I americium connected AWS SDK for PHP V2.eight.7 moving connected PHP 5.three.
I americium making an attempt to link to my Amazon S3 bucket with the pursuing codification:
// Make a `Aws` entity utilizing a configuration record $aws = Aws::mill('config.php'); // Acquire the case from the work locator by namespace $s3Client = $aws->acquire('s3'); $bucket = "xxx"; $keyname = "xxx"; attempt { $consequence = $s3Client->putObject(array( 'Bucket' => $bucket, 'Cardinal' => $keyname, 'Assemblage' => 'Hullo Planet!' )); $file_error = mendacious; } drawback (Objection $e) { $file_error = actual; echo $e->getMessage(); dice(); }
My config.php record is arsenic follows:
