PHP Memcached get() Function Last Updated : 06 Dec, 2021 Summarize Comments Improve Suggest changes Share Like Article Like Report The Memcached::get() function is an inbuilt function of memcached class in PHP which is used to get the value under a given key stored on memcache server. Syntax: public Memcached::get( $key, callable $cache_cb = ?, $$flags = ?): mixed Parameters: This function accepts three parameters that are: key: The key of the item to retrieve.cache_cb: Read-through caching callback or null.flags: Flags to control the returned result. When Memcached::GET_EXTENDED is given, the function will also return the CAS token. Return Values: Returns the value stored in the cache or false otherwise. If the flags is set to Memcached::GET_EXTENDED, an array containing the value and the CAS token is returned instead of only the value. The Memcached::getResultCode() will return Memcached::RES_NOTFOUND if the key does not exist. Below program illustrate the Memcached::set() function in PHP: Example 1: PHP <?php echo "<pre>"; // Server & port details $server = '127.0.0.1'; $port = 11211; // Initiate a new object of memcache $memcacheD = new Memcached(); // Add server if ($memcacheD->addServer($server, $port)) { echo "** server added ** \n"; } else { echo "** issue while creating a server **\n"; } // Set key & value with TTL $key = "GEEKSFORGEEKS"; $value = "computer science portal"; $ttl = 3600; if ($memcacheD->add($key, $value, $ttl)) echo "** added key-value (" . $key . ":" . $value . ")to cache successfully!! **\n"; else echo "** error while adding value to cache!! **\n"; // Get value of key echo "**** FETCHED VALUE FOR KEY :" . $key . " ****\n"; $valD = $memcacheD->get($key); var_dump($valD); ?> Output: ** server added ** ** added key-value (GEEKSFORGEEKS:computer science portal)to cache successfully!! ** **** FETCHED VALUE FOR KEY :GEEKSFORGEEKS **** string(23) "computer science portal" Example 2 (Key-value already stored): PHP <?php echo "<pre>"; // Server & port details $server = '127.0.0.1'; $port = 11211; // Initiate a new object of memcache $memcacheD = new Memcached(); // Add server if ($memcacheD->addServer($server, $port)) { echo "** server added ** \n"; } else { echo "** issue while creating a server **\n"; } // Set key & value with TTL $key = "GEEKSFORGEEKS"; $value = "computer science portal"; $ttl = 3600; if ($memcacheD->add($key, $value, $ttl)) echo "** added key-value (" . $key . ":" . $value . ")to cache successfully!! **\n"; else echo "** error while adding value to cache!! **\n"; // Get value of key echo "**** FETCHED VALUE FOR KEY :" . $key . " ****\n"; $valD = $memcacheD->get($key); var_dump($valD); ?> Output: ** server added ** ** error while adding value to cache!! :: MSG:: NOT STORED ** **** FETCHED VALUE FOR KEY :geeksforgeeks **** string(23) "computer science portal" Reference: https://www.php.net/manual/en/memcached.get.php Comment More infoAdvertise with us S Shivam.Pradhan Follow Improve Article Tags : Web Technologies PHP PHP-function PHP-Memcached Similar Reads JavaScript Tutorial JavaScript is a programming language used to create dynamic content for websites.
