copy() Copy an object from one location to another. You can pass options available to the CopyObject

operation into the stream context options to modify how the object is copied.

// Copy a file on Amazon S3 to another bucket

copy('s3://bucket/key', 's3://other_bucket/key');

Working with buckets

You can modify and browse Amazon S3 buckets similar to how PHP allows the modification and traversal of

directories on your filesystem.

Here's an example of creating a bucket:

mkdir('s3://bucket');

You can pass in stream context options to the mkdir() method to modify how the bucket is created using the

parameters available to the CreateBucket operation.

// Create a bucket in the EU region

mkdir('s3://bucket', stream_context_create(array(

's3' => array(

'LocationConstraint' => 'eu-west-1'

)

));

You can delete buckets using the rmdir() function.

// Delete a bucket

rmdir('s3://bucket');

Note

A bucket can only be deleted if it is empty.

Listing the contents of a bucket

The opendir(), readdir(), rewinddir(), and closedir() PHP functions can be used with the Amazon S3 stream wrapper

to traverse the contents of a bucket. You can pass in parameters available to the ListObjects operation as custom

stream context options to the opendir() function to modify how objects are listed.

$dir = "s3://bucket/";

if (is_dir($dir) && ($dh = opendir($dir))) {

while (($file = readdir($dh)) !== false) {

echo "filename: {$file} : filetype: " . filetype($dir . $file) . "\n";

}

closedir($dh);

}

You can recursively list each object and prefix in a bucket using PHP's RecursiveDirectoryIterator.

$dir = 's3://bucket';

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir));

foreach ($iterator as $file) {

echo $file->getType() . ': ' . $file . "\n";

}
