Using S3 to upload in PHP using PHP DI - php

Question

I am using dependency injector to setup S3's credentials:
// AWS S3 for PDF
$container['s3_pdf'] = function ($c) {
// Only load credentials from environment variables.
$provider = CredentialProvider::env();
$s3 = new Aws\S3\S3Client([
'version' => 'latest',
'region' => 'ap-southeast-2',
'credentials' => $provider
]);
return $s3;
};
Then whenever I want to upload something I'd do:
$result = $this->s3_pdf->putObject(array(
'Bucket' => 'reports.omitted.com',
'Key' => 'temptest1.pdf',
'SourceFile' => 'assets/temp.pdf',
'ContentType' => 'text/plain',
'ACL' => 'public-read',
'StorageClass' => 'REDUCED_REDUNDANCY',
'Metadata' => array(
'param1' => 'value 1',
'param2' => 'value 2'
)
));
I want to be able to upload to S3 from different functions in the code without having to write the bucket name everytime, am I able to have the s3_pdf container return a function that only takes sourcefile and runs some code to figure out the sourcefile & destination & uploads to S3?
I know that I can use a class that would contain this function I'm after and use an object of that class in the functions where I need S3 but I'd rather use the dependency container if there is a way to do so.

Answer 1

This is the simplest example of my suggested wrapper function possible:
class WhateverYourClassIs
{
function putObject( $key, $sourceFile )
{
return $this->s3_pdf->putObject(array(
'Bucket' => 'reports.omitted.com',
'Key' => $ke,
'SourceFile' => $sourceFile,
'ContentType' => 'text/plain',
'ACL' => 'public-read',
'StorageClass' => 'REDUCED_REDUNDANCY',
'Metadata' => array(
'param1' => 'value 1',
'param2' => 'value 2'
)
));
}
}
Or with an array
class WhateverYourClassIs
{
function putObject( $overloadedConfig )
{
$baseConfig = array(
'Bucket' => 'reports.omitted.com',
'Key' => NULL,
'SourceFile' => NULL,
'ContentType' => 'text/plain',
'ACL' => 'public-read',
'StorageClass' => 'REDUCED_REDUNDANCY',
'Metadata' => array()
);
return $this->s3_pdf->putObject( array_merge_recursive( $baseConfig, $overloadedConfig ) );
}
}
$this->putObject(array(
'Key' => 'temptest1.pdf',
'SourceFile' => assets/temp.pdf'
));
