How PHP uses memcache caching technology to improve response speed, memcache cache

The example in this article describes how PHP uses memcache caching technology to improve response speed. Share it with everyone for your reference. The specific analysis is as follows:

Although PHP is already very good and fast, it will still get stuck if there is a large amount of data. Here is an introduction to how to use memcache caching technology in PHP to improve response speed. Friends who need to know more can refer to it.

Memcache can be used under both Linux and Windows systems. Of course, the Linux system is preferred. As for how to install memcache, just google and everything will come out.

Post an example of using memcache below, the code is as follows:

Copy code The code is as follows:

//Connect
$mem = new Memcache;
$mem->connect("127.0.0.1", 11211) or die ("Could not connect");
//Display version
$version = $mem->getVersion();
echo "Memcached Server version: ".$version."
";
//Save data
$mem->set('key1', 'This is first value', 0, 60);
$val = $mem->get('key1');
echo "Get key1 value: " . $val ."
";
//Replace data
$mem->replace('key1', 'This is replace value', 0, 60);
$val = $mem->get('key1');
echo "Get key1 value: " . $val . "
";
//Save the array
$arr = array('aaa', 'bbb', 'ccc', 'ddd');
$mem->set('key2', $arr, 0, 60);
$val2 = $mem->get('key2');
echo "Get key2 value: ";
print_r($val2);
echo "
";
//Delete data
$mem->delete('key1');
$val = $mem->get('key1');
echo "Get key1 value: " . $val . "
";
//Clear all data
$mem->flush();
$val2 = $mem->get('key2');
echo "Get key2 value: ";
print_r($val2);
echo "
";
//Close the connection
$mem->close();
?>

Example 2, the code is as follows:

Copy code The code is as follows:

//Use memcache cache
$mc = memcache_connect('localhost', 11211);
$pn = $mc->get('pid');
echo $pn;
if($pn<1) $pn = 1;
else $pn++;
$mc->set('pid',$pn,0,0); //Set never expires
memcache_close($mc);
?>

I hope this article will be helpful to everyone’s PHP programming design.
