Memcache::increment -- Increment item's value
Description
int
Memcache::increment ( string key [, int value])
Memcache::increment() increments value of the item on
the specified value. If item with key
key was not numeric and cannot be converted to
number, it will change it's value to value.
Parameter value is optional. It's default value is
1.
Nota:
Do not use Memcache::increment() with item, which was
stored compressed, because consequent call to
Memcache::get() will fail.
Also you can use memcache_increment() function.
See example below.
Ejemplo 1. Memcache::increment() example
<?php
/* procedural API */
$memcache_obj = memcache_connect('memcache_host', 11211);
/* increment counter by 2 */
$current_value = memcache_increment($memcache_obj, 'counter', 2);
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
/* increment counter by 3 */
$current_value = $memcache_obj->increment('counter', 3);
?>
