Brief Introduction to using memcache caching technology in PHP

For more information about how to use memcache cache to accelerate PHP response, see.

Connect to database

The Code is as follows:	Copy code
$ Memcache_obj = memcache_connect ("localhost", 11211 ); Memcache_add ($ memcache_obj, 'var _ key', 'test variable', false, 30 ); $ Memcache_obj-> add ('var _ key', 'test variable', false, 30 );

Instance 1

The Code is as follows:

Copy code

<? Php // Connection $ Mem = new Memcache; $ Mem-> connect ("127.0.0.1", 11211) or die ("cocould not connect "); // Display version $ Version = $ mem-> getVersion (); Echo "Memcached Server version:". $ version. "<br> "; // Save data $ Mem-> set ('key1', 'this is first value', 0, 60 ); $ Val = $ mem-> get ('key1 ′); Echo "Get key1 value:". $ val. "<br> "; // Replace Data $ Mem-> replace ('key1', 'this is replace value', 0, 60 ); $ Val = $ mem-> get ('key1 ′); Echo "Get key1 value:". $ val. "<br> "; // 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 "<br> "; // Delete data $ Mem-> delete ('key1 ′); $ Val = $ mem-> get ('key1 ′); Echo "Get key1 value:". $ val. "<br> "; // Clear all data $ Mem-> flush (); $ Val2 = $ mem-> get ('key2 ′); Echo "Get key2 value:"; Print_r ($ val2 ); Echo "<br> "; // Close the connection $ Mem-> close (); ?>

The Memcache function Library is used in the PECL (PHP Extension Community Library) to build a temporary storage area for large memory data volumes.

In distributed mode, network marketing training is not recommended.
