Laravel Cache Syntax And Example-
Let us go step by step –
Settings –
Databse :
Add a database setup to create table which will store information for database cache-
Laravel Create Database Cache Table –
Schema::create('cache', function($table) {
$table->string('key')->unique();
$table->text('value');
$table->integer('expiration');
});
|
Memcached –
Add settings for memcached. Go to config/cache.php and add the memcached settings-
Laravel Memcached –
'memcached' => [
'driver' => 'memcached',
'servers' => [
[
'host' => '127.0.0.1', 'port' => 11211, 'weight' => 100,
],
],
],

You can add your own host name.
Redis
Laravel Cache Redis Settings –
'redis' => [
'cluster' => false,
'default' => [
'host' => '127.0.0.1',
