Delete a single file from AWS s3 bucket? - php

Question

I am trying to delete a single file from AWS s3 bucket and my code is as below:
$removeUploadedDocFromTestingFolder = array(
"removeFromTestFolder" =>
array(
"bucket" => "my-bucket"
),
"AccessKeys" =>
array(
"access_key" => "my access key",
"seceret_key" => "my secret key"
)
);
$_SERVER['HOME'] = DIR_HOME;
ini_set('display_errors',1); error_reporting(E_ALL);
use Aws\S3\S3Client;
use Aws\Common\Credentials\Credentials;
$client = S3Client::factory();
//$objError = new ErrorReporting();
$bucket = $removeUploadedDocFromTestingFolder['removeFromTestFolder']['bucket'];
//testing file setup on local server....
$file1 = "my-file";
//File reference on cloud.....Object URL
$file1_cloud = "https://Object URL/myFile/myFile";
echo "here 0";
$client->deleteObject($bucket, $file1_cloud);
Can anyone tell what I am doing wrong that the code is not deleting the file.
I tried the following code but it didn't work:
try {
//$client->deleteObject($bucket, $file1_cloud);
$result = $client->deleteObject(['Bucket' => 'my-bucket','Key' => 'myFile.png']);
} catch(\Aws\S3\Exception\S3Exception $e) {
echo "error"+$e;
}
Thanks

Answer 1

The object is not being deleted because you have asked S3 to delete a non-existent object, and S3 treats this as a no-op rather than an error. This is because you have indicated a URL rather than the key of the object.
An example of an S3 object key is:
testing/cats/fluffykins.png
Note that it's not a URL and it doesn't begin with forward slash.
An example of the correct way to call the PHP deleteObject function is:
$result = $s3Client->deleteObject([
'Bucket' => $bucket,
'Key' => $key,
]);
Note that it takes an array of parameters, including bucket and key. It assumes PHP 5.4 or later in which you can use the short array syntax, which replaces array() with [].

I've resolved the issue by using the following code:
$client = S3Client::factory(array(
'key' => "mykey",
'secret' => "my secret key"
));
//File reference on cloud.....
$file1_cloud = "TestFile/myFile.png";
$result = $client->deleteObject(array(
'Bucket' => $bucket,
'Key' => 'TestFile/myFile.png'));
