linux Install PHP’s memcached extension

First make sure there is a difference between memcache and memcached.
Telnet successfully proves that memcache is successfully installed.
phpinfo shows memcached, so that’s no problem

But you said
using the official PHP file to test memcached is useless, the page prompts a 500 error
I wonder if you are using something similar to this code.
$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;
?>

Pay attention to the first line. . $mem = new Memcache;

If your server supports memcached, memcached will be displayed in phpinfo
If it is memcache, only memcache will be displayed

memcached is php an extension of.
So if you use new memcache to instance memcached, it is normal that 500 will appear.

The memcached I installed in linux before is easy to use in java programs. Now I installed memcached on windows and the process already has memcached

First use telnet to connect to the open listening port of memcached on the computer where Windows is located to see if the connection can be made
