如何在 xampp ubuntu 中安装 php-memcache？

Question

I have installed xampp for linux from https://www.apachefriends.org/index.html in my Ubuntu 22.04 OS

After successfully installed, my project is running fine but when I install the php-memchached in my system with the below command but it is not showing in my phpinfo() page.

Command:

sudo apt-get install -y php-memcached

Also I tried with the code to check my Memcached Successfully installed or not. But I got the error message that Class 'Memcached' not found

Code:

$memcached = new Memcached();
$memcached->addServer("127.0.0.1", 8080);
$response = $memcached->get("sample_key");

if($response==true) {
    echo $response;
} else {
    echo "Cache is empty";
    $memcached->set("sample_key", "Sample data from cache") ;
}

Error Output in Yii console:

Class 'Memcached' not found

Please let me know how to install the php-memcached in Xappp for my ubuntu system?

Answer 1

php-memcached extension uses the libmemcached library to provide an API for communicating with memcached servers.

So, This extension requires libmemcached client library .

The steps in outline:

sudo apt-get update
sudo apt-get install -y memcached
sudo apt-get install -y php-memcached
sudo systemctl restart memcached
sudo /opt/lampp/lampp restart

Don't forget to check extension=memcached.so in the php.ini, and path to extension dir...as shingo points out in his commentary
