How to Get All Redis Keys In Cache In Laravel?

To get all Redis keys in cache in Laravel, you can use the keys method provided by the Redis facade. This method takes a wildcard pattern as an argument and returns an array of all keys that match the pattern. For example, you can get all keys in the cache by passing * as the wildcard pattern:

1

$keys = Redis::connection()->keys('*');

This will return an array of all keys in the cache. Keep in mind that using this method can be performance-intensive, especially with a large number of keys in the cache. It is recommended to use it sparingly and only when necessary.

What is the syntax to access all keys from Redis cache in Laravel?

To access all keys from Redis cache in Laravel, you can use the following syntax:

1

$keys = Redis::connection()->keys('*');

This code snippet will retrieve all keys stored in the Redis cache. Make sure you have the Redis service provider registered in your config/app.php file and have the Redis facade imported at the top of your file:

1

use Illuminate\Support\Facades\Redis;

What PHP function can I use to retrieve all keys from Redis cache in Laravel?

You can use the keys method in Laravel to retrieve all keys from the Redis cache. Here's an example:

1

$keys = Redis::keys('*');

This will retrieve all keys from the Redis cache that match the given pattern (in this case, * will match all keys). You can then use the $keys array to access and manipulate the keys as needed.

What is the command to display all keys in Redis cache in Laravel framework?

To display all keys in the Redis cache in Laravel framework, you can use the following command:

1

php artisan redis:keys

This command will list all keys present in the Redis cache.

What is the function to get all keys from Redis cache in Laravel application?

In Laravel, you can use the keys() method to retrieve all keys from the Redis cache. Here is an example code snippet:

1
2
3
4
5
6
7

use Illuminate\Support\Facades\Redis;

$keys = Redis::keys('*');

foreach ($keys as $key) {
    echo $key . "\n";
}

This code snippet uses the Redis facade to access the Redis cache and fetch all keys using the keys('*') method. Then, it iterates over the keys and prints them out to the console.

What is the technique to count the total number of keys in Redis cache in Laravel?

In Laravel, you can count the total number of keys in a Redis cache by using the scan method provided by the Illuminate\Support\Facades\Redis facade.

Here is an example of how you can count the total number of keys in a Redis cache in Laravel:

1
2
3
4
5
6
7
8
9

use Illuminate\Support\Facades\Redis;

// Get the keys using the scan method
$keys = Redis::scan(0, 'MATCH', '*');

// Count the total number of keys
$totalKeys = count($keys[1]);

echo "Total number of keys in Redis cache: " . $totalKeys;

In this code snippet, we first use the scan method to retrieve a list of keys in the Redis cache. The scan method takes several arguments, such as the cursor position, the MATCH option to filter keys, and the * wildcard to match all keys.

The method returns an array with two elements, where the first element is the next cursor position for subsequent calls, and the second element is an array of keys that match the provided criteria. We then count the number of keys in the array to get the total number of keys in the Redis cache.
