operation you can read this.

Good Luck 🙂
