Linux Install php memcached extension

You first determine whether it is memcache or memcached the difference between the two.
Telnet successfully proves that the Memcache installation was successful.
Phpinfo show memcached that's fine.

But you said
Using the official test memcached PHP file is useless, page 500 error
I wonder if you are using a code like this.
$mem = new Memcache;
$mem->connect ("192.168.x.y", 11211) or Die ("Could not Connect");

$mem->set (' key ', ' This is a test! ', 0, 60);
$val = $mem->get (' key ');
Echo $val;
?>

Take a look at the first line. $mem = new Memcache;

If your server support is memcached, it will be displayed in Phpinfo memcached
If it's memcache, it'll only show memcache.

memcached is an extension of PHP.
So you use new memcache to go to the instance memcached will be 500 also normal.

What is the relationship between Linux memcached and PHP's memcache extension

Linux memcached is the server-side
PHP Memcache is the client
Client Access server side to access data
