To search images in S3 folder by keywords - php

Question

What is the best and simple way to search and get images list from S3 by using English keywords. Or do I have to use the Rekognition to store all the image metadatas into database?
My development is using Php.

Answer 1

<?php
require 'vendor/autoload.php';
use Aws\S3\S3Client;
use Aws\S3\Exception\S3Exception;
$bucket = '*** Your Bucket Name ***';
// Instantiate the client.
$s3 = new S3Client([
'version' => 'latest',
'region' => 'us-east-1'
]);
// Use the high-level iterators (returns ALL of your objects).
try {
$objects = $s3->getPaginator('ListObjects', [
'Bucket' => $bucket
]);
echo "Keys retrieved!" . PHP_EOL;
foreach ($objects as $object) {
echo $object['Key'] . PHP_EOL;
}
} catch (S3Exception $e) {
echo $e->getMessage() . PHP_EOL;
}
// Use the plain API (returns ONLY up to 1000 of your objects).
try {
$result = $s3->listObjects([
'Bucket' => $bucket
]);
echo "Keys retrieved!" . PHP_EOL;
foreach ($result['Contents'] as $object) {
echo $object['Key'] . PHP_EOL;
}
} catch (S3Exception $e) {
echo $e->getMessage() . PHP_EOL;
}
so this code will return you all objects in your bucket, you can add logic that only iff the key contains the extension 'jpg', 'jpeg' , and 'png' then only you have to print the key/name of object

Answer 2

You can list all the objects and find the ones you are looking for
In pseudo-code
connect to S3
list thru all buckets ( or specify a bucket )
for object in bucket.objects.all
if object.key = your search criteria
do something
I have a code does this for me in python, let me know if you like me to post it, since you are using php I gave you the logic in pseudo code above
