Example
The Alternative PHP Cache (APC) is a free and open opcode cache for PHP. Its goal is to provide a free, open, and robust framework for caching and optimizing PHP intermediate code.
sudo apt-get install php-apc
sudo /etc/init.d/apache2 restart
Add Cache:
apc_add ($key, $value , $ttl);
$key = unique cache key
$value = cache value
$ttl = Time To Live;
Delete Cache:
apc_delete($key);
Set Cache Example:
if (apc_exists($key)) {
echo "Key exists: ";
echo apc_fetch($key);
} else {
echo "Key does not exist";
apc_add ($key, $value , $ttl);
}
APC is nearly 5 times faster than Memcached.
